+# معالجة PDF في Java: البحث والتظليل باستخدام GroupDocs
+
+هل وجدت نفسك غارقًا في بحر من المستندات—PDFs، ملفات Word، أو صيغ أخرى وتتمنى أن تتمكن من العثور بسهولة على كلمات أو عبارات محددة؟ **معالجة PDF في Java** تجعل ذلك ممكنًا. في هذا الدليل ستتعلم كيفية البحث عن النص داخل ملفات PDF وإنشاء مقاطع مُظللة باستخدام **GroupDocs.Parser for Java**. سواءً كنت تبني أداة تحليل مستندات أو تقوم بأتمتة مراجعة المحتوى، فإن الخطوات أدناه توفر لك حلاً واضحًا وجاهزًا للإنتاج.
+
+## إجابات سريعة
+- **أي مكتبة تتعامل مع بحث نص PDF في Java؟** GroupDocs.Parser for Java.
+- **هل أحتاج إلى ترخيص للتطوير؟** ترخيص مؤقت يعمل للاختبار؛ الترخيص الكامل مطلوب للإنتاج.
+- **هل يمكنني تظليل عدة مرات ظهور في آن واحد؟** نعم—حدد نصف قطر التظليل وكرر عبر النتائج.
+- **هل البحث حساس لحالة الأحرف؟** بشكل افتراضي يكون غير حساس لحالة الأحرف؛ يمكنك تبديله عبر `SearchOptions`.
+- **ما الصيغ المدعومة؟** أكثر من 50 صيغة إدخال وإخراج، بما في ذلك PDF، DOCX، XLSX، PPTX، HTML، والصور.
+
+## ما هي معالجة PDF في Java؟
+`معالجة PDF في Java` هي مجموعة من العمليات البرمجية—مثل الاستخراج، البحث، وتظليل النص—التي تُجرى على ملفات PDF باستخدام مكتبات Java. باستخدام GroupDocs.Parser يمكنك البحث في أي مستند مدعوم، استرجاع السياق المحيط، وتطبيق تظليلات بصرية، كل ذلك دون فتح الملف في عارض. تتيح لك هذه القدرة بناء أرشيفات سريعة قابلة للبحث وأنابيب مراجعة آلية تتوسع إلى آلاف الصفحات لكل مستند.
+
+## لماذا تستخدم GroupDocs.Parser لمعالجة PDF في Java؟
+يدعم GroupDocs.Parser **أكثر من 50 صيغة ملف** ويمكنه معالجة **ملفات PDF مئات الصفحات** دون تحميل الملف بالكامل إلى الذاكرة، مما يقلل استهلاك RAM بنسبة تصل إلى **70 %** مقارنةً بالطرق البسيطة. تُعيد محرك البحث الخاص به إزاحات دقيقة، مما يتيح لك بناء تظليلات مخصصة في واجهة المستخدم أو تصدير النتائج إلى أنظمة أخرى. المكتبة مُصانة بنشاط، متوافقة مع Java 8+، وتوفر حزم Maven وGradle لتسهيل التكامل.
+
+## المتطلبات المسبقة
+
+قبل أن نبدأ، تأكد من أن لديك هذه الأساسيات جاهزة:
+
+- **بيئة تطوير Java**: JDK 8+ مثبت.
+- **Maven أو Gradle**: لإدارة الاعتمادات وإعداد المشروع.
+- **مكتبة GroupDocs.Parser for Java**: تحميل أو إضافة عبر الاعتماد.
+- **مستند تجريبي**: ملفات PDF أو نصوص للاختبار والبحث داخلها.
+- **معرفة أساسية بـ Java**: الإلمام بالصفوف، الطرق، ومعالجة الملفات.
+
+إذا لم تكن لديك المكتبة بعد، يمكنك الحصول على أحدث نسخة من [GroupDocs Downloads](https://releases.groupdocs.com/parser/java/) أو إضافتها عبر Maven:
+
+```xml
+
+ com.groupdocs
+ groupdocs-parser
+ 21.12
+
+```
+
+## استيراد الحزم
+
+لبدء العملية، لنستورد الفئات الأساسية من GroupDocs.Parser:
+
+`Parser` هي الفئة الأساسية المستخدمة لتحميل والتفاعل مع المستندات. `HighlightOptions` تُكوّن كيفية تظليل النص المتطابق. `SearchOptions` تُعرّف سلوك البحث مثل حساسية الحالة. `SearchResult` تمثل مطابقة فردية تم العثور عليها في المستند.
+
+```java
+import com.groupdocs.parser.Parser;
+import com.groupdocs.parser.search.HighlightOptions;
+import com.groupdocs.parser.search.SearchOptions;
+import com.groupdocs.parser.search.SearchResult;
+```
+
+هذه الاستيرادات تغطي الوظائف الأساسية لتحليل المستندات، ضبط خيارات التظليل، وإجراء عمليات البحث.
+
+## كيف يعمل سير عمل البحث والتظليل؟
+
+حمّل ملف PDF الخاص بك، اضبط كائن `HighlightOptions`، نفّذ `parser.search`، ثم كرّر عبر مجموعة `SearchResult` لإنشاء مقاطع مُظللة. العملية بأكملها تُنفّذ على خطوتين: أولاً، يقرأ المحلل بنية المستند؛ ثانياً، يقوم محرك البحث بمسح تدفق النص مع تطبيق الخيارات التي حددتها. يضمن هذا النهج أداءً عاليًا حتى مع الملفات الكبيرة.
+
+## دليل خطوة بخطوة للبحث عن النص مع التظليل
+
+دعنا نستعرض العملية مقسمة إلى خطوات واضحة وقابلة للإدارة. كل خطوة لها شرحها الخاص لمساعدتك على فهم السبب والطريقة.
+
+### الخطوة 1: تهيئة Parser مع المستند الخاص بك
+
+**ما الذي يحدث هنا؟**
+إنشاء نسخة من فئة `Parser` المرتبطة بملف المستند الخاص بك يتيح لك الوصول إلى محتواه وتحليله.
+
+`Parser` يحمل المستند ويوفر طرقًا لاستخراج النص والبحث.
+
+```java
+try (Parser parser = new Parser("path/to/your/document.pdf")) {
+ // your code here
+}
+```
+
+**في الواقع:**
+عبارة `try-with-resources` تضمن إغلاق الملف بشكل صحيح بعد المعالجة، مما يمنع تسرب الموارد. استبدل `"path/to/your/document.pdf"` بالمسار الدقيق للملف أو URL الخاص بك.
+
+### الخطوة 2: إعداد خيارات التظليل
+
+**لماذا نحدد خيارات التظليل؟**
+قد ترغب في التحكم في مظهر أو سلوك كيفية تظليل نتائج البحث—مثل عدد الأحرف التي تُظهر حول التطابق أو اللون (إن كان مدعومًا).
+
+في هذا المثال، نحدد نصف قطر تظليل قدره 15 حرفًا:
+
+`HighlightOptions` يحدد نصف قطر السياق والإعدادات البصرية للنتائج المُظللة.
+
+```java
+HighlightOptions highlightOptions = new HighlightOptions(15);
+```
+
+هذا يلف النص الموجود بسياق محيط—مثل عدسة مكبرة حول كلماتك المفتاحية—مما يسهل تحديد مكان حدوث التطابقات.
+
+### الخطوة 3: تنفيذ البحث في المستند
+
+**كيف يعمل البحث؟**
+باستخدام `parser.search`، تحدد الكلمة المفتاحية أو العبارة، خيارات البحث، ثم تحصل على مجموعة قابلة للتكرار من كائنات `SearchResult`.
+
+`SearchOptions` تُكوّن معايير البحث مثل حساسية الحالة. `SearchResult` يحتوي على تفاصيل كل تطابق، بما في ذلك النص المتطابق وموقعه.
+
+```java
+Iterable results = parser.search("lorem", new SearchOptions(true, false, false, highlightOptions));
+```
+
+تفصيل مُنشئ `SearchOptions`:
+
+- `true`: تمكين البحث غير حساس لحالة الأحرف.
+- `false`: عدم مطابقة الكلمات الكاملة فقط.
+- `false`: عدم البحث عن أنماط regex.
+- `highlightOptions`: تمرير إعدادات التظليل الخاصة بنا.
+
+هذا الإعداد يبحث عن جميع حالات `"lorem"`، متجاهلًا حالة الأحرف، مع مقاطع مُظللة.
+
+### الخطوة 4: معالجة دعم البحث والنتائج
+
+**تحقق مما إذا كان البحث مدعومًا**
+بعض الصيغ قد لا تدعم البحث — تأكد دائمًا:
+
+`parser.isSearchSupported()` تُعيد قيمة منطقية تشير إلى ما إذا كان تنسيق المستند المحمَّل يسمح بالبحث النصي.
+
+```java
+if (results == null) {
+ System.out.println("Search isn't supported in this document format.");
+ return;
+}
+```
+
+**معالجة كل نتيجة بحث**
+كرر عبر النتائج لاستخراج وعرض المقاطع المطابقة مع التظليل:
+
+كائنات `SearchResult` تُتيح الوصول إلى العبارة المتطابقة والسياق المحيط بها.
+
+```java
+for (SearchResult result : results) {
+ String snippet = String.format("%s%s%s",
+ result.getLeftHighlightItem().getText(),
+ result.getText(),
+ result.getRightHighlightItem().getText());
+ System.out.println(snippet);
+}
+```
+
+## المشكلات الشائعة والحلول
+
+| المشكلة | السبب | الحل |
+|-------|--------|-----|
+| **لا توجد نتائج** | تنسيق المستند غير قابل للبحث | تحقق من أن `parser.isSearchSupported()` يُعيد `true`. |
+| **نصف قطر التظليل يبدو صغيرًا** | نصف القطر الافتراضي هو 10 أحرف | زيادة نصف القطر في `HighlightOptions` (مثال: `new HighlightOptions(20)`). |
+| **خطأ نفاد الذاكرة في ملفات PDF الكبيرة** | تحميل الملف بالكامل إلى الذاكرة | استخدام `Parser` مع وضع البث أو معالجة الملف على أجزاء؛ GroupDocs.Parser يبث الملفات الكبيرة بكفاءة بالفعل. |
+| **حساسية الحالة لا تعمل كما هو متوقع** | `caseSensitive` تم تعيينه بشكل خاطئ | تأكد من أن `SearchOptions(true, …)` يحدد القيمة المنطقية الصحيحة لحساسية الحالة غير الحساسة. |
+
+## الأسئلة المتكررة
+
+**س: هل يمكنني البحث عن عدة كلمات مفتاحية في آن واحد؟**
+**ج:** ليس مباشرة؛ كرّر على كل كلمة مفتاحية أو أنشئ نمط regex يطابق جميع المصطلحات المطلوبة.
+
+**س: هل يؤثر نصف قطر التظليل على جميع صيغ المستندات؟**
+**ج:** بالنسبة لمعظم الصيغ المدعومة يعمل نصف القطر بشكل موحد؛ بعض الصيغ القائمة على الصور تتجاهله لأنها لا تملك طبقات نصية أصلية.
+
+**س: هل يمكنني تغيير ألوان التظليل؟**
+**ج:** `HighlightOptions` يتحكم في نصف قطر السياق؛ الألوان البصرية تعتمد على العارض الذي تستخدمه لعرض PDF، وليس على المحلل نفسه.
+
+**س: هل البحث حساس لحالة الأحرف افتراضيًا؟**
+**ج:** لا. بتعيين `caseSensitive` إلى `false` في `SearchOptions` يصبح البحث غير حساس لحالة الأحرف.
+
+**س: هل يعمل هذا مع الصور الممسوحة ضوئيًا أم فقط مع الملفات النصية؟**
+**ج:** البحث يعمل على المستندات النصية. بالنسبة للصور الممسوحة ضوئيًا تحتاج إلى قدرات OCR، والتي يوفرها GroupDocs OCR كالوحدة المنفصلة.

+- **هل يمكنني استخدام regex للبحث في EPUB؟** نعم – الـ API تقبل كائنات Java Pattern.
+- **كيف تُجري بحثًا حساسًا لحالة الأحرف؟** اضبط `SearchOptions.setIgnoreCase(false)`.
+- **هل أحتاج إلى ترخيص؟** النسخة التجريبية المجانية تعمل للاختبار؛ الترخيص الكامل يزيل الحدود.
+- **ما نسخة Java المطلوبة؟** JDK 8 أو أعلى.
+
+## ما هو GroupDocs.Parser؟
+GroupDocs.Parser هو مكتبة Java تستخرج النصوص، الصور، والبيانات الوصفية من أكثر من 50 صيغة مستند، بما في ذلك EPUB. توفر فئة `Parser` عالية المستوى التي تُجرد التعامل مع الملفات، مما يتيح لك التركيز على منطق البحث بدلاً من التحليل منخفض المستوى. تقوم المكتبة ببث المحتوى بكفاءة، تدعم البيئات ذات الذاكرة المحدودة، وتقدم قدرات بحث مدمجة تعمل مباشرة على النص المستخرج.
+
+## لماذا نستخدم Regex مع GroupDocs.Parser للـ EPUB؟
+- **دعم واسع للصيغ:** يتعامل مع أكثر من 50 صيغة إدخال، بما فيها EPUB، دون الحاجة إلى محولات خارجية.
+- **معالجة كفء للذاكرة:** يبث المحتوى، مما يسمح بالبحث في EPUBs متعددة المئات من الصفحات دون تحميل الملف بالكامل إلى الذاكرة.
+- **مطابقة نمط دقيقة:** يتيح لك Regex تحديد الكلمات الكاملة، العبارات، أو الأنماط المعقدة (مثل التواريخ، أرقام ISBN) في استدعاء واحد.
+
+## المتطلبات المسبقة
+- **Java Development Kit (JDK) 8+** مثبت ومُعد في بيئة التطوير المتكاملة أو أداة البناء الخاصة بك.
+- **GroupDocs.Parser for Java** المكتبة (متوفرة عبر Maven أو تحميل مباشر).
+- إلمام أساسي بصياغة Java ومفاهيم التعابير النمطية.
+
+## كيفية استخدام Regex للبحث النصي في ملفات EPUB؟
+حمّل ملف EPUB باستخدام `new Parser("book.epub")` واستدعِ `search` باستخدام `Pattern` مُجمّع. يتيح لك هذا النهج ذي الخطوتين عزل تحميل الملف عن تنفيذ النمط، مما يضمن أداءً مثاليًا حتى في المجموعات الكبيرة.
+
+### الخطوة 1: تهيئة الـ Parser
+فئة `Parser` هي نقطة الدخول لتحميل ومعالجة ملف EPUB.
+```java
+// ```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/parser/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5
+
+
+```
+```
+
+### الخطوة 2: بناء نمط Regex
+فئة `Pattern` في Java تُجمّع التعبير النمطي. على سبيل المثال، للعثور على أي كلمة تبدأ بـ “list” بعد حرف مسافة، استخدم `\\slist\\w*`.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+// Initialize Parser object with an EPUB file path
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.epub")) {
+ // Your code here
+}
+```
+```
+
+### الخطوة 3: تكوين خيارات البحث
+`SearchOptions` تُكوّن كيفية عمل البحث، مثل حساسية الحالة والبحث الضبابي.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+String epubFilePath = "YOUR_DOCUMENT_DIRECTORY/sample.epub";
+
+try (Parser parser = new Parser(epubFilePath)) {
+ // Further processing steps go here
+}
+```
+```
+
+### الخطوة 4: تنفيذ البحث
+`SearchResult` تمثّل تطابقًا واحدًا، تشمل النص، رقم الصفحة، وإزاحات الأحرف.
+```java
+// ```java
+String regexPattern = \\slist; // Matches any word preceded by whitespace and 'list'
+```
+```
+
+### الخطوة 5: معالجة النتائج
+تكرّر عبر مجموعة `SearchResult` لتسجيل التطابقات، تخزينها في قاعدة بيانات، أو تشغيل سير عمل لاحق مثل الفهرسة أو التنبيه.
+```java
+// ```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options for search
+SearchOptions options = new SearchOptions(true /* case match */, false /* whole word */, true /* fuzzy */);
+```
+```
+
+## كيف تُجري بحثًا حساسًا لحالة الأحرف في Java؟
+اضبط `SearchOptions.setIgnoreCase(false)` لفرض مطابقة الحالة الدقيقة. هذا ضروري عند البحث عن المعرفات، مقتطفات الشيفرة، أو أسماء العلامات التجارية التي يجب أن تحتفظ بحالتها الأصلية.
+
+## حالات الاستخدام الشائعة
+1. **فهرسة المكتبة الرقمية:** إنشاء فهارس قابلة للبحث تلقائيًا لآلاف عناوين EPUB.
+2. **تنسيق المحتوى:** تحديد الأقسام الموضوعية (مثل “Chapter 5”) عبر عدة كتب لأغراض البحث.
+3. **تنقيب البيانات:** استخراج كيانات منظمة مثل أرقام ISBN، التواريخ، أو أسماء المؤلفين باستخدام أنماط regex مخصصة.
+4. **تكامل التعلم الإلكتروني:** تعزيز منصات الدورات بقدرات بحث نصي فوري للمواد التعليمية بصيغ PDF و EPUB.
+
+## نصائح الأداء
+- **تحسين أنماط regex:** فضل الفئات البسيطة على البنى التي تتسبب في تتبع عكسي كثيف للحفاظ على استهلاك منخفض للمعالج.
+- **تقسيم EPUBs الكبيرة:** عالج الفصول بشكل منفصل إذا تجاوز حجم الملف 200 MB لتجنب ارتفاع الذاكرة.
+- **تخزين الاستعلامات المتكررة مؤقتًا:** احفظ نتائج الأنماط الشائعة (مثل الكلمات المفتاحية المتكررة) في خريطة خفيفة في الذاكرة.
+
+## الأسئلة المتكررة
+
+**س: ما هو الفرق بين `search` و `extractText`؟**
+ج: `search` يطبق نمط regex ويعيد فقط القطع المتطابقة، بينما `extractText` يعيد محتوى المستند بالكامل دون تصفية.
+
+**س: هل يمكنني البحث في ملفات EPUB متعددة في استدعاء واحد؟**
+ج: لا، لا توجد مكالمة API واحدة تعالج دفعة، لكن يمكنك التكرار عبر قائمة ملفات، وإعادة استخدام نفس `Pattern` و `SearchOptions` لكل ملف.
+
+**س: كيف يعمل البحث الضبابي؟**
+ج: قم بتمكين وضع الضبابية في `SearchOptions` للسماح بمسافة Levenshtein تصل إلى تعديلين، مما يلتقط الأخطاء الإملائية والاختلافات الطفيفة.
+
+**س: هل هناك حد لحجم المستند؟**
+ج: يمكن لـ GroupDocs.Parser التعامل مع ملفات EPUB حتى 500 MB؛ يجب تقسيم أو بث الملفات الأكبر يدويًا.
+
+**س: هل أحتاج إلى ترخيص للتطوير؟**
+ج: توفر النسخة التجريبية المجانية وصولًا كاملًا إلى API مع علامة مائية للاستخدام؛ الترخيص الدائم يزيل القيود ويمنح حقوقًا تجارية.

+# كيفية البحث في HTML باستخدام GroupDocs.Parser للـ Java
+
+البحث عبر ملفات HTML الضخمة عن أنماط محددة قد يشعر كالبحث عن إبرة في كومة قش. **How to search html** بفعالية هو سؤال شائع لمطوري Java الذين يحتاجون إلى استخراج البيانات، تصفية المحتوى، أو أتمتة تحليل التقارير. في هذا الدليل ستكتشف نهجًا عمليًا يعتمد على regex مدعومًا بـ **GroupDocs.Parser للـ Java** — من الإعداد إلى حل المشكلات — لتتمكن من تحديد أي نمط نصي داخل مستندات HTML بثقة.
+
+## إجابات سريعة
+- **ما المكتبة التي تتعامل مع بحث regex في HTML باستخدام Java؟** GroupDocs.Parser for Java.
+- **هل أحتاج إلى ترخيص للتطوير؟** الإصدار التجريبي المجاني يعمل للاختبار؛ الترخيص الدائم مطلوب للإنتاج.
+- **ما نسخة Java المطلوبة؟** Java 8 أو أعلى (يوصى بـ JDK 11).
+- **هل يمكنني البحث في ملفات متعددة في آن واحد؟** نعم — غلف استدعاء الـ parser داخل حلقة أو استخدم Java streams.
+- **ما الأداء المتوقع؟** GroupDocs.Parser يعالج ملفات HTML مكوّنة من 500 صفحة في أقل من ثانيتين على خادم عادي.
+
+## ما هو “how to search html” باستخدام regex؟
+**“How to search html”** يشير إلى استخدام التعابير النمطية (regular expressions) لتحديد أنماط النص داخل شيفرة HTML. هذه التقنية تتيح لك تحديد الكلمات، الأرقام، أو العلامات المخصصة دون الحاجة إلى تحليل شجرة DOM بالكامل. من خلال تطبيق regex مباشرة على مصدر HTML الخام، يمكن للمطورين استخراج بيانات محددة بسرعة، التحقق من صحة المحتوى، أو تصفية الأقسام، مما يجعلها بديلًا خفيفًا للمعالجة الكاملة لشجرة DOM.
+
+## لماذا نستخدم GroupDocs.Parser للـ Java في عمليات بحث regex؟
+GroupDocs.Parser يدعم **أكثر من 70** تنسيقًا للإدخال والإخراج — بما في ذلك HTML، DOCX، XLSX، وPDF — مع معالجة مستندات مكوّنة من مئات الصفحات دون تحميل الملف بالكامل في الذاكرة. تسمح لك الفئة الأصلية `SearchOptions` بتمكين التعابير النمطية، التحكم في حساسية الحالة، وتحديد عدد النتائج، مما يوفر عمليات مسح سريعة وفعّالة في استهلاك الذاكرة.
+
+## المتطلبات المسبقة
+1. **GroupDocs.Parser للـ Java** (أحدث نسخة، مثلاً 25.5 أو أحدث).
+2. **Java Development Kit** 8 أو أحدث مثبت ومُعد في بيئة التطوير المتكاملة الخاصة بك.
+3. إلمام أساسي بـ **تركيب regex في Java** (مثلاً `\d+`, `\bSub\w*`).
+
+## إعداد GroupDocs.Parser للـ Java
+لبدء العملية، أضف تبعية Maven إلى ملف `pom.xml` الخاص بك:
+
+```xml
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5
+
+```
+
+للتنزيلات المباشرة، زر [إصدارات GroupDocs.Parser للـ Java](https://releases.groupdocs.com/parser/java/) للحصول على أحدث نسخة.
+
+**اكتساب الترخيص**
+- **الإصدار التجريبي المجاني** – استكشف الميزات الأساسية دون تكلفة.
+- **ترخيص مؤقت** – اطلب مفتاح اختبار ممتد من [موقع GroupDocs](https://purchase.groupdocs.com/temporary-license/).
+- **شراء** – احصل على ترخيص كامل للاستخدام الإنتاجي غير المحدود.
+
+**التهيئة**
+بعد إضافة المكتبة، قم بتهيئة تطبيق Java الخاص بك لاستخدام GroupDocs.Parser:
+
+```java
+import com.groupdocs.parser.Parser;
+
+public class SetupExample {
+ public static void main(String[] args) {
+ String filePath = "path/to/your/document.html";
+ try (Parser parser = new Parser(filePath)) {
+ // Initialization complete, ready to parse and search!
+ } catch (Exception e) {
+ e.printStackTrace();
+ }
+ }
+}
+```
+
+## كيفية البحث في HTML باستخدام GroupDocs.Parser للـ Java؟
+حمّل ملف HTML الخاص بك باستخدام الفئة `Parser` ونفّذ بحثًا regex في سطرين فقط من الشيفرة. الفئة `Parser` هي نقطة الدخول التي تقرأ وتُحلل أنواع المستندات المدعومة، وتُظهر طرقًا لاستخراج النص والبحث. من خلال تكوين `SearchOptions`, تُخبر الـ parser بأن يتعامل مع النمط الخاص بك كتعابير نمطية، مع إمكانية تمكين المطابقة حساسة لحالة الأحرف أو مطابقة الكلمة الكاملة.
+
+### تنفيذ خطوة بخطوة
+
+### الخطوة 1: تعريف نمط التعابير النمطية الخاص بك
+أولاً، صغ نمط الـ regex الذي يطابق النص الذي تحتاجه. في هذا المثال نبحث عن كلمات تبدأ بـ **“Sub”** متبوعة برقم (مثلاً `Sub1`, `Sub9`).
+
+```java
+String regexPattern = "Sub[0-9]";
+```
+
+### الخطوة 2: إعداد خيارات البحث
+`SearchOptions` هو كائن تكوين يحدد سلوك البحث مثل وضع regex وحساسية الحالة.
+قم بتكوين كائن `SearchOptions` لتفعيل وضع regex، ضبط حساسية الحالة، وتحديد ما إذا كان يجب مطابقة الكلمات الكاملة فقط. `SearchOptions` هو حاوية إعدادات تخبر الـ parser كيفية تنفيذ البحث.
+
+```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options: case-sensitive, whole word, use regex
+SearchOptions options = new SearchOptions(true, false, true);
+```
+
+### الخطوة 3: تنفيذ البحث
+استدعِ طريقة `search` على كائن `Parser`، مع تمرير مسار ملف HTML، النمط، والخيارات. تُعيد الطريقة مجموعة من كائنات `SearchResult`، كل منها يحتوي على النص المطابق وموقعه في المستند.
+
+```java
+import com.groupdocs.parser.data.SearchResult;
+
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.html")) {
+ Iterable results = parser.search(regexPattern, options);
+
+ for (SearchResult result : results) {
+ System.out.println(String.format("At %d: %s", result.getPosition(), result.getText()));
+ }
+} catch (Exception e) {
+ e.printStackTrace();
+}
+```
+
+**خيارات التكوين الرئيسية**
+- **حساسية الحالة** – اضبط `true` للمطابقات الدقيقة لحالة الأحرف.
+- **بحث كلمة كاملة** – `false` يشمل المطابقات الجزئية.
+- **استخدام التعابير النمطية** – يجب أن يكون `true` لتمكين معالجة regex.
+
+## المشكلات الشائعة والحلول
+- **مسار الملف غير صحيح** – تحقق من أن ملف HTML يمكن الوصول إليه من دليل عمل تطبيقك.
+- **صياغة regex غير صالحة** – اختبر نمطك باستخدام أداة اختبار regex على الإنترنت قبل دمجه في الشيفرة.
+- **تسريبات الذاكرة** – احرص دائمًا على إغلاق كائن `Parser` أو استخدم try‑with‑resources لضمان تحرير التدفقات.
+
+## التطبيقات العملية
+1. **استخراج البيانات** – استخراج أرقام الفواتير، المعرفات، أو الطوابع الزمنية من تقارير HTML الضخمة.
+2. **تصفية المحتوى** – إزالة أو وضع علامة على الأقسام التي تحتوي على كلمات محظورة تلقائيًا.
+3. **تحليل السجلات** – فحص سجلات HTML المهيأة للبحث عن أنماط الأخطاء أو مؤشرات الأداء.
+4. **خطوط ETL** – دمج الـ parser في سير عمل إدخال البيانات الذي يُطبع محتوى الويب المستخرج.
+
+## اعتبارات الأداء
+عند التعامل مع مجموعات HTML الكبيرة، احرص على مراعاة النصائح التالية:
+- **تحسين أنماط regex** – تجنّب التراجع الزائد؛ استخدم المجموعات الذرية أو الكميات المتملّكة عندما يكون ذلك ممكنًا.
+- **تبسيط استهلاك الذاكرة** – غلف عملية التحليل داخل كتلة try‑with‑resources للسماح للـ JVM باستعادة الذاكرة بسرعة.
+- **المعالجة المتوازية** – استفد من `ForkJoinPool` في Java للبحث في مستندات متعددة بشكل متزامن، مع توسع خطي على الخوادم متعددة الأنوية.
+
+## الأسئلة المتكررة
+
+**س: ما هو التعبير النمطي؟**
+ج: التعبير النمطي (regex) هو لغة مختصرة قائمة على الأنماط لمطابقة تسلسلات الأحرف داخل السلاسل، تُستخدم على نطاق واسع للتحقق، البحث، وتعديل النص.
+
+**س: هل يمكن لـ GroupDocs.Parser معالجة ملفات غير HTML؟**
+ج: نعم، يدعم أكثر من 70 تنسيقًا — بما في ذلك PDF، DOCX، XLSX، وPPTX — لذا يعمل منطق البحث نفسه عبر أنواع المستندات المتنوعة.
+
+**س: كيف يجب أن أتعامل مع أخطاء التحليل؟**
+ج: احط الشيفرة الخاصة بالتحليل بكتلة try‑catch، والتقط `ParserException` لتسجيل المشكلة وضمان إغلاق الموارد.
+
+**س: الـ regex الخاص بي لا يُعيد أي نتائج — ما الخطأ؟**
+ج: تحقق مرة أخرى من النمط للتأكد من صحة الأحرف المُهربة، راجع إعدادات حساسية الحالة، وتأكد من وجود النص المستهدف فعليًا في مصدر HTML.
+
+**س: هل هناك حد لحجم ملفات HTML؟**
+ج: يمكن لـ GroupDocs.Parser معالجة ملفات تصل إلى 2 GB؛ بالنسبة لملفات HTML الضخمة جدًا، يُنصح بتقسيمها أو بث أقسام منها للبقاء ضمن حدود الذاكرة.
+
+## الخلاصة
+باتباع هذا الدليل، أصبحت الآن تعرف **how to search html** المستندات باستخدام محرك regex قوي مدمج في GroupDocs.Parser للـ Java. يمكنك بسرعة تحديد الأنماط، استخراج البيانات ذات المعنى، ودمج الحل في تطبيقات Java الأكبر أو خطوط البيانات.

+# Java PDF 处理：搜索与高亮（使用 GroupDocs）
+
+是否曾经在大量文档——PDF、Word 文件或其他格式的海洋中感到无从下手，并希望能够轻松找到特定的单词或短语？**Java PDF 处理**可以实现这一点。在本指南中，您将学习如何在 PDF 中搜索文本并使用 **GroupDocs.Parser for Java** 生成高亮片段。无论您是在构建文档分析工具还是自动化内容审查，以下步骤都为您提供了清晰、可用于生产的解决方案。
+
+## 快速答案
+- **哪个库在 Java 中处理 PDF 文本搜索？** GroupDocs.Parser for Java.
+- **开发是否需要许可证？** 临时许可证可用于测试；生产环境需要正式许可证。
+- **我可以一次高亮多个出现吗？** 可以——设置高亮半径并遍历结果。
+- **搜索是否区分大小写？** 默认情况下不区分大小写；您可以通过 `SearchOptions` 切换。
+- **支持哪些格式？** 超过 50 种输入和输出格式，包括 PDF、DOCX、XLSX、PPTX、HTML 和图像。
+
+## 什么是 Java PDF 处理？
+`Java PDF processing` 是使用 Java 库对 PDF 文件执行的一系列编程操作——如提取、搜索和高亮文本。使用 GroupDocs.Parser，您可以搜索任何受支持的文档，获取周围上下文，并应用可视化高亮，而无需在查看器中打开文件。此功能使您能够构建快速、可搜索的档案以及可扩展至每个文档数千页的自动化审查流水线。
+
+## 为什么在 Java PDF 处理中使用 GroupDocs.Parser？
+GroupDocs.Parser 支持 **50+ 种文件格式**，并且能够在不将整个文件加载到内存中的情况下处理 **数百页的 PDF**，相比于朴素方法可将内存使用降低至 **70 %**。其搜索引擎返回精确的偏移量，使您能够构建自定义 UI 高亮或将结果导出到其他系统。该库持续维护，兼容 Java 8+，并提供 Maven 和 Gradle 的构件，便于集成。
+
+## 先决条件
+
+在动手之前，请确保您已准备好以下必备条件：
+
+- **Java 开发环境**：已安装 JDK 8+。
+- **Maven 或 Gradle**：用于依赖管理和项目设置。
+- **GroupDocs.Parser for Java 库**：下载或通过依赖添加。
+- **示例文档**：用于搜索的测试 PDF 或文本。
+- **基本的 Java 知识**：熟悉类、方法和文件处理。
+
+如果您尚未拥有该库，可以从 [GroupDocs Downloads](https://releases.groupdocs.com/parser/java/) 获取最新版本，或通过 Maven 添加：
+
+```xml
+
+ com.groupdocs
+ groupdocs-parser
+ 21.12
+
+```
+
+## 导入包
+
+首先，让我们导入 GroupDocs.Parser 中的必要类：
+
+`Parser` 是用于加载和交互文档的主要类。`HighlightOptions` 配置匹配文本的高亮方式。`SearchOptions` 定义搜索行为，例如是否区分大小写。`SearchResult` 表示文档中找到的单个匹配项。
+
+```java
+import com.groupdocs.parser.Parser;
+import com.groupdocs.parser.search.HighlightOptions;
+import com.groupdocs.parser.search.SearchOptions;
+import com.groupdocs.parser.search.SearchResult;
+```
+
+这些导入涵盖了解析文档、设置高亮选项以及执行搜索操作的核心功能。
+
+## 搜索与高亮工作流是如何运作的？
+
+加载 PDF，配置 `HighlightOptions` 对象，执行 `parser.search`，然后遍历 `SearchResult` 集合以构建高亮片段。整个过程分为两步：第一步，解析器读取文档结构；第二步，搜索引擎扫描文本流并应用您定义的选项。此方法即使在大文件上也能确保高性能。
+
+## 逐步指南：搜索文本并高亮
+
+让我们逐步浏览该过程，分解为易于管理的清晰步骤。每一步都有相应的解释，帮助您了解原因和做法。
+
+### 步骤 1：使用文档初始化 Parser
+
+**这里发生了什么？**
+创建与文档文件关联的 `Parser` 类实例，使您能够访问并分析其内容。
+
+`Parser` 加载文档并提供文本提取和搜索的方法。
+
+```java
+try (Parser parser = new Parser("path/to/your/document.pdf")) {
+ // your code here
+}
+```
+
+**实际情况：**
+`try-with-resources` 语句确保在处理后正确关闭文件，防止资源泄漏。将 `"path/to/your/document.pdf"` 替换为您的实际文件路径或 URL。
+
+### 步骤 2：设置高亮选项
+
+**为什么要定义高亮选项？**
+您可能希望控制搜索命中高亮的外观或行为——例如在匹配周围显示的字符数或颜色（如果支持）。
+
+在本例中，我们将高亮半径设置为 15 个字符：
+
+`HighlightOptions` 指定高亮搜索命中的上下文半径和可视设置。
+
+```java
+HighlightOptions highlightOptions = new HighlightOptions(15);
+```
+
+这会将找到的文本与周围上下文一起包装——就像放大镜围绕关键字——使您更容易发现匹配位置。
+
+### 步骤 3：在文档中执行搜索
+
+**搜索是如何工作的？**
+使用 `parser.search`，您指定关键字或短语、搜索选项，然后获得一个可迭代的 `SearchResult` 对象集合。
+
+`SearchOptions` 配置搜索参数，如是否区分大小写。`SearchResult` 包含每个匹配的详细信息，包括匹配的文本及其位置。
+
+```java
+Iterable results = parser.search("lorem", new SearchOptions(true, false, false, highlightOptions));
+```
+
+拆解 `SearchOptions` 构造函数：
+
+- `true`：启用不区分大小写的搜索。
+- `false`：不只匹配完整单词。
+- `false`：不搜索正则表达式模式。
+- `highlightOptions`：传入我们的高亮配置。
+
+此设置搜索所有 `"lorem"` 出现，忽略大小写，并生成高亮片段。
+
+### 步骤 4：处理搜索支持和结果
+
+**检查是否支持搜索**
+某些格式可能不支持搜索——请始终确认：
+
+`parser.isSearchSupported()` 返回一个布尔值，指示加载的文档格式是否允许文本搜索。
+
+```java
+if (results == null) {
+ System.out.println("Search isn't supported in this document format.");
+ return;
+}
+```
+
+**处理每个搜索命中**
+遍历结果以提取并显示带高亮的匹配片段：
+
+`SearchResult` 对象提供对匹配短语及其周围上下文的访问。
+
+```java
+for (SearchResult result : results) {
+ String snippet = String.format("%s%s%s",
+ result.getLeftHighlightItem().getText(),
+ result.getText(),
+ result.getRightHighlightItem().getText());
+ System.out.println(snippet);
+}
+```
+
+## 常见问题及解决方案
+
+| 问题 | 原因 | 解决方案 |
+|-------|--------|-----|
+| **未返回结果** | 文档格式不支持搜索 | 验证 `parser.isSearchSupported()` 返回 `true`。 |
+| **高亮半径似乎太小** | 默认半径为 10 个字符 | 在 `HighlightOptions` 中增加半径（例如 `new HighlightOptions(20)`）。 |
+| **大 PDF 导致内存不足错误** | 整个文件被加载到内存中 | 使用带流模式的 `Parser` 或分块处理文件；GroupDocs.Parser 已高效地对大文件进行流式处理。 |
+| **大小写敏感性未按预期工作** | `caseSensitive` 标志设置错误 | 确保 `SearchOptions(true, …)` 正确设置了大小写不敏感的布尔值。 |
+
+## 常见问题
+
+**Q: 我可以一次搜索多个关键字吗？**
+A: 不能直接实现；需要遍历每个关键字或构建匹配所有所需词的正则表达式模式。
+
+**Q: 高亮半径会影响所有文档格式吗？**
+A: 对大多数受支持的格式，半径表现一致；某些基于图像的格式会忽略它，因为它们缺乏原生文本层。
+
+**Q: 我可以更改高亮颜色吗？**
+A: `HighlightOptions` 控制上下文半径；可视颜色取决于您用于渲染 PDF 的查看器，而非解析器本身。
+
+**Q: 搜索默认区分大小写吗？**
+A: 不区分。通过在 `SearchOptions` 中将 `caseSensitive` 设置为 `false`，搜索将变为不区分大小写。
+
+**Q: 这仅适用于文本文件还是也适用于扫描图像？**
+A: 搜索适用于基于文本的文档。对于扫描图像，您需要 OCR 能力，GroupDocs OCR 作为单独模块提供。

+# 如何使用正则表达式在 EPUB 文本搜索中使用 GroupDocs.Parser
+
+在本实战指南中，您将了解 **如何使用正则表达式** 在 EPUB 文件中使用 GroupDocs.Parser for Java 进行文本搜索。无论您是构建数字图书馆索引器，还是需要在成千上万的电子书中定位特定短语，掌握正则表达式搜索都能为您节省时间并提高准确性。我们将逐步演示设置、关键类和实用模式，同时涵盖 **如何高效搜索 epub** 文件。
+
+## 快速答案
+- **什么库在 Java 中解析 EPUB？** GroupDocs.Parser for Java.
+- **我可以使用正则表达式进行 EPUB 搜索吗？** 是的 – API 接受 Java Pattern 对象。
+- **如何执行区分大小写的搜索？** 设置 `SearchOptions.setIgnoreCase(false)`。
+- **我需要许可证吗？** 免费试用可用于测试；完整许可证可移除限制。
+- **需要哪个 Java 版本？** JDK 8 或更高。
+
+## 什么是 GroupDocs.Parser？
+GroupDocs.Parser 是一个 Java 库，可从超过 50 种文档格式（包括 EPUB）中提取文本、图像和元数据。它提供了高级的 `Parser` 类，抽象文件处理，让您专注于搜索逻辑而不是底层解析。该库高效地流式传输内容，支持内存受限的环境，并提供内置的搜索功能，可直接在解析后的文本上工作。
+
+## 为什么在 EPUB 中使用 GroupDocs.Parser 与正则表达式？
+- **广泛的格式支持：** 处理 50 多种输入格式，包含 EPUB，无需外部转换器。
+- **内存高效处理：** 流式传输内容，允许在不将整个文件加载到 RAM 的情况下搜索数百页的 EPUB。
+- **精确的模式匹配：** 正则表达式让您能够在一次调用中定位完整单词、短语或复杂模式（例如日期、ISBN）。
+
+## 前置条件
+- **Java Development Kit (JDK) 8+** 已安装并在您的 IDE 或构建工具中配置。
+- **GroupDocs.Parser for Java** 库（可通过 Maven 或直接下载获取）。
+- 对 Java 语法和正则表达式概念有基本了解。
+
+## 如何使用正则表达式在 EPUB 文件中搜索文本？
+
+使用 `new Parser("book.epub")` 加载您的 EPUB，并使用已编译的 `Pattern` 调用 `search`。这种两步方法将文件加载与模式执行分离，即使在大型集合上也能确保最佳性能。
+
+### 步骤 1：初始化 Parser
+`Parser` 类是加载和处理 EPUB 文件的入口点。
+```java
+// ```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/parser/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5
+
+
+```
+```
+
+### 步骤 2：构建正则表达式模式
+Java 的 `Pattern` 类编译正则表达式。例如，要查找在空白字符后以 “list” 开头的任意单词，可使用 `\\slist\\w*`。
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+// Initialize Parser object with an EPUB file path
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.epub")) {
+ // Your code here
+}
+```
+```
+
+### 步骤 3：配置搜索选项
+`SearchOptions` 配置搜索的运行方式，例如大小写敏感性和模糊匹配。
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+String epubFilePath = "YOUR_DOCUMENT_DIRECTORY/sample.epub";
+
+try (Parser parser = new Parser(epubFilePath)) {
+ // Further processing steps go here
+}
+```
+```
+
+### 步骤 4：执行搜索
+`SearchResult` 表示单个匹配项，包括文本、页码和字符偏移量。
+```java
+// ```java
+String regexPattern = \\slist; // Matches any word preceded by whitespace and 'list'
+```
+```
+
+### 步骤 5：处理结果
+遍历 `SearchResult` 集合以记录匹配项、将其存入数据库，或触发下游工作流，如索引或警报。
+```java
+// ```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options for search
+SearchOptions options = new SearchOptions(true /* case match */, false /* whole word */, true /* fuzzy */);
+```
+```
+
+## 如何在 Java 中执行区分大小写的搜索？
+设置 `SearchOptions.setIgnoreCase(false)` 以强制精确的大小写匹配。这在搜索标识符、代码片段或必须保留原始大小写的品牌名称时尤为重要。
+
+## 常见使用场景
+- **数字图书馆索引：** 自动为数千个 EPUB 标题生成可搜索的索引。
+- **内容策展：** 在多本书中定位主题章节（例如 “Chapter 5”）以供研究。
+- **数据挖掘：** 使用定制的正则表达式模式提取结构化实体，如 ISBN、日期或作者姓名。
+- **电子学习集成：** 为课程平台增强即时全文搜索功能，支持课程材料的 PDF 和 EPUB。
+
+## 性能提示
+- **优化正则表达式模式：** 优先使用简单的字符类而非回溯开销大的构造，以降低 CPU 使用率。
+- **分块处理大型 EPUB：** 如果文件超过 200 MB，建议逐章节处理，以避免内存峰值。
+- **缓存频繁查询：** 将常用模式的结果（例如常见关键字）存储在轻量级的内存映射中。
+
+## 常见问题解答
+
+**Q: `search` 与 `extractText` 有何区别？**
+A: `search` 应用正则表达式模式，仅返回匹配的片段，而 `extractText` 返回整个文档内容，不进行过滤。
+
+**Q: 我可以一次调用搜索多个 EPUB 文件吗？**
+A: 单个 API 调用无法批量处理，但您可以遍历文件列表，对每个文件复用相同的 `Pattern` 和 `SearchOptions`。
+
+**Q: 模糊搜索是如何工作的？**
+A: 在 `SearchOptions` 中启用模糊模式，可允许最多两次编辑的 Levenshtein 距离，从而捕获拼写错误和细微变体。
+
+**Q: 文档大小是否有限制？**
+A: GroupDocs.Parser 可处理最高 500 MB 的 EPUB；更大的文件应手动拆分或流式处理。
+
+**Q: 开发是否需要许可证？**
+A: 免费试用提供完整的 API 访问并带有使用水印；永久许可证可移除限制并授予商业使用权。

+import com.groupdocs.parser.Parser;
+
+public class SetupExample {
+ public static void main(String[] args) {
+ String filePath = "path/to/your/document.html";
+ try (Parser parser = new Parser(filePath)) {
+ // Initialization complete, ready to parse and search!
+ } catch (Exception e) {
+ e.printStackTrace();
+ }
+ }
+}
+```
+
+## 如何使用 GroupDocs.Parser for Java 搜索 HTML？
+使用 `Parser` 类加载您的 HTML 文件，并仅用两行代码执行正则搜索。`Parser` 类是读取和解析受支持文档类型的入口点，提供文本提取和搜索的方法。通过配置 `SearchOptions`，您可以让解析器将模式视为正则表达式，可选地启用大小写敏感或全词匹配。
+
+### 步骤实现
+
+### 步骤 1：定义正则表达式模式
+首先，编写匹配所需文本的正则模式。在本例中，我们查找以 **“Sub”** 开头并跟随数字的单词（例如 `Sub1`、`Sub9`）。
+
+```java
+String regexPattern = "Sub[0-9]";
+```
+
+### 步骤 2：设置搜索选项
+`SearchOptions` 是一个配置对象，用于指定搜索行为，如正则模式和大小写敏感性。
+配置 `SearchOptions` 对象以激活正则模式、设置大小写敏感性，并决定是否仅匹配完整单词。`SearchOptions` 是一个配置持有者，指示解析器如何执行搜索。
+
+```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options: case-sensitive, whole word, use regex
+SearchOptions options = new SearchOptions(true, false, true);
+```
+
+### 步骤 3：执行搜索
+在 `Parser` 实例上调用 `search` 方法，传入 HTML 文件路径、模式和选项。该方法返回 `SearchResult` 对象的集合，每个对象包含匹配的文本及其在文档中的位置。
+
+```java
+import com.groupdocs.parser.data.SearchResult;
+
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.html")) {
+ Iterable results = parser.search(regexPattern, options);
+
+ for (SearchResult result : results) {
+ System.out.println(String.format("At %d: %s", result.getPosition(), result.getText()));
+ }
+} catch (Exception e) {
+ e.printStackTrace();
+}
+```
+
+**关键配置选项**
+- **Case Sensitivity** – 设置 `true` 以进行精确大小写匹配。
+- **Whole Word Search** – `false` 包含部分匹配。
+- **Use Regular Expressions** – 必须为 `true` 才能启用正则处理。
+
+## 常见问题及解决方案
+- **Incorrect file path** – 验证 HTML 文件是否可从应用程序的工作目录访问。
+- **Invalid regex syntax** – 在将模式嵌入代码前，使用在线正则测试工具进行测试。
+- **Memory leaks** – 始终关闭 `Parser` 实例或使用 try‑with‑resources 确保流被释放。
+
+## 实际应用
+在 HTML 中使用正则驱动的搜索可打开许多实际场景的大门：
+
+1. **Data Extraction** – 从批量 HTML 报告中提取发票号码、ID 或时间戳。
+2. **Content Filtering** – 自动删除或标记包含禁止关键字的章节。
+3. **Log Analysis** – 扫描 HTML 格式的日志以查找错误模式或性能指标。
+4. **ETL Pipelines** – 将解析器集成到数据摄取工作流中，以规范化网络抓取的内容。
+
+## 性能考虑因素
+处理大型 HTML 语料库时，请牢记以下提示：
+
+- **Optimize regex patterns** – 避免过度回溯；在可能的情况下使用原子组或占有量词。
+- **Streamline memory usage** – 将解析包装在 try‑with‑resources 块中，以便 JVM 及时回收缓冲区。
+- **Parallel processing** – 利用 Java 的 `ForkJoinPool` 并发搜索多个文档，在多核服务器上实现线性扩展。
+
+## 常见问答
+
+**Q: 什么是正则表达式？**
+A: 正则表达式（regex）是一种简洁的基于模式的语言，用于匹配字符串中的字符序列，广泛用于验证、搜索和文本操作。
+
+**Q: GroupDocs.Parser 能处理非 HTML 文件吗？**
+A: 可以，它支持超过 70 种格式——包括 PDF、DOCX、XLSX 和 PPTX——因此相同的搜索逻辑适用于各种文档类型。
+
+**Q: 我该如何处理解析错误？**
+A: 将解析代码放在 try‑catch 块中，捕获 `ParserException` 以记录问题并确保资源关闭。
+
+**Q: 我的正则没有返回结果——哪里出错了？**
+A: 仔细检查模式中的转义字符，确认大小写敏感设置，并确保目标文本确实存在于 HTML 源码中。
+
+**Q: HTML 文件有大小限制吗？**
+A: GroupDocs.Parser 可以处理高达 2 GB 的文件；对于极大的 HTML 文件，考虑将其拆分或分段流式处理，以保持在内存限制内。
+

+ - answer: '`HighlightOptions` controls context radius; visual colors depend on the
+ viewer you use to render the PDF, not the parser itself.'
+ question: Can I change highlight colors?
+ - answer: No. By setting `caseSensitive` to `false` in `SearchOptions`, the search
+ becomes case‑insensitive.
+ question: Is search case‑sensitive by default?
+ - answer: Search works on text‑based documents. For scanned images you need OCR
+ capabilities, which GroupDocs OCR provides as a separate module.

+# Java PDF zpracování: Vyhledávání a zvýrazňování pomocí GroupDocs
+
+Už jste se někdy topili v moři dokumentů—PDF, Word souborech nebo jiných formátech—a přáli si snadno najít konkrétní slova nebo fráze? **Java PDF processing** makes that possible. V tomto průvodci se naučíte, jak vyhledávat text v PDF a generovat zvýrazněné úryvky pomocí **GroupDocs.Parser for Java**. Ať už vytváříte nástroj pro analýzu dokumentů nebo automatizujete kontrolu obsahu, níže uvedené kroky vám poskytnou jasné, připravené řešení pro produkci.
+
+## Rychlé odpovědi
+- **Která knihovna provádí vyhledávání textu v PDF v Javě?** GroupDocs.Parser for Java.
+- **Potřebuji licenci pro vývoj?** Dočasná licence funguje pro testování; plná licence je vyžadována pro produkci.
+- **Mohu zvýraznit více výskytů najednou?** Ano—nastavte rádius zvýraznění a iterujte přes výsledky.
+- **Je vyhledávání citlivé na velikost písmen?** Ve výchozím nastavení není citlivé na velikost písmen; můžete to přepnout pomocí `SearchOptions`.
+- **Jaké formáty jsou podporovány?** Více než 50 vstupních a výstupních formátů, včetně PDF, DOCX, XLSX, PPTX, HTML a obrázků.
+
+## Co je java pdf processing?
+`Java PDF processing` je sada programových operací—jako je extrakce, vyhledávání a zvýrazňování textu—prováděných na PDF souborech pomocí Java knihoven. S GroupDocs.Parser můžete vyhledávat v jakémkoli podporovaném dokumentu, získat okolní kontext a aplikovat vizuální zvýraznění, a to vše bez otevření souboru ve vieweru. Tato schopnost vám umožní vytvořit rychlé, prohledávatelné archivy a automatizované revizní pipeline, které škálují na tisíce stránek v jednom dokumentu.
+
+## Proč použít GroupDocs.Parser pro java pdf processing?
+GroupDocs.Parser podporuje **více než 50 formátů souborů** a může zpracovávat **PDF s několika stovkami stránek** bez načítání celého souboru do paměti, čímž snižuje využití RAM až o **70 %** ve srovnání s naivními přístupy. Jeho vyhledávací engine vrací přesné offsety, což vám umožní vytvářet vlastní UI zvýraznění nebo exportovat výsledky do jiných systémů. Knihovna je aktivně udržována, kompatibilní s Java 8+ a nabízí artefakty pro Maven i Gradle pro snadnou integraci.
+
+## Předpoklady
+
+Než si zapřáhneme rukávy, ujistěte se, že máte připravené tyto nezbytnosti:
+
+- **Java Development Environment**: Nainstalovaný JDK 8+.
+- **Maven nebo Gradle**: Pro správu závislostí a nastavení projektu.
+- **GroupDocs.Parser for Java library**: Stáhněte nebo přidejte jako závislost.
+- **Ukázkový dokument**: Testovací PDF nebo texty, ve kterých budete vyhledávat.
+- **Základní znalost Javy**: Znalost tříd, metod a práce se soubory.
+
+Pokud ještě knihovnu nemáte, můžete si stáhnout nejnovější verzi z [GroupDocs Downloads](https://releases.groupdocs.com/parser/java/) nebo ji přidat přes Maven:
+
+```xml
+
+ com.groupdocs
+ groupdocs-parser
+ 21.12
+
+```
+
+## Import balíčků
+
+Na úvod importujme nezbytné třídy z GroupDocs.Parser:
+
+`Parser` je hlavní třída používaná k načtení a interakci s dokumenty. `HighlightOptions` konfiguruje, jak je nalezený text zvýrazněn. `SearchOptions` definuje chování vyhledávání, jako je citlivost na velikost písmen. `SearchResult` představuje jednotlivý výskyt nalezený v dokumentu.
+
+```java
+import com.groupdocs.parser.Parser;
+import com.groupdocs.parser.search.HighlightOptions;
+import com.groupdocs.parser.search.SearchOptions;
+import com.groupdocs.parser.search.SearchResult;
+```
+
+Tyto importy pokrývají základní funkce pro parsování dokumentů, nastavení možností zvýraznění a provádění vyhledávacích operací.
+
+## Jak funguje pracovní postup vyhledávání a zvýrazňování?
+
+Nahrajte své PDF, nakonfigurujte objekt `HighlightOptions`, spusťte `parser.search` a poté iterujte přes kolekci `SearchResult`, abyste vytvořili zvýrazněné úryvky. Celý proces probíhá ve dvoukrokovém režimu: nejprve parser načte strukturu dokumentu; druhý krok vyhledávací engine prohledá textový tok s aplikovanými možnostmi, které jste definovali. Tento přístup zajišťuje vysoký výkon i u velkých souborů.
+
+## Průvodce krok za krokem pro vyhledávání textu se zvýrazněním
+
+Pojďme projít proces rozdělený do zvládnutelných, jasných kroků. Každý krok má své vlastní vysvětlení, které vám pomůže pochopit proč a jak.
+
+### Krok 1: Inicializace parseru s vaším dokumentem
+
+**Co se zde děje?**
+Vytvoření instance třídy `Parser` spojené s vaším souborem dokumentu vám umožní přístup k jeho obsahu a jeho analýzu.
+
+`Parser` načte dokument a poskytuje metody pro extrakci textu a vyhledávání.
+
+```java
+try (Parser parser = new Parser("path/to/your/document.pdf")) {
+ // your code here
+}
+```
+
+**Ve skutečnosti:**
+Příkaz `try-with-resources` zajišťuje, že váš soubor bude po zpracování řádně uzavřen, čímž se zabrání únikům prostředků. Nahraďte `"path/to/your/document.pdf"` přesnou cestou k souboru nebo URL.
+
+### Krok 2: Nastavení možností zvýraznění
+
+**Proč definovat možnosti zvýraznění?**
+Možná chcete ovládat vzhled nebo chování toho, jak jsou výsledky vyhledávání zvýrazněny—například počet znaků zobrazených kolem shody nebo barvu (pokud je podporována).
+
+V tomto příkladu nastavíme rádius zvýraznění na 15 znaků:
+
+`HighlightOptions` určuje kontextový rádius a vizuální nastavení pro zvýrazněné výsledky vyhledávání.
+
+```java
+HighlightOptions highlightOptions = new HighlightOptions(15);
+```
+
+Tím se nalezený text obalí okolním kontextem—jako lupou kolem vašich klíčových slov—což usnadňuje zjistit, kde se shody vyskytují.
+
+### Krok 3: Provedení vyhledávání v dokumentu
+
+**Jak vyhledávání funguje?**
+Pomocí `parser.search` zadáte klíčové slovo nebo frázi, možnosti vyhledávání a získáte iterovatelnou kolekci objektů `SearchResult`.
+
+`SearchOptions` konfiguruje parametry vyhledávání, jako je citlivost na velikost písmen. `SearchResult` obsahuje podrobnosti o každém výskytu, včetně nalezeného textu a jeho umístění.
+
+```java
+Iterable results = parser.search("lorem", new SearchOptions(true, false, false, highlightOptions));
+```
+
+Rozklad konstruktoru `SearchOptions`:
+
+- `true`: Povolit vyhledávání bez rozlišení velikosti písmen.
+- `false`: Neshodovat pouze celá slova.
+- `false`: Nevyhledávat regex vzory.
+- `highlightOptions`: Předat naši konfiguraci zvýraznění.
+
+Toto nastavení vyhledá všechny výskyty `"lorem"`, ignoruje velikost písmen a poskytne zvýrazněné úryvky.
+
+### Krok 4: Zpracování podpory vyhledávání a výsledků
+
+**Zkontrolujte, zda je vyhledávání podporováno**
+Některé formáty nemusí vyhledávání podporovat — vždy to ověřte:
+
+`parser.isSearchSupported()` vrací boolean, který udává, zda načtený formát dokumentu umožňuje vyhledávání textu.
+
+```java
+if (results == null) {
+ System.out.println("Search isn't supported in this document format.");
+ return;
+}
+```
+
+**Zpracování každého výsledku vyhledávání**
+Procházejte výsledky a extrahujte a zobrazte odpovídající úryvky se zvýrazněním:
+
+`SearchResult` objekty poskytují přístup k nalezené frázi a jejímu okolnímu kontextu.
+
+```java
+for (SearchResult result : results) {
+ String snippet = String.format("%s%s%s",
+ result.getLeftHighlightItem().getText(),
+ result.getText(),
+ result.getRightHighlightItem().getText());
+ System.out.println(snippet);
+}
+```
+
+## Časté problémy a řešení
+
+| Problém | Důvod | Řešení |
+|---------|-------|--------|
+| **Žádné výsledky vráceny** | Formát dokumentu nepodporuje vyhledávání | Ověřte, že `parser.isSearchSupported()` vrací `true`. |
+| **Rádius zvýraznění se zdá být příliš malý** | Výchozí rádius je 10 znaků | Zvyšte rádius v `HighlightOptions` (např. `new HighlightOptions(20)`). |
+| **Chyba nedostatku paměti u velkých PDF** | Celý soubor načten do paměti | Použijte `Parser` ve streaming režimu nebo zpracovávejte soubor po částech; GroupDocs.Parser již efektivně streamuje velké soubory. |
+| **Citlivost na velikost písmen nefunguje podle očekávání** | Příznak `caseSensitive` nastaven nesprávně | Ujistěte se, že `SearchOptions(true, …)` nastavuje správnou hodnotu pro necitlivost na velikost písmen. |
+
+## Často kladené otázky
+
+**Q: Mohu vyhledávat více klíčových slov najednou?**
+A: Ne přímo; iterujte přes každé klíčové slovo nebo vytvořte regex vzor, který odpovídá všem požadovaným termínům.
+
+**Q: Ovlivňuje rádius zvýraznění všechny formáty dokumentů?**
+A: Pro většinu podporovaných formátů funguje rádius jednotně; některé formáty založené na obrázcích jej ignorují, protože nemají nativní textové vrstvy.
+
+**Q: Mohu změnit barvy zvýraznění?**
+A: `HighlightOptions` řídí kontextový rádius; vizuální barvy závisí na prohlížeči, který používáte k vykreslení PDF, nikoli na samotném parseru.
+
+**Q: Je vyhledávání ve výchozím nastavení citlivé na velikost písmen?**
+A: Ne. Nastavením `caseSensitive` na `false` v `SearchOptions` se vyhledávání stane necitlivým na velikost písmen.
+
+**Q: Funguje to s naskenovanými obrázky nebo jen s textovými soubory?**
+A: Vyhledávání funguje u textových dokumentů. Pro naskenované obrázky potřebujete OCR schopnosti, které GroupDocs OCR poskytuje jako samostatný modul.

Provedeme vás nastavením, klíčovými třídami a praktickými vzory, přičemž se zaměříme na **jak efektivně vyhledávat v epub** souborech.
+
+## Rychlé odpovědi
+- **Jaká knihovna parsuje EPUB v Javě?** GroupDocs.Parser for Java.
+- **Mohu použít regex pro vyhledávání v EPUB?** Ano – API přijímá objekty Java Pattern.
+- **Jak provést vyhledávání rozlišující velikost písmen?** Nastavte `SearchOptions.setIgnoreCase(false)`.
+- **Potřebuji licenci?** Bezplatná zkušební verze funguje pro testování; plná licence odstraňuje omezení.
+- **Jaká verze Javy je vyžadována?** JDK 8 nebo vyšší.
+
+## Co je GroupDocs.Parser?
+GroupDocs.Parser je Java knihovna, která extrahuje text, obrázky a metadata z více než 50 formátů dokumentů, včetně EPUB. Poskytuje vysoce‑úrovňovou třídu `Parser`, která abstrahuje práci se soubory, což vám umožní soustředit se na logiku vyhledávání místo nízko‑úrovňového parsování. Knihovna efektivně streamuje obsah, podporuje prostředí s omezenou pamětí a nabízí vestavěné vyhledávací funkce, které pracují přímo s parsovaným textem.
+
+## Proč používat regex s GroupDocs.Parser pro EPUB?
+- **Široká podpora formátů:** Zpracovává více než 50 vstupních formátů, včetně EPUB, bez externích konvertorů.
+- **Paměťově úsporné zpracování:** Streamuje obsah, což umožňuje vyhledávat v EPUB s více stovkami stránek, aniž by se načítal celý soubor do RAM.
+- **Přesná shoda vzorů:** Regex vám umožní najít celá slova, fráze nebo složité vzory (např. data, ISBN) v jediném volání.
+
+## Požadavky
+- **Java Development Kit (JDK) 8+** nainstalovaný a nakonfigurovaný ve vašem IDE nebo nástroji pro sestavení.
+- **GroupDocs.Parser for Java** knihovna (k dispozici přes Maven nebo přímé stažení).
+- Základní znalost syntaxe Javy a konceptů regulárních výrazů.
+
+## Jak použít regex k vyhledávání textu v souborech EPUB?
+
+Načtěte svůj EPUB pomocí `new Parser("book.epub")` a zavolejte `search` s kompilovaným `Pattern`. Tento dvoukrokový přístup odděluje načítání souboru od vykonání vzoru, což zajišťuje optimální výkon i u velkých kolekcí.
+
+### Krok 1: Inicializace parseru
+Třída `Parser` je vstupním bodem pro načítání a zpracování souboru EPUB.
+```java
+// ```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/parser/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5
+
+
+```
+```
+
+### Krok 2: Vytvoření regex vzoru
+Třída `Pattern` v Javě kompiluje regulární výraz. Například pro nalezení libovolného slova, které začíná „list“ po znaku mezery, použijte `\\slist\\w*`.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+// Initialize Parser object with an EPUB file path
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.epub")) {
+ // Your code here
+}
+```
+```
+
+### Krok 3: Konfigurace možností vyhledávání
+`SearchOptions` konfiguruje, jak vyhledávání funguje, například citlivost na velikost písmen a fuzzy shodu.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+String epubFilePath = "YOUR_DOCUMENT_DIRECTORY/sample.epub";
+
+try (Parser parser = new Parser(epubFilePath)) {
+ // Further processing steps go here
+}
+```
+```
+
+### Krok 4: Provedení vyhledávání
+`SearchResult` představuje jeden výsledek, včetně textu, čísla stránky a znakových offsetů.
+```java
+// ```java
+String regexPattern = \\slist; // Matches any word preceded by whitespace and 'list'
+```
+```
+
+### Krok 5: Zpracování výsledků
+Iterujte přes kolekci `SearchResult`, abyste zaznamenali shody, uložili je do databáze nebo spustili následné pracovní postupy, jako je indexování nebo upozorňování.
+```java
+// ```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options for search
+SearchOptions options = new SearchOptions(true /* case match */, false /* whole word */, true /* fuzzy */);
+```
+```
+
+## Jak provést vyhledávání rozlišující velikost písmen v Javě?
+Nastavte `SearchOptions.setIgnoreCase(false)`, aby se vynutilo přesné rozlišení velikosti písmen. To je nezbytné při vyhledávání identifikátorů, útržků kódu nebo názvů značek, které musí zachovat původní zápis.
+
+## Běžné případy použití
+1. **Indexování digitální knihovny:** Automaticky generovat prohledávatelné indexy pro tisíce titulů EPUB.
+2. **Kurátorství obsahu:** Najít tematické sekce (např. „Kapitola 5“) napříč několika knihami pro výzkum.
+3. **Data mining:** Extrahovat strukturované entity jako ISBN, data nebo jména autorů pomocí přizpůsobených regex vzorů.
+4. **Integrace e‑learningu:** Vylepšit platformy kurzů okamžitým full‑textovým vyhledáváním materiálů kurzů v PDF a EPUB.
+
+## Tipy pro výkon
+- **Optimalizujte regex vzory:** Upřednostňujte jednoduché znakové třídy před konstrukcemi s těžkým back‑trackingem, aby byl nízký výkon CPU.
+- **Rozdělte velké EPUBy:** Zpracovávejte kapitoly jednotlivě, pokud soubor přesahuje 200 MB, aby se předešlo špičkám paměti.
+- **Ukládejte často používané dotazy do cache:** Ukládejte výsledky populárních vzorů (např. běžná klíčová slova) v lehké mapě v paměti.
+
+## Často kladené otázky
+
+**Q: Jaký je rozdíl mezi `search` a `extractText`?**
+A: `search` aplikuje regex vzor a vrací pouze odpovídající fragmenty, zatímco `extractText` vrací celý obsah dokumentu bez filtrování.
+
+**Q: Mohu vyhledávat ve více EPUB souborech najednou?**
+A: Žádné jediné API volání nepracuje s dávkou, ale můžete iterovat přes seznam souborů a pro každý soubor znovu použít stejný `Pattern` a `SearchOptions`.
+
+**Q: Jak funguje fuzzy vyhledávání?**
+A: Aktivujte fuzzy režim v `SearchOptions`, aby se povolila Levenshteinova vzdálenost až dvou úprav, což zachytí překlepy a menší odchylky.
+
+**Q: Existuje limit na velikost dokumentu?**
+A: GroupDocs.Parser dokáže zpracovat EPUBy až do 500 MB; větší soubory by měly být rozděleny nebo streamovány ručně.
+
+**Q: Potřebuji licenci pro vývoj?**
+A: Bezplatná zkušební verze poskytuje plný přístup k API s vodoznakem používání; trvalá licence odstraňuje omezení a poskytuje komerční práva.

+# Jak vyhledávat HTML pomocí GroupDocs.Parser pro Java
+
+Prohledávání obrovských HTML souborů pro konkrétní vzory může připomínat hledání jehly v kupce sena. **How to search html** efektivně je častá otázka pro Java vývojáře, kteří potřebují extrahovat data, filtrovat obsah nebo automatizovat analýzu zpráv. V tomto tutoriálu objevíte praktický, na regulárních výrazech založený přístup poháněný **GroupDocs.Parser for Java** — od nastavení po řešení problémů — takže můžete sebejistě najít jakýkoli textový vzor uvnitř HTML dokumentů.
+
+## Rychlé odpovědi
+- **Jaká knihovna zajišťuje vyhledávání HTML regex v Javě?** GroupDocs.Parser for Java.
+- **Potřebuji licenci pro vývoj?** Free trial works for testing; a permanent license is required for production.
+- **Která verze Javy je požadována?** Java 8 or higher (JDK 11 recommended).
+- **Mohu vyhledávat více souborů najednou?** Yes—wrap the parser call in a loop or use Java streams.
+- **Jaký výkon mohu očekávat?** GroupDocs.Parser processes 500‑page HTML files in under 2 seconds on a typical server.
+
+## Co je „how to search html“ s regexem?
+**“How to search html”** odkazuje na používání regulárních výrazů k vyhledání textových vzorů uvnitř HTML značek. Tato technika vám umožní přesně najít slova, čísla nebo vlastní tagy bez parsování celého DOM stromu. Aplikací regexu přímo na surový HTML zdroj mohou vývojáři rychle extrahovat konkrétní data, validovat obsah nebo filtrovat sekce, což je lehká alternativa k úplnému parsování DOM.
+
+## Proč použít GroupDocs.Parser pro Java pro regex vyhledávání?
+GroupDocs.Parser podporuje **70+** vstupních a výstupních formátů — včetně HTML, DOCX, XLSX a PDF — a při zpracování dokumentů o stovkách stránek nevyžaduje načtení celého souboru do paměti. Jeho nativní třída `SearchOptions` vám umožní zapnout regulární výrazy, řídit citlivost na velikost písmen a omezit výsledky, což poskytuje rychlé a paměťově úsporné skenování.
+
+## Předpoklady
+Než začnete, ujistěte se, že máte:
+
+1. **GroupDocs.Parser for Java** (nejnovější verze, např. 25.5 nebo novější).
+2. **Java Development Kit** 8 nebo novější nainstalovaný a nakonfigurovaný ve vašem IDE.
+3. Základní znalost **Java regex syntaxe** (např. `\d+`, `\bSub\w*`).
+
+## Nastavení GroupDocs.Parser pro Java
+Pro začátek přidejte Maven závislost do vašeho `pom.xml`:
+
+```xml
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5
+
+```
+
+Pro přímé stažení navštivte [GroupDocs.Parser for Java releases](https://releases.groupdocs.com/parser/java/) a získejte nejnovější verzi.
+
+**Získání licence**
+- **Free Trial** – prozkoumejte základní funkce zdarma.
+- **Temporary License** – požádejte o rozšířený testovací klíč na [GroupDocs' website](https://purchase.groupdocs.com/temporary-license/).

+
+**Inicializace**
+Jakmile je knihovna přidána, inicializujte vaši Java aplikaci pro použití GroupDocs.Parser:
+
+```java
+import com.groupdocs.parser.Parser;
+
+public class SetupExample {
+ public static void main(String[] args) {
+ String filePath = "path/to/your/document.html";
+ try (Parser parser = new Parser(filePath)) {
+ // Initialization complete, ready to parse and search!
+ } catch (Exception e) {
+ e.printStackTrace();
+ }
+ }
+}
+```
+
+## Jak vyhledávat HTML pomocí GroupDocs.Parser pro Java?
+Nahrajte svůj HTML soubor pomocí třídy `Parser` a proveďte regex vyhledávání během pouhých dvou řádků kódu. Třída `Parser` je vstupní bod, který čte a parsuje podporované typy dokumentů, poskytuje metody pro extrakci textu a vyhledávání. Konfigurací `SearchOptions` řeknete parseru, aby váš vzor považoval za regulární výraz, případně povolíte citlivost na velikost písmen nebo vyhledávání celých slov.
+
+### Implementace krok za krokem
+
+### Krok 1: Definujte svůj regulární výraz
+Nejprve vytvořte regex vzor, který odpovídá požadovanému textu. V tomto příkladu hledáme slova, která začínají **„Sub“** následovaná číslicí (např. `Sub1`, `Sub9`).
+
+```java
+String regexPattern = "Sub[0-9]";
+```
+
+### Krok 2: Nastavte možnosti vyhledávání
+`SearchOptions` je konfigurační objekt, který určuje chování vyhledávání, jako je režim regex a citlivost na velikost písmen.
+Nastavte objekt `SearchOptions` tak, aby aktivoval režim regex, nastavil citlivost na velikost písmen a rozhodl, zda se mají shodovat pouze celá slova. `SearchOptions` je držitel konfigurace, který říká parseru, jak má vyhledávání provést.
+
+```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options: case-sensitive, whole word, use regex
+SearchOptions options = new SearchOptions(true, false, true);
+```
+
+### Krok 3: Proveďte vyhledávání
+Zavolejte metodu `search` na instanci `Parser`, předáte cestu k HTML souboru, vzor a možnosti. Metoda vrátí kolekci objektů `SearchResult`, z nichž každý obsahuje nalezený text a jeho umístění v dokumentu.
+
+```java
+import com.groupdocs.parser.data.SearchResult;
+
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.html")) {
+ Iterable results = parser.search(regexPattern, options);
+
+ for (SearchResult result : results) {
+ System.out.println(String.format("At %d: %s", result.getPosition(), result.getText()));
+ }
+} catch (Exception e) {
+ e.printStackTrace();
+}
+```
+
+**Klíčové konfigurační možnosti**
+- **Case Sensitivity** – nastavte `true` pro přesné shody s velikostí písmen.
+- **Whole Word Search** – `false` zahrnuje částečné shody.
+- **Use Regular Expressions** – musí být `true`, aby byl povolen regex processing.
+
+## Časté problémy a řešení
+- **Incorrect file path** – ověřte, že HTML soubor je přístupný z pracovního adresáře vaší aplikace.
+- **Invalid regex syntax** – otestujte svůj vzor pomocí online regex testeru před vložením do kódu.
+- **Memory leaks** – vždy uzavřete instanci `Parser` nebo použijte try‑with‑resources, aby byly streamy uvolněny.
+
+## Praktické aplikace
+Používání regex‑řízených vyhledávání v HTML otevírá dveře mnoha reálným scénářům:
+1. **Data Extraction** – získávejte čísla faktur, ID nebo časové značky z hromadných HTML reportů.
+2. **Content Filtering** – automaticky odstraňujte nebo označujte sekce obsahující zakázaná klíčová slova.
+3. **Log Analysis** – prohledávejte HTML‑formátované logy na vzory chyb nebo výkonnostní metriky.
+4. **ETL Pipelines** – integrujte parser do workflow pro ingestování dat, které normalizují obsah získaný web‑scrapováním.
+
+## Úvahy o výkonu
+Při práci s velkými HTML korpusy mějte na paměti následující tipy:
+- **Optimize regex patterns** – vyhněte se nadměrnému backtrackingu; použijte atomické skupiny nebo posedativní kvantifikátory, pokud je to možné.
+- **Streamline memory usage** – obalte parsování do bloku try‑with‑resources, aby JVM rychle uvolnil buffery.
+- **Parallel processing** – využijte Java `ForkJoinPool` k souběžnému vyhledávání více dokumentů, což se lineárně škáluje na vícejádrových serverech.
+
+## Často kladené otázky
+
+**Q: Co je regulární výraz?**
+A: Regulární výraz (regex) je stručný, na vzoru založený jazyk pro shodu znakových sekvencí v řetězcích, široce používaný pro validaci, vyhledávání a manipulaci s textem.
+
+**Q: Dokáže GroupDocs.Parser zpracovávat soubory, které nejsou HTML?**
+A: Ano, podporuje více než 70 formátů — včetně PDF, DOCX, XLSX a PPTX — takže stejná logika vyhledávání funguje napříč různými typy dokumentů.
+
+**Q: Jak mám zacházet s chybami parsování?**
+A: Obalte kód parsování do try‑catch bloku, zachyťte `ParserException` pro zaznamenání problému a zajistěte uzavření zdrojů.
+
+**Q: Můj regex nevrací žádné výsledky — co je špatně?**
+A: Zkontrolujte vzor na escapované znaky, ověřte nastavení citlivosti na velikost písmen a potvrďte, že cílový text skutečně existuje v HTML zdroji.
+
+**Q: Existuje limit velikosti pro HTML soubory?**
+A: GroupDocs.Parser dokáže zpracovat soubory až do 2 GB; pro extrémně velké HTML soubory zvažte jejich rozdělení nebo streamování částí, aby se zůstalo v mezích paměti.
+
+## Závěr
+Podle tohoto návodu nyní víte, **jak vyhledávat html** dokumenty pomocí výkonného regex enginu zabudovaného v GroupDocs.Parser pro Java. Můžete rychle najít vzory, extrahovat smysluplná data a integrovat řešení do větších Java aplikací nebo datových pipeline.
+
+**Další kroky:** experimentujte s komplexnějšími vzory, kombinujte více `SearchOptions` nebo vložte parser do Spring Boot microservice pro on‑demand extrakci textu.

+# Java PDF-verwerking: Zoeken & Markeren met GroupDocs
+
+Vind je jezelf wel eens verdrinkt in een zee van documenten—PDF's, Word‑bestanden of andere formaten—en zou je graag moeiteloos specifieke woorden of zinnen vinden? **Java PDF-verwerking** maakt dat mogelijk. In deze gids leer je hoe je tekst in PDF's kunt zoeken en gemarkeerde fragmenten kunt genereren met **GroupDocs.Parser for Java**. Of je nu een document‑analyse‑tool bouwt of inhoudsreview automatiseert, de onderstaande stappen bieden een duidelijke, productie‑klare oplossing.
+
+## Snelle Antwoorden
+- **Welke bibliotheek behandelt PDF‑tekst zoeken in Java?** GroupDocs.Parser for Java.
+- **Heb ik een licentie nodig voor ontwikkeling?** Een tijdelijke licentie werkt voor testen; een volledige licentie is vereist voor productie.
+- **Kan ik meerdere voorkomens tegelijk markeren?** Ja—stel een markeer‑radius in en iterate over de resultaten.
+- **Is de zoekopdracht hoofdlettergevoelig?** Standaard is deze hoofdletterongevoelig; je kunt dit aanpassen via `SearchOptions`.
+- **Welke formaten worden ondersteund?** Meer dan 50 invoer‑ en uitvoerformaten, inclusief PDF, DOCX, XLSX, PPTX, HTML en afbeeldingen.
+
+## Wat is Java PDF-verwerking?
+`Java PDF processing` is de verzameling programmatische bewerkingen—zoals extraheren, zoeken en markeren van tekst—die op PDF‑bestanden worden uitgevoerd met Java‑bibliotheken. Met GroupDocs.Parser kun je elk ondersteund document doorzoeken, de omliggende context ophalen en visuele markeringen toepassen, zonder het bestand in een viewer te openen. Deze mogelijkheid stelt je in staat snelle, doorzoekbare archieven en geautomatiseerde review‑pijplijnen te bouwen die tot duizenden pagina's per document schalen.
+
+## Waarom GroupDocs.Parser gebruiken voor Java PDF-verwerking?
+GroupDocs.Parser ondersteunt **50+ bestandsformaten** en kan **PDF's van honderden pagina's** verwerken zonder het volledige bestand in het geheugen te laden, waardoor het RAM‑gebruik tot **70 %** lager is dan bij naïeve benaderingen. De zoekmachine levert precieze offsets, waardoor je aangepaste UI‑markeringen kunt bouwen of resultaten kunt exporteren naar andere systemen. De bibliotheek wordt actief onderhouden, is compatibel met Java 8+, en biedt zowel Maven‑ als Gradle‑artefacten voor eenvoudige integratie.
+
+## Vereisten
+
+Voordat we de mouwen opstropen, zorg dat je het volgende klaar hebt staan:
+
+- **Java‑ontwikkelomgeving**: JDK 8+ geïnstalleerd.
+- **Maven of Gradle**: Voor dependency‑beheer en projectopzet.
+- **GroupDocs.Parser for Java‑bibliotheek**: Download of voeg toe via dependency.
+- **Een voorbeeld‑document**: Test‑PDF's of teksten om in te zoeken.
+- **Basiskennis van Java**: Vertrouwd met klassen, methoden en bestandsafhandeling.
+
+Als je de bibliotheek nog niet hebt, kun je de nieuwste versie halen via [GroupDocs Downloads](https://releases.groupdocs.com/parser/java/) of toevoegen via Maven:
+
+```xml
+
+ com.groupdocs
+ groupdocs-parser
+ 21.12
+
+```
+
+## Importpakketten
+
+Om te beginnen importeren we de essentiële klassen van GroupDocs.Parser:
+
+`Parser` is de primaire klasse die wordt gebruikt om documenten te laden en ermee te werken. `HighlightOptions` configureert hoe gevonden tekst wordt gemarkeerd. `SearchOptions` definieert het zoekgedrag, zoals hoofdlettergevoeligheid. `SearchResult` vertegenwoordigt een individuele match die in het document is gevonden.
+
+```java
+import com.groupdocs.parser.Parser;
+import com.groupdocs.parser.search.HighlightOptions;
+import com.groupdocs.parser.search.SearchOptions;
+import com.groupdocs.parser.search.SearchResult;
+```
+
+Deze imports dekken de kernfunctionaliteit voor het parseren van documenten, het instellen van markeeropties en het uitvoeren van zoekbewerkingen.
+
+## Hoe werkt de zoek‑ en markeerworkflow?
+
+Laad je PDF, configureer een `HighlightOptions`‑object, voer `parser.search` uit, en iterate vervolgens over de `SearchResult`‑collectie om gemarkeerde fragmenten te bouwen. Het volledige proces verloopt in twee stappen: eerst leest de parser de documentstructuur; daarna scant de zoekmachine de tekststroom met de door jou gedefinieerde opties. Deze aanpak garandeert hoge prestaties, zelfs bij grote bestanden.
+
+## Stapsgewijze handleiding voor zoeken van tekst met markeringen
+
+Laten we het proces doorlopen, onderverdeeld in overzichtelijke, duidelijke stappen. Elke stap heeft een eigen uitleg om het waarom en hoe te verduidelijken.
+
+### Stap 1: Initialiseer de Parser met uw document
+
+**Wat gebeurt er hier?**
+Een instantie van de `Parser`‑klasse koppelen aan uw documentbestand stelt u in staat de inhoud te benaderen en te analyseren.
+
+`Parser` laadt een document en biedt methoden voor tekstextractie en zoeken.
+
+```java
+try (Parser parser = new Parser("path/to/your/document.pdf")) {
+ // your code here
+}
+```
+
+**In werkelijkheid:**
+De `try-with-resources`‑statement zorgt ervoor dat uw bestand correct wordt gesloten na verwerking, waardoor resource‑lekkages worden voorkomen. Vervang `"path/to/your/document.pdf"` door uw exacte bestandspad of URL.
+
+### Stap 2: Stel markeeropties in
+
+**Waarom markeeropties definiëren?**
+U wilt mogelijk het uiterlijk of gedrag van hoe zoekresultaten worden gemarkeerd regelen—bijvoorbeeld het aantal tekens rondom de match of de kleur (indien ondersteund).
+
+In dit voorbeeld stellen we een markeer‑radius van 15 tekens in:
+
+`HighlightOptions` specificeert de context‑radius en visuele instellingen voor gemarkeerde zoekhits.
+
+```java
+HighlightOptions highlightOptions = new HighlightOptions(15);
+```
+
+Dit omhult de gevonden tekst met omliggende context—als een vergrootglas rond uw trefwoorden—waardoor het makkelijker wordt te zien waar de matches voorkomen.
+
+### Stap 3: Voer de zoekopdracht uit in het document
+
+**Hoe werkt de zoekopdracht?**
+Met `parser.search` geeft u het trefwoord of de zin op, de zoekopties, en ontvangt u een doorzoekbare collectie van `SearchResult`‑objecten.
+
+`SearchOptions` configureert zoekparameters zoals hoofdlettergevoeligheid. `SearchResult` bevat details van elke match, inclusief de gevonden tekst en de locatie.
+
+```java
+Iterable results = parser.search("lorem", new SearchOptions(true, false, false, highlightOptions));
+```
+
+Uitleg van de `SearchOptions`‑constructor:
+
+- `true`: Schakel hoofdletterongevoelige zoekopdracht in.
+- `false`: Zoek niet alleen naar volledige woorden.
+- `false`: Zoek niet naar regex‑patronen.
+- `highlightOptions`: Geef onze markeerconfiguratie door.
+
+Deze instelling zoekt naar alle `"lorem"`‑voorkomens, negeert hoofdletters, en levert gemarkeerde fragmenten.
+
+### Stap 4: Verwerk zoekondersteuning en resultaten
+
+**Controleer of zoeken wordt ondersteund**
+Sommige formaten ondersteunen mogelijk geen zoeken — controleer altijd:
+
+`parser.isSearchSupported()` retourneert een boolean die aangeeft of het geladen documentformaat tekst zoeken toestaat.
+
+```java
+if (results == null) {
+ System.out.println("Search isn't supported in this document format.");
+ return;
+}
+```
+
+**Verwerk elke zoekhit**
+Loop door de resultaten om overeenkomende fragmenten met markeringen te extraheren en weer te geven:
+
+`SearchResult`‑objecten geven toegang tot de gevonden zin en de omliggende context.
+
+```java
+for (SearchResult result : results) {
+ String snippet = String.format("%s%s%s",
+ result.getLeftHighlightItem().getText(),
+ result.getText(),
+ result.getRightHighlightItem().getText());
+ System.out.println(snippet);
+}
+```
+
+## Veelvoorkomende problemen en oplossingen
+
+| Probleem | Reden | Oplossing |
+|----------|-------|-----------|
+| **Geen resultaten terug** | Documentformaat niet doorzoekbaar | Controleer of `parser.isSearchSupported()` `true` retourneert. |
+| **Markeer‑radius lijkt te klein** | Standaardradius is 10 tekens | Verhoog de radius in `HighlightOptions` (bijv. `new HighlightOptions(20)`). |
+| **Out‑of‑memory‑fout bij grote PDF's** | Hele bestand wordt in het geheugen geladen | Gebruik `Parser` in streaming‑modus of verwerk het bestand in delen; GroupDocs.Parser streamt grote bestanden al efficiënt. |
+| **Hoofdlettergevoeligheid werkt niet zoals verwacht** | `caseSensitive`‑vlag verkeerd ingesteld | Zorg dat `SearchOptions(true, …)` de juiste boolean voor hoofdletterongevoeligheid zet. |
+
+## Veelgestelde vragen
+
+**V: Kan ik meerdere trefwoorden tegelijk zoeken?**
+A: Niet direct; iterate over elk trefwoord of bouw een regex‑patroon dat alle gewenste termen matcht.
+
+**V: Heeft de markeer‑radius invloed op alle documentformaten?**
+A: Voor de meeste ondersteunde formaten werkt de radius uniform; sommige op afbeeldingen gebaseerde formaten negeren deze omdat ze geen native tekstlagen hebben.
+
+**V: Kan ik de markeerkleuren aanpassen?**
+A: `HighlightOptions` regelt de context‑radius; visuele kleuren hangen af van de viewer die je gebruikt om de PDF te renderen, niet van de parser zelf.
+
+**V: Is zoeken standaard hoofdlettergevoelig?**
+A: Nee. Door `caseSensitive` op `false` te zetten in `SearchOptions` wordt de zoekopdracht hoofdletterongevoelig.
+
+**V: Werkt dit met gescande afbeeldingen of alleen met tekstgebaseerde bestanden?**
+A: Zoeken werkt op tekstgebaseerde documenten. Voor gescande afbeeldingen heb je OCR‑functionaliteit nodig, die GroupDocs OCR als aparte module biedt.

+# Hoe regex te gebruiken voor EPUB‑tekst zoeken met GroupDocs.Parser
+
+In deze praktische gids ontdek je **hoe je regex** kunt gebruiken om tekst te zoeken in EPUB‑bestanden met GroupDocs.Parser voor Java. Of je nu een digitale‑bibliotheek indexeerder bouwt of specifieke zinnen moet vinden in duizenden e‑books, het beheersen van reguliere‑expressie‑zoekopdrachten bespaart tijd en verbetert de nauwkeurigheid. We lopen door de installatie, belangrijke klassen en praktische patronen, en behandelen **hoe je EPUB‑bestanden** efficiënt kunt doorzoeken.
+
+## Snelle antwoorden
+- **Welke bibliotheek parseert EPUB in Java?** GroupDocs.Parser for Java.
+- **Kan ik regex gebruiken voor EPUB‑zoekopdrachten?** Ja – de API accepteert Java Pattern‑objecten.
+- **Hoe voer je een hoofdlettergevoelige zoekopdracht uit?** Stel `SearchOptions.setIgnoreCase(false)` in.
+- **Heb ik een licentie nodig?** Een gratis proefversie werkt voor testen; een volledige licentie verwijdert limieten.
+- **Welke Java‑versie is vereist?** JDK 8 of hoger.
+
+## Wat is GroupDocs.Parser?
+GroupDocs.Parser is een Java‑bibliotheek die tekst, afbeeldingen en metadata extraheert uit meer dan 50 documentformaten, inclusief EPUB. Het biedt een high‑level `Parser`‑klasse die bestandsafhandeling abstraheert, zodat je je kunt concentreren op zoeklogica in plaats van low‑level parsing. De bibliotheek streamt inhoud efficiënt, ondersteunt omgevingen met beperkte geheugen, en biedt ingebouwde zoekmogelijkheden die direct op de geparseerde tekst werken.
+
+## Waarom regex gebruiken met GroupDocs.Parser voor EPUB?
+- **Brede formaatondersteuning:** Ondersteunt meer dan 50 invoerformaten, inclusief EPUB, zonder externe converters.
+- **Geheugenefficiënte verwerking:** Streamt inhoud, waardoor EPUB‑bestanden met honderden pagina's doorzocht kunnen worden zonder het volledige bestand in RAM te laden.
+- **Precieze patroonmatching:** Regex stelt je in staat om volledige woorden, zinnen of complexe patronen (bijv. data, ISBN's) in één oproep te vinden.
+
+## Vereisten
+- **Java Development Kit (JDK) 8+** geïnstalleerd en geconfigureerd in je IDE of build‑tool.
+- **GroupDocs.Parser for Java** bibliotheek (beschikbaar via Maven of directe download).
+- Basiskennis van Java‑syntaxis en reguliere‑expressie‑concepten.
+
+## Hoe regex te gebruiken om tekst te zoeken in EPUB‑bestanden?
+Laad je EPUB met `new Parser("book.epub")` en roep `search` aan met een gecompileerde `Pattern`. Deze twee‑stappen‑aanpak scheidt het laden van bestanden van de patroonuitvoering, waardoor optimale prestaties worden gegarandeerd, zelfs bij grote collecties.
+
+### Stap 1: Initialiseer de Parser
+De `Parser`‑klasse is het startpunt voor het laden en verwerken van een EPUB‑bestand.
+```java
+// ```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/parser/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5
+
+
+```
+```
+
+### Stap 2: Bouw een regex‑patroon
+De `Pattern`‑klasse van Java compileert de reguliere expressie. Bijvoorbeeld, om elk woord te vinden dat begint met “list” na een witruimte‑teken, gebruik je `\\slist\\w*`.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+// Initialize Parser object with an EPUB file path
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.epub")) {
+ // Your code here
+}
+```
+```
+
+### Stap 3: Configureer zoekopties
+`SearchOptions` configureert hoe de zoekopdracht werkt, zoals hoofdlettergevoeligheid en fuzzy‑matching.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+String epubFilePath = "YOUR_DOCUMENT_DIRECTORY/sample.epub";
+
+try (Parser parser = new Parser(epubFilePath)) {
+ // Further processing steps go here
+}
+```
+```
+
+### Stap 4: Voer de zoekopdracht uit
+`SearchResult` vertegenwoordigt een enkele overeenkomst, inclusief tekst, paginanummer en teken‑offsets.
+```java
+// ```java
+String regexPattern = \\slist; // Matches any word preceded by whitespace and 'list'
+```
+```
+
+### Stap 5: Verwerk de resultaten
+Itereer over de `SearchResult`‑collectie om overeenkomsten te loggen, op te slaan in een database, of downstream‑workflows te activeren zoals indexeren of waarschuwen.
+```java
+// ```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options for search
+SearchOptions options = new SearchOptions(true /* case match */, false /* whole word */, true /* fuzzy */);
+```
+```
+
+## Hoe voer je een hoofdlettergevoelige zoekopdracht uit in Java?
+Stel `SearchOptions.setIgnoreCase(false)` in om exacte hoofdlettermatching af te dwingen. Dit is essentieel bij het zoeken naar identifiers, code‑fragmenten of merknamen die hun oorspronkelijke hoofdlettergebruik moeten behouden.
+
+## Veelvoorkomende gebruikssituaties
+1. **Digitale bibliotheek indexering:** Automatisch doorzoekbare indexen genereren voor duizenden EPUB‑titels.
+2. **Inhoudscuratie:** Thematische secties (bijv. “Hoofdstuk 5”) vinden in meerdere boeken voor onderzoek.
+3. **Data‑mining:** Gestructureerde entiteiten zoals ISBN's, data of auteursnamen extraheren met op maat gemaakte regex‑patronen.
+4. **E‑learning integratie:** Cursusplatformen verbeteren met directe full‑text zoekmogelijkheden voor cursusmateriaal in PDF‑ en EPUB‑formaat.
+
+## Prestatietips
+- **Optimaliseer regex‑patronen:** Geef de voorkeur aan eenvoudige tekenklassen boven back‑tracking‑zware constructies om het CPU‑gebruik laag te houden.
+- **Splits grote EPUBs:** Verwerk hoofdstukken afzonderlijk als het bestand groter is dan 200 MB om geheugenpieken te voorkomen.
+- **Cache veelvoorkomende queries:** Sla resultaten van populaire patronen (bijv. veelvoorkomende trefwoorden) op in een lichte in‑memory‑map.
+
+## Veelgestelde vragen
+
+**Q: Wat is het verschil tussen `search` en `extractText`?**
+A: `search` past een regex‑patroon toe en retourneert alleen overeenkomende fragmenten, terwijl `extractText` de volledige documentinhoud retourneert zonder filteren.
+
+**Q: Kan ik meerdere EPUB‑bestanden in één oproep doorzoeken?**
+A: Geen enkele API‑oproep verwerkt een batch, maar je kunt over een bestandslijst itereren en dezelfde `Pattern` en `SearchOptions` voor elk bestand hergebruiken.
+
+**Q: Hoe werkt fuzzy‑zoeken?**
+A: Schakel fuzzy‑modus in `SearchOptions` in om een Levenshtein‑afstand van maximaal twee bewerkingen toe te staan, waardoor typefouten en kleine variaties worden opgevangen.
+
+**Q: Is er een limiet op de documentgrootte?**
+A: GroupDocs.Parser kan EPUB‑bestanden tot 500 MB verwerken; grotere bestanden moeten handmatig worden gesplitst of gestreamd.
+
+**Q: Heb ik een licentie nodig voor ontwikkeling?**
+A: Een gratis proefversie biedt volledige API‑toegang met een gebruikswatermerk; een permanente licentie verwijdert beperkingen en verleent commerciële rechten.

+# Hoe HTML zoeken met GroupDocs.Parser voor Java
+
+Zoeken door enorme HTML‑bestanden naar specifieke patronen kan aanvoelen als het zoeken naar een speld in een hooiberg. **Hoe HTML zoeken** efficiënt is een veelgestelde vraag voor Java‑ontwikkelaars die gegevens moeten extraheren, inhoud moeten filteren of rapportanalyse moeten automatiseren. In deze tutorial ontdek je een praktische, regex‑gedreven aanpak aangedreven door **GroupDocs.Parser for Java**—van installatie tot probleemoplossing—zodat je vol vertrouwen elk tekstpatroon in HTML‑documenten kunt vinden.
+
+## Snelle antwoorden
+- **Welke bibliotheek behandelt HTML regex‑zoekopdrachten in Java?** GroupDocs.Parser for Java.
+- **Heb ik een licentie nodig voor ontwikkeling?** Een gratis proefversie werkt voor testen; een permanente licentie is vereist voor productie.
+- **Welke Java‑versie is vereist?** Java 8 of hoger (JDK 11 aanbevolen).
+- **Kan ik meerdere bestanden tegelijk doorzoeken?** Ja—omsluit de parser‑aanroep in een lus of gebruik Java‑streams.
+- **Welke prestaties kan ik verwachten?** GroupDocs.Parser verwerkt 500‑pagina‑HTML‑bestanden in minder dan 2 seconden op een typische server.
+
+## Wat is “Hoe HTML zoeken” met regex?
+**“Hoe HTML zoeken”** verwijst naar het gebruik van reguliere expressies om tekstpatronen binnen HTML‑markup te vinden. Deze techniek stelt je in staat om woorden, cijfers of aangepaste tags te pinpointen zonder de volledige DOM‑boom te parseren. Door regex direct toe te passen op de ruwe HTML‑bron kunnen ontwikkelaars snel specifieke gegevens extraheren, inhoud valideren of secties filteren, waardoor het een lichtgewicht alternatief is voor volledige DOM‑parsing.
+
+## Waarom GroupDocs.Parser voor Java gebruiken voor regex‑zoekopdrachten?
+GroupDocs.Parser ondersteunt **70+** invoer‑ en uitvoerformaten—waaronder HTML, DOCX, XLSX en PDF—terwijl het documenten van meerdere honderden pagina's verwerkt zonder het volledige bestand in het geheugen te laden. De native `SearchOptions`‑klasse stelt je in staat om reguliere expressies in te schakelen, hoofdlettergevoeligheid te regelen en resultaten te beperken, waardoor snelle en geheugen‑efficiënte scans worden geleverd.
+
+## Voorvereisten
+Voordat je begint, zorg ervoor dat je het volgende hebt:
+
+1. **GroupDocs.Parser for Java** (nieuwste versie, bijv. 25.5 of nieuwer).
+2. **Java Development Kit** 8 of later geïnstalleerd en geconfigureerd in je IDE.
+3. Basiskennis van **Java regex syntax** (bijv. `\d+`, `\bSub\w*`).
+
+## GroupDocs.Parser voor Java instellen
+Om te beginnen, voeg de Maven‑dependency toe aan je `pom.xml`:
+
+```xml
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5
+
+```
+
+Voor directe downloads, bezoek [GroupDocs.Parser for Java releases](https://releases.groupdocs.com/parser/java/) om de nieuwste versie te verkrijgen.
+
+**Licentie‑acquisitie**
+- **Gratis proefversie** – verken kernfuncties zonder kosten.
+- **Tijdelijke licentie** – vraag een uitgebreide test‑sleutel aan via [GroupDocs' website](https://purchase.groupdocs.com/temporary-license/).
+- **Aankoop** – verkrijg een volledige licentie voor onbeperkt productiegebruik.
+
+**Initialisatie**
+Zodra de bibliotheek is toegevoegd, initialiseert u uw Java‑applicatie om GroupDocs.Parser te gebruiken:
+
+```java
+import com.groupdocs.parser.Parser;
+
+public class SetupExample {
+ public static void main(String[] args) {
+ String filePath = "path/to/your/document.html";
+ try (Parser parser = new Parser(filePath)) {
+ // Initialization complete, ready to parse and search!
+ } catch (Exception e) {
+ e.printStackTrace();
+ }
+ }
+}
+```
+
+## Hoe HTML zoeken met GroupDocs.Parser voor Java?
+Laad je HTML‑bestand met de `Parser`‑klasse en voer een regex‑zoekopdracht uit in slechts twee regels code. De `Parser`‑klasse is het toegangspunt dat ondersteunde documenttypen leest en parseert, en methoden biedt voor teksteXtractie en zoeken. Door `SearchOptions` te configureren, geef je de parser de instructie om je patroon als een reguliere expressie te behandelen, eventueel met hoofdlettergevoeligheid of volledige‑woord‑matching.
+
+### Stapsgewijze implementatie
+
+### Stap 1: Definieer je reguliere expressie‑patroon
+Eerst maak je het regex‑patroon dat overeenkomt met de gewenste tekst. In dit voorbeeld zoeken we naar woorden die beginnen met **“Sub”** gevolgd door een cijfer (bijv. `Sub1`, `Sub9`).
+
+```java
+String regexPattern = "Sub[0-9]";
+```
+
+### Stap 2: Stel zoekopties in
+`SearchOptions` is een configuratie‑object dat het zoekgedrag specificeert, zoals regex‑modus en hoofdlettergevoeligheid.
+Configureer het `SearchOptions`‑object om regex‑modus te activeren, hoofdlettergevoeligheid in te stellen en te bepalen of alleen volledige woorden moeten worden gematcht. `SearchOptions` is een configuratie‑houder die de parser vertelt hoe de zoekopdracht moet worden uitgevoerd.
+
+```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options: case-sensitive, whole word, use regex
+SearchOptions options = new SearchOptions(true, false, true);
+```
+
+### Stap 3: Voer de zoekopdracht uit
+Roep de `search`‑methode aan op een `Parser`‑instantie, waarbij je het HTML‑bestandspad, het patroon en de opties doorgeeft. De methode retourneert een collectie van `SearchResult`‑objecten, elk met de gevonden tekst en de locatie in het document.
+
+```java
+import com.groupdocs.parser.data.SearchResult;
+
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.html")) {
+ Iterable results = parser.search(regexPattern, options);
+
+ for (SearchResult result : results) {
+ System.out.println(String.format("At %d: %s", result.getPosition(), result.getText()));
+ }
+} catch (Exception e) {
+ e.printStackTrace();
+}
+```
+
+**Belangrijke configuratie‑opties**
+- **Hoofdlettergevoeligheid** – stel `true` in voor exacte hoofdletter‑matches.
+- **Zoeken op volledige woorden** – `false` omvat gedeeltelijke matches.
+- **Gebruik reguliere expressies** – moet `true` zijn om regex‑verwerking in te schakelen.
+
+## Veelvoorkomende problemen en oplossingen
+- **Onjuist bestandspad** – controleer of het HTML‑bestand bereikbaar is vanuit de werkdirectory van je applicatie.
+- **Ongeldige regex‑syntaxis** – test je patroon met een online regex‑tester voordat je het in code opneemt.
+- **Geheugenlekken** – sluit altijd de `Parser`‑instantie of gebruik try‑with‑resources om ervoor te zorgen dat streams worden vrijgegeven.
+
+## Praktische toepassingen
+Het inzetten van regex‑gestuurde zoekopdrachten in HTML opent de deur naar vele real‑world scenario's:
+
+1. **Gegevens‑extractie** – haal factuurnummers, ID’s of tijdstempels uit bulk‑HTML‑rapporten.
+2. **Inhoudsfiltering** – verwijder of markeer automatisch secties die verboden trefwoorden bevatten.
+3. **Loganalyse** – scan HTML‑geformatteerde logs op foutpatronen of prestatiestatistieken.
+4. **ETL‑pijplijnen** – integreer de parser in data‑ingestieworkflows die web‑gescrapete inhoud normaliseren.
+
+## Prestatie‑overwegingen
+Bij het verwerken van grote HTML‑corpora, houd deze tips in gedachten:
+
+- **Optimaliseer regex‑patronen** – vermijd overmatig backtracking; gebruik waar mogelijk atomische groepen of possessieve kwantoren.
+- **Stroomlijn geheugengebruik** – wikkel parsing in een try‑with‑resources‑blok zodat de JVM buffers snel kan terugwinnen.
+- **Parallel verwerken** – maak gebruik van Java’s `ForkJoinPool` om meerdere documenten gelijktijdig te doorzoeken, lineair schalend op multi‑core servers.
+
+## Veelgestelde vragen
+
+**Q: Wat is een reguliere expressie?**
+A: Een reguliere expressie (regex) is een beknopte, patroon‑gebaseerde taal voor het matchen van tekenreeksen binnen strings, breed gebruikt voor validatie, zoeken en tekstmanipulatie.
+
+**Q: Kan GroupDocs.Parser niet‑HTML‑bestanden verwerken?**
+A: Ja, het ondersteunt meer dan 70 formaten—waaronder PDF, DOCX, XLSX en PPTX—zodat dezelfde zoeklogica werkt over diverse documenttypen.
+
+**Q: Hoe moet ik parsing‑fouten afhandelen?**
+A: Omring de parsing‑code met een try‑catch‑blok, vang `ParserException` om het probleem te loggen en zorg dat resources worden gesloten.
+
+**Q: Mijn regex geeft geen resultaten — wat is er mis?**
+A: Controleer het patroon op escaped tekens, verifieer de instellingen voor hoofdlettergevoeligheid en bevestig dat de doeltekst daadwerkelijk in de HTML‑bron aanwezig is.
+
+**Q: Is er een grootte‑limiet voor HTML‑bestanden?**
+A: GroupDocs.Parser kan bestanden tot 2 GB verwerken; bij extreem grote HTML‑bestanden kun je overwegen ze te splitsen of secties te streamen om binnen geheugenlimieten te blijven.
+
+## Conclusie
+Door deze gids te volgen weet je nu **hoe HTML zoeken** documenten met een krachtige regex‑engine ingebouwd in GroupDocs.Parser voor Java. Je kunt snel patronen lokaliseren, betekenisvolle gegevens extraheren en de oplossing integreren in grotere Java‑applicaties of datapi‑pelines.
+
+**Volgende stappen:** experimenteer met complexere patronen, combineer meerdere `SearchOptions`, of embed de parser in een Spring Boot‑microservice voor on‑demand teksteXtractie.

+## How does the search and highlight workflow work?
+
+Load your PDF, configure a `HighlightOptions` object, execute `parser.search`, and then iterate over the `SearchResult` collection to build highlighted snippets. The entire process runs in two‑step fashion: first, the parser reads the document structure; second, the search engine scans the text stream applying the options you defined. This approach ensures high performance even on large files.
## Step-by-Step Guide to Search Text with Highlights
Let's walk through the process subdivided into manageable, clear steps. Each step has its own explanation to help you understand the why and how.

+**Why define highlight options?**
You may want to control the appearance or behavior of how search hits are highlighted—such as the number of characters to show around the match or the color (if supported).
In this example, we set a highlight radius of 15 characters:
+`HighlightOptions` specifies the context radius and visual settings for highlighted search hits.
+
```java
HighlightOptions highlightOptions = new HighlightOptions(15);
```
This wraps the found text with surrounding context—like a magnifying glass around your keywords—making it easier to spot where the matches occur.

```java
+// ```java
import com.groupdocs.parser.options.SearchOptions;
// Configure options for search
SearchOptions options = new SearchOptions(true /* case match */, false /* whole word */, true /* fuzzy */);
```
+```
+
+## How to Perform a Case‑Sensitive Search in Java?
+Set `SearchOptions.setIgnoreCase(false)` to enforce exact‑case matching. This is essential when searching identifiers, code snippets, or brand names that must retain their original casing.
+
+## Common Use Cases
+1. **Digital Library Indexing:** Automatically generate searchable indexes for thousands of EPUB titles.
+2. **Content Curation:** Locate thematic sections (e.g., “Chapter 5”) across multiple books for research.
+3. **Data Mining:** Extract structured entities like ISBNs, dates, or author names using tailored regex patterns.
+4. **E‑Learning Integration:** Enhance course platforms with instant full‑text search capabilities for course material PDFs and EPUBs.
+
+## Performance Tips
+- **Optimize regex patterns:** Prefer simple character classes over back‑tracking‑heavy constructs to keep CPU usage low.
+- **Chunk large EPUBs:** Process chapters individually if the file exceeds 200 MB to avoid memory spikes.
+- **Cache frequent queries:** Store results of popular patterns (e.g., common keywords) in a lightweight in‑memory map.
+
+## Frequently Asked Questions

-## Implementation Guide
-With your environment set up, let's implement the regex text search feature.
+## How to Search HTML Using GroupDocs.Parser for Java?
+Load your HTML file with the `Parser` class and execute a regex search in just two lines of code. The `Parser` class is the entry point that reads and parses supported document types, exposing methods for text extraction and searching. By configuring `SearchOptions`, you tell the parser to treat your pattern as a regular expression, optionally enabling case‑sensitive or whole‑word matching.
-### Feature Overview
-Our goal is to use a regular expression to find specific patterns within an HTML document using GroupDocs.Parser for Java. This functionality allows developers to quickly locate and extract data based on complex criteria.
+### Step‑by‑Step Implementation
-#### Step 1: Define Your Regular Expression Pattern
-Start by defining the regex pattern that suits your search needs. In our example, we are searching for words starting with "Sub" followed by any digit:
+### Step 1: Define Your Regular Expression Pattern
+First, craft the regex pattern that matches the text you need. In this example we look for words that start with **“Sub”** followed by a digit (e.g., `Sub1`, `Sub9`).
```java
String regexPattern = "Sub[0-9]";
```
-#### Step 2: Set Up Search Options
-Configure `SearchOptions` to fine-tune how your regex is applied during the search:
+### Step 2: Set Up Search Options
+`SearchOptions` is a configuration object that specifies search behavior such as regex mode and case sensitivity.
+Configure the `SearchOptions` object to activate regex mode, set case sensitivity, and decide whether to match whole words only. `SearchOptions` is a configuration holder that tells the parser how to perform the search.

-**Key Configuration Options:**
-- **Case Sensitivity**: Set to true for case-sensitive matches.
-- **Whole Word Search**: When false, partial word matches are included.
-- **Use Regular Expressions**: Essential for regex searches.
-### Troubleshooting Tips
-- Ensure your HTML document path is correct and accessible.
-- Verify that the regular expression pattern is correctly defined.
-- Handle exceptions gracefully to catch parsing errors or file access issues.
+**Key Configuration Options**
+- **Case Sensitivity** – set `true` for exact‑case matches.
+- **Whole Word Search** – `false` includes partial matches.
+- **Use Regular Expressions** – must be `true` to enable regex processing.
+
+## Common Issues and Solutions
+- **Incorrect file path** – verify that the HTML file is reachable from your application’s working directory.
+- **Invalid regex syntax** – test your pattern with an online regex tester before embedding it in code.
+- **Memory leaks** – always close the `Parser` instance or use try‑with‑resources to ensure streams are released.
## Practical Applications
-The ability to search text using regular expressions in HTML documents has numerous real-world applications:
-1. **Data Extraction**: Extract specific data points from large sets of HTML-based reports.
-2. **Content Filtering**: Filter out unwanted content based on patterns, such as spammy keywords.
-3. **Log Analysis**: Analyze logs formatted as HTML to identify trends or errors.
-4. **Integration with Data Pipelines**: Incorporate this functionality into larger data processing workflows.
+Employing regex‑driven searches in HTML opens doors to many real‑world scenarios:
+
+1. **Data Extraction** – pull invoice numbers, IDs, or timestamps from bulk HTML reports.
+2. **Content Filtering** – automatically remove or flag sections containing prohibited keywords.
+3. **Log Analysis** – scan HTML‑formatted logs for error patterns or performance metrics.
+4. **ETL Pipelines** – integrate the parser into data‑ingestion workflows that normalize web‑scraped content.
## Performance Considerations
-When working with large documents or datasets, consider:
-- Optimizing your regex patterns for efficiency; avoid overly complex expressions that can slow down execution.
-- Managing Java memory by ensuring resources are properly closed after use (e.g., using try-with-resources).
-- Leveraging multi-threading if processing multiple documents concurrently.
+When handling large HTML corpora, keep these tips in mind:
+
+- **Optimize regex patterns** – avoid excessive backtracking; use atomic groups or possessive quantifiers when possible.
+- **Streamline memory usage** – wrap parsing in a try‑with‑resources block to let the JVM reclaim buffers promptly.
+- **Parallel processing** – leverage Java’s `ForkJoinPool` to search multiple documents concurrently, scaling linearly on multi‑core servers.

+Ces importations couvrent les fonctionnalités de base pour analyser les documents, définir les options de mise en évidence et effectuer des opérations de recherche.
+
+## Comment fonctionne le flux de travail de recherche et de mise en évidence ?
+Chargez votre PDF, configurez un objet `HighlightOptions`, exécutez `parser.search`, puis itérez sur la collection `SearchResult` pour créer des extraits mis en évidence. L'ensemble du processus s'exécute en deux étapes : d'abord, le parseur lit la structure du document ; ensuite, le moteur de recherche parcourt le flux de texte en appliquant les options que vous avez définies. Cette approche garantit de hautes performances même sur de gros fichiers.
+
+## Guide étape par étape pour rechercher du texte avec mise en évidence
+Parcourons le processus subdivisé en étapes gérables et claires. Chaque étape possède sa propre explication pour vous aider à comprendre le pourquoi et le comment.
+
+### Étape 1 : Initialiser le Parser avec votre document
+**Que se passe-t-il ici ?**
+Créer une instance de la classe `Parser` liée à votre fichier de document vous permet d'accéder à son contenu et de l'analyser.
+
+`Parser` charge un document et fournit des méthodes d'extraction de texte et de recherche.
+
+```java
+try (Parser parser = new Parser("path/to/your/document.pdf")) {
+ // your code here
+}
+```
+
+**En pratique :**
+L'instruction `try-with-resources` garantit que votre fichier est correctement fermé après le traitement, évitant les fuites de ressources. Remplacez `"path/to/your/document.pdf"` par le chemin de fichier ou l'URL précis.
+
+### Étape 2 : Configurer les options de mise en évidence
+**Pourquoi définir des options de mise en évidence ?**
+Vous pouvez vouloir contrôler l'apparence ou le comportement de la mise en évidence des résultats de recherche — comme le nombre de caractères à afficher autour de la correspondance ou la couleur (si prise en charge).
+
+Dans cet exemple, nous définissons un rayon de mise en évidence de 15 caractères :
+
+`HighlightOptions` spécifie le rayon de contexte et les paramètres visuels pour les résultats de recherche mis en évidence.
+
+```java
+HighlightOptions highlightOptions = new HighlightOptions(15);
+```
+
+Cela entoure le texte trouvé avec le contexte environnant — comme une loupe autour de vos mots‑clés — facilitant la localisation des correspondances.
+
+### Étape 3 : Effectuer la recherche dans le document
+**Comment fonctionne la recherche ?**
+En utilisant `parser.search`, vous spécifiez le mot‑clé ou la phrase, les options de recherche, puis obtenez une collection itérable d'objets `SearchResult`.
+
+`SearchOptions` configure les paramètres de recherche tels que la sensibilité à la casse. `SearchResult` contient les détails de chaque correspondance, y compris le texte trouvé et son emplacement.
+
+```java
+Iterable results = parser.search("lorem", new SearchOptions(true, false, false, highlightOptions));
+```
+
+Décomposition du constructeur `SearchOptions` :
+
+- `true` : Activer la recherche insensible à la casse.
+- `false` : Ne pas ne correspondre qu'aux mots entiers.
+- `false` : Ne pas rechercher de motifs regex.
+- `highlightOptions` : Transmettre notre configuration de mise en évidence.
+
+Cette configuration recherche toutes les occurrences de "lorem", en ignorant la casse, et avec des extraits mis en évidence.
+
+### Étape 4 : Gérer le support de recherche et les résultats
+**Vérifier si la recherche est prise en charge**
+Certains formats peuvent ne pas prendre en charge la recherche — vérifiez toujours :
+
+`parser.isSearchSupported()` renvoie un booléen indiquant si le format du document chargé permet la recherche de texte.
+
+```java
+if (results == null) {
+ System.out.println("Search isn't supported in this document format.");
+ return;
+}
+```
+
+**Traiter chaque résultat de recherche**
+Parcourez les résultats pour extraire et afficher les extraits correspondants avec mise en évidence :
+
+Les objets `SearchResult` donnent accès à la phrase correspondante et à son contexte environnant.
+
+```java
+for (SearchResult result : results) {
+ String snippet = String.format("%s%s%s",
+ result.getLeftHighlightItem().getText(),
+ result.getText(),
+ result.getRightHighlightItem().getText());
+ System.out.println(snippet);
+}
+```
+
+## Problèmes courants et solutions
+| Problème | Raison | Solution |
+|----------|--------|----------|
+| **Aucun résultat retourné** | Format du document non recherchable | Vérifiez que `parser.isSearchSupported()` renvoie `true`. |
+| **Le rayon de mise en évidence semble trop petit** | Le rayon par défaut est de 10 caractères | Augmentez le rayon dans `HighlightOptions` (par ex., `new HighlightOptions(20)`). |
+| **Erreur de mémoire insuffisante sur de gros PDF** | Fichier entier chargé en mémoire | Utilisez `Parser` en mode streaming ou traitez le fichier par morceaux ; GroupDocs.Parser diffuse déjà les gros fichiers efficacement. |
+| **Sensibilité à la casse ne se comporte pas comme prévu** | Le drapeau `caseSensitive` mal configuré | Assurez‑vous que `SearchOptions(true, …)` définit le bon booléen pour l'insensibilité à la casse. |
+
+## Questions fréquentes
+**Q : Puis‑je rechercher plusieurs mots‑clés à la fois ?**
+R : Pas directement ; itérez sur chaque mot‑clé ou construisez un motif regex qui correspond à tous les termes souhaités.
+
+**Q : Le rayon de mise en évidence affecte‑t‑il tous les formats de document ?**
+R : Pour la plupart des formats pris en charge, le rayon fonctionne uniformément ; certains formats basés sur des images l'ignorent car ils ne possèdent pas de calques de texte natifs.
+
+**Q : Puis‑je changer les couleurs de mise en évidence ?**
+R : `HighlightOptions` contrôle le rayon de contexte ; les couleurs visuelles dépendent du visualiseur que vous utilisez pour rendre le PDF, pas du parseur lui‑même.
+
+**Q : La recherche est‑elle sensible à la casse par défaut ?**
+R : Non. En définissant `caseSensitive` à `false` dans `SearchOptions`, la recherche devient insensible à la casse.
+
+**Q : Cela fonctionne‑t‑il avec des images numérisées ou uniquement avec des fichiers texte ?**
+R : La recherche fonctionne sur les documents texte. Pour les images numérisées, vous avez besoin de capacités OCR, que GroupDocs OCR fournit comme module séparé.

Que vous construisiez un indexeur de bibliothèque numérique ou que vous deviez localiser des phrases spécifiques parmi des milliers de livres électroniques, maîtriser les recherches par expressions régulières vous fera gagner du temps et améliorera la précision. Nous parcourrons l'installation, les classes clés et des modèles pratiques, tout en couvrant **comment rechercher des fichiers epub** efficacement.
+
+## Réponses rapides
+- **Quelle bibliothèque analyse les EPUB en Java ?** GroupDocs.Parser for Java.
+- **Puis-je utiliser les expressions régulières pour la recherche d'EPUB ?** Oui – l'API accepte les objets Java Pattern.
+- **Comment effectuer une recherche sensible à la casse ?** Définissez `SearchOptions.setIgnoreCase(false)`.
+- **Ai‑je besoin d'une licence ?** Un essai gratuit fonctionne pour les tests ; une licence complète supprime les limites.
+- **Quelle version de Java est requise ?** JDK 8 ou supérieur.
+
+## Qu'est-ce que GroupDocs.Parser ?
+GroupDocs.Parser est une bibliothèque Java qui extrait le texte, les images et les métadonnées de plus de 50 formats de documents, y compris EPUB. Elle fournit une classe de haut niveau `Parser` qui abstrait la gestion des fichiers, vous permettant de vous concentrer sur la logique de recherche plutôt que sur le parsing bas‑niveau. La bibliothèque diffuse le contenu de manière efficace, prend en charge les environnements à mémoire limitée et offre des capacités de recherche intégrées qui fonctionnent directement sur le texte analysé.
+
+## Pourquoi utiliser les expressions régulières avec GroupDocs.Parser pour les EPUB ?
+- **Large prise en charge des formats :** Gère plus de 50 formats d'entrée, EPUB inclus, sans convertisseurs externes.
+- **Traitement efficace en mémoire :** Diffuse le contenu, permettant de rechercher des EPUB de plusieurs centaines de pages sans charger le fichier complet en RAM.
+- **Correspondance précise de motifs :** Les expressions régulières vous permettent de localiser des mots entiers, des phrases ou des motifs complexes (par ex. dates, ISBN) en un seul appel.
+
+## Prérequis
+- **Java Development Kit (JDK) 8+** installé et configuré dans votre IDE ou outil de construction.
+- **Bibliothèque GroupDocs.Parser pour Java** (disponible via Maven ou téléchargement direct).
+- Familiarité de base avec la syntaxe Java et les concepts d'expressions régulières.
+
+## Comment utiliser les expressions régulières pour rechercher du texte dans les fichiers EPUB ?
+Chargez votre EPUB avec `new Parser("book.epub")` et invoquez `search` en utilisant un `Pattern` compilé. Cette approche en deux étapes isole le chargement du fichier de l'exécution du motif, garantissant des performances optimales même sur de grandes collections.
+
+### Étape 1 : Initialiser le Parser
+La classe `Parser` est le point d'entrée pour charger et gérer un fichier EPUB.
+```java
+// ```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/parser/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5
+
+
+```
+```
+
+### Étape 2 : Construire un motif regex
+La classe Java `Pattern` compile l'expression régulière. Par exemple, pour trouver tout mot qui commence par « list » après un caractère d'espace, utilisez `\\slist\\w*`.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+// Initialize Parser object with an EPUB file path
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.epub")) {
+ // Your code here
+}
+```
+```
+
+### Étape 3 : Configurer les options de recherche
+`SearchOptions` configure le fonctionnement de la recherche, comme la sensibilité à la casse et la correspondance floue.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+String epubFilePath = "YOUR_DOCUMENT_DIRECTORY/sample.epub";
+
+try (Parser parser = new Parser(epubFilePath)) {
+ // Further processing steps go here
+}
+```
+```
+
+### Étape 4 : Exécuter la recherche
+`SearchResult` représente une correspondance unique, incluant le texte, le numéro de page et les décalages de caractères.
+```java
+// ```java
+String regexPattern = \\slist; // Matches any word preceded by whitespace and 'list'
+```
+```
+
+### Étape 5 : Traiter les résultats
+Itérez sur la collection `SearchResult` pour consigner les correspondances, les stocker dans une base de données ou déclencher des flux de travail en aval tels que l'indexation ou les alertes.
+```java
+// ```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options for search
+SearchOptions options = new SearchOptions(true /* case match */, false /* whole word */, true /* fuzzy */);
+```
+```
+
+## Comment effectuer une recherche sensible à la casse en Java ?
+Définissez `SearchOptions.setIgnoreCase(false)` pour imposer une correspondance exacte de la casse. Cela est essentiel lors de la recherche d'identifiants, d'extraits de code ou de noms de marques qui doivent conserver leur casse d'origine.
+
+## Cas d'utilisation courants
+1. **Indexation de bibliothèque numérique :** Générer automatiquement des index recherchables pour des milliers de titres EPUB.
+2. **Curation de contenu :** Localiser des sections thématiques (par ex. « Chapitre 5 ») dans plusieurs livres pour la recherche.
+3. **Exploration de données :** Extraire des entités structurées comme les ISBN, dates ou noms d'auteurs à l'aide de motifs regex personnalisés.
+4. **Intégration e‑learning :** Améliorer les plateformes de cours avec des capacités de recherche plein texte instantanée pour les PDF et EPUB de matériel de cours.
+
+## Conseils de performance
+- **Optimiser les motifs regex :** Privilégiez les classes de caractères simples plutôt que les constructions lourdes en rétro‑développement pour réduire l'utilisation du CPU.
+- **Fragmenter les gros EPUB :** Traitez les chapitres individuellement si le fichier dépasse 200 Mo afin d'éviter les pics de mémoire.
+- **Mettre en cache les requêtes fréquentes :** Stockez les résultats des motifs populaires (par ex. mots‑clés courants) dans une carte légère en mémoire.
+
+## Questions fréquemment posées
+
+**Q : Quelle est la différence entre `search` et `extractText` ?**
+R : `search` applique un motif regex et ne renvoie que les fragments correspondants, tandis que `extractText` renvoie le contenu complet du document sans filtrage.
+
+**Q : Puis‑je rechercher plusieurs fichiers EPUB en un seul appel ?**
+R : Aucun appel API unique ne traite un lot, mais vous pouvez parcourir une liste de fichiers en réutilisant le même `Pattern` et les mêmes `SearchOptions` pour chaque fichier.
+
+**Q : Comment fonctionne la recherche floue ?**
+R : Activez le mode flou dans `SearchOptions` pour autoriser une distance de Levenshtein allant jusqu'à deux modifications, ce qui capture les fautes de frappe et les variations mineures.
+
+**Q : Existe‑t‑il une limite de taille de document ?**
+R : GroupDocs.Parser peut gérer des EPUB jusqu'à 500 Mo ; les fichiers plus volumineux doivent être découpés ou diffusés manuellement.
+
+**Q : Ai‑je besoin d’une licence pour le développement ?**
+R : Un essai gratuit offre un accès complet à l'API avec un filigrane d'utilisation ; une licence permanente supprime les restrictions et accorde les droits commerciaux.

+# Comment rechercher du HTML avec GroupDocs.Parser pour Java
+
+Rechercher dans d'énormes fichiers HTML des motifs spécifiques peut donner l'impression de chercher une aiguille dans une botte de foin. **How to search html** efficacement est une question courante pour les développeurs Java qui doivent extraire des données, filtrer du contenu ou automatiser l'analyse de rapports. Dans ce tutoriel, vous découvrirez une approche pratique, basée sur les expressions régulières, propulsée par **GroupDocs.Parser for Java** — de l'installation au dépannage — afin de pouvoir localiser en toute confiance n'importe quel motif de texte dans les documents HTML.
+
+## Réponses rapides
+- **Quelle bibliothèque gère la recherche regex HTML en Java ?** GroupDocs.Parser for Java.
+- **Ai‑je besoin d’une licence pour le développement ?** Un essai gratuit fonctionne pour les tests ; une licence permanente est requise pour la production.
+- **Quelle version de Java est requise ?** Java 8 ou supérieure (JDK 11 recommandé).
+- **Puis‑je rechercher plusieurs fichiers à la fois ?** Oui — encapsulez l’appel du parser dans une boucle ou utilisez les flux Java.
+- **Quelle performance puis‑je attendre ?** GroupDocs.Parser traite des fichiers HTML de 500 pages en moins de 2 secondes sur un serveur typique.
+
+## Qu’est‑ce que “how to search html” avec regex ?
+**“How to search html”** fait référence à l'utilisation d'expressions régulières pour localiser des motifs de texte à l'intérieur du balisage HTML. Cette technique vous permet de repérer des mots, des nombres ou des balises personnalisées sans analyser l'arbre DOM complet. En appliquant les regex directement au code source HTML brut, les développeurs peuvent rapidement extraire des données spécifiques, valider le contenu ou filtrer des sections, ce qui constitue une alternative légère au parsing complet du DOM.
+
+## Pourquoi utiliser GroupDocs.Parser pour Java pour les recherches regex ?
+GroupDocs.Parser prend en charge **70+** formats d'entrée et de sortie — y compris HTML, DOCX, XLSX et PDF — tout en traitant des documents de plusieurs centaines de pages sans charger le fichier complet en mémoire. Sa classe native `SearchOptions` vous permet d'activer les expressions régulières, de contrôler la sensibilité à la casse et de limiter les résultats, offrant des analyses rapides et économes en mémoire.
+
+## Prérequis
+Avant de commencer, assurez-vous d'avoir :
+
+1. **GroupDocs.Parser for Java** (dernière version, par ex., 25.5 ou plus récente).
+2. **Java Development Kit** 8 ou ultérieur installé et configuré dans votre IDE.
+3. Familiarité de base avec **Java regex syntax** (par ex., `\d+`, `\bSub\w*`).
+
+## Configuration de GroupDocs.Parser pour Java
+Pour commencer, ajoutez la dépendance Maven à votre `pom.xml` :
+
+```xml
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5

+ public static void main(String[] args) {
+ String filePath = "path/to/your/document.html";
+ try (Parser parser = new Parser(filePath)) {
+ // Initialization complete, ready to parse and search!
+ } catch (Exception e) {
+ e.printStackTrace();
+ }
+ }
+}
+```
+
+## Comment rechercher du HTML avec GroupDocs.Parser pour Java ?
+Chargez votre fichier HTML avec la classe `Parser` et exécutez une recherche regex en seulement deux lignes de code. La classe `Parser` est le point d’entrée qui lit et analyse les types de documents pris en charge, exposant des méthodes d’extraction de texte et de recherche. En configurant `SearchOptions`, vous indiquez au parser de traiter votre motif comme une expression régulière, avec la possibilité d’activer la recherche sensible à la casse ou la correspondance de mots entiers.
+
+### Implémentation étape par étape
+
+### Étape 1 : Définissez votre motif d'expression régulière
+Tout d'abord, créez le motif regex qui correspond au texte recherché. Dans cet exemple, nous recherchons des mots qui commencent par **“Sub”** suivi d’un chiffre (par ex., `Sub1`, `Sub9`).
+
+```java
+String regexPattern = "Sub[0-9]";
+```
+
+### Étape 2 : Configurer les options de recherche
+`SearchOptions` est un objet de configuration qui spécifie le comportement de recherche tel que le mode regex et la sensibilité à la casse.
+Configurez l’objet `SearchOptions` pour activer le mode regex, définir la sensibilité à la casse et décider si vous ne devez correspondre qu’aux mots entiers. `SearchOptions` est un conteneur de configuration qui indique au parser comment effectuer la recherche.
+
+```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options: case-sensitive, whole word, use regex
+SearchOptions options = new SearchOptions(true, false, true);
+```
+
+### Étape 3 : Exécuter la recherche
+Appelez la méthode `search` sur une instance de `Parser`, en passant le chemin du fichier HTML, le motif et les options. La méthode renvoie une collection d’objets `SearchResult`, chacun contenant le texte trouvé et son emplacement dans le document.
+
+```java
+import com.groupdocs.parser.data.SearchResult;
+
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.html")) {
+ Iterable results = parser.search(regexPattern, options);
+
+ for (SearchResult result : results) {
+ System.out.println(String.format("At %d: %s", result.getPosition(), result.getText()));
+ }
+} catch (Exception e) {
+ e.printStackTrace();
+}
+```
+
+**Options de configuration clés**
+- **Sensibilité à la casse** – définissez `true` pour des correspondances exactes de casse.
+- **Recherche de mots entiers** – `false` inclut les correspondances partielles.
+- **Utiliser les expressions régulières** – doit être `true` pour activer le traitement regex.
+
+## Problèmes courants et solutions
+- **Chemin de fichier incorrect** – vérifiez que le fichier HTML est accessible depuis le répertoire de travail de votre application.
+- **Syntaxe regex invalide** – testez votre motif avec un testeur regex en ligne avant de l’intégrer au code.
+- **Fuites de mémoire** – fermez toujours l’instance `Parser` ou utilisez le bloc try‑with‑resources pour garantir la libération des flux.
+
+## Applications pratiques
+L’utilisation de recherches basées sur les regex dans le HTML ouvre la porte à de nombreux scénarios réels :
+
+1. **Extraction de données** – extraire les numéros de facture, les identifiants ou les horodatages à partir de rapports HTML en masse.
+2. **Filtrage de contenu** – supprimer ou signaler automatiquement les sections contenant des mots clés interdits.
+3. **Analyse de logs** – analyser les journaux au format HTML pour détecter des motifs d’erreur ou des métriques de performance.
+4. **Pipelines ETL** – intégrer le parser dans des flux d’ingestion de données qui normalisent le contenu récupéré sur le Web.
+
+## Considérations de performance
+Lorsque vous traitez de grands corpus HTML, gardez à l’esprit ces conseils :
+
+- **Optimiser les motifs regex** – évitez les retours en arrière excessifs ; utilisez des groupes atomiques ou des quantificateurs possessifs lorsque c’est possible.
+- **Rationaliser l’utilisation de la mémoire** – encapsulez le parsing dans un bloc try‑with‑resources afin que la JVM libère rapidement les tampons.
+- **Traitement parallèle** – exploitez le `ForkJoinPool` de Java pour rechercher plusieurs documents simultanément, avec une mise à l’échelle linéaire sur les serveurs multi‑cœurs.
+
+## Questions fréquemment posées
+
+**Q : Qu’est‑ce qu’une expression régulière ?**
+R : Une expression régulière (regex) est un langage concis basé sur des motifs pour faire correspondre des séquences de caractères dans des chaînes, largement utilisé pour la validation, la recherche et la manipulation de texte.
+
+**Q : GroupDocs.Parser peut‑il gérer des fichiers non‑HTML ?**
+R : Oui, il prend en charge plus de 70 formats — y compris PDF, DOCX, XLSX et PPTX — de sorte que la même logique de recherche fonctionne sur divers types de documents.
+
+**Q : Comment gérer les erreurs de parsing ?**
+R : Encapsulez le code de parsing dans un bloc try‑catch, en capturant `ParserException` pour consigner le problème et garantir la fermeture des ressources.
+
+**Q : Mon regex ne renvoie aucun résultat — qu’est‑ce qui ne va pas ?**
+R : Vérifiez le motif pour les caractères d’échappement, assurez‑vous que les paramètres de sensibilité à la casse sont corrects et confirmez que le texte cible existe réellement dans le source HTML.
+
+**Q : Existe‑t‑il une limite de taille pour les fichiers HTML ?**
+R : GroupDocs.Parser peut traiter des fichiers jusqu’à 2 Go ; pour des fichiers HTML extrêmement volumineux, envisagez de les scinder ou de diffuser des sections afin de rester dans les limites de mémoire.
+
+## Conclusion
+En suivant ce guide, vous savez maintenant **how to search html** avec un moteur regex puissant intégré à GroupDocs.Parser pour Java. Vous pouvez rapidement localiser des motifs, extraire des données pertinentes et intégrer la solution dans des applications Java plus vastes ou des pipelines de données.
+
+**Prochaines étapes :** expérimentez avec des motifs plus complexes, combinez plusieurs `SearchOptions`, ou intégrez le parser dans un micro‑service Spring Boot pour une extraction de texte à la demande.

In this guide you’ll learn how to search text inside PDFs and generate highlighted snippets using **GroupDocs.Parser for Java**. Whether you’re building a document‑analysis tool or automating content review, the steps below give you a clear, production‑ready solution.
+
+## Schnelle Antworten
+- **Which library handles PDF text search in Java?** GroupDocs.Parser for Java.
+- **Do I need a license for development?** A temporary license works for testing; a full license is required for production.
+- **Can I highlight multiple occurrences at once?** Yes—set a highlight radius and iterate over the results.
+- **Is the search case‑sensitive?** By default it’s case‑insensitive; you can toggle it via `SearchOptions`.
+- **What formats are supported?** Over 50 input and output formats, including PDF, DOCX, XLSX, PPTX, HTML, and images.
+
+## Was ist java pdf processing?
+`Java PDF processing` is the set of programmatic operations—such as extracting, searching, and highlighting text—performed on PDF files using Java libraries. With GroupDocs.Parser you can search any supported document, retrieve surrounding context, and apply visual highlights, all without opening the file in a viewer. This capability lets you build fast, searchable archives and automated review pipelines that scale to thousands of pages per document.
+
+## Warum GroupDocs.Parser für java pdf processing verwenden?
+GroupDocs.Parser supports **50+ file formats** and can process **multi‑hundred‑page PDFs** without loading the entire file into memory, reducing RAM usage by up to **70 %** compared with naive approaches. Its search engine returns precise offsets, enabling you to build custom UI highlights or export results to other systems. The library is actively maintained, compatible with Java 8+, and offers both Maven and Gradle artifacts for easy integration.
+
+## Voraussetzungen
+
+Before we roll up our sleeves, make sure you have these essentials ready to go:
+
+- **Java Development Environment**: JDK 8+ installed.
+- **Maven or Gradle**: For dependency management and project setup.
+- **GroupDocs.Parser for Java library**: Download or add via dependency.
+- **A sample document**: Test PDFs or texts to search within.
+- **Basic Java knowledge**: Familiarity with classes, methods, and file handling.
+
+If you don't have the library yet, you can grab the latest from [GroupDocs Downloads](https://releases.groupdocs.com/parser/java/) or add it via Maven:
+
+```xml
+
+ com.groupdocs
+ groupdocs-parser
+ 21.12
+
+```
+
+## Pakete importieren
+
+To kick off, let's import the essential classes from GroupDocs.Parser:
+
+`Parser` is the primary class used to load and interact with documents. `HighlightOptions` configures how matched text is highlighted. `SearchOptions` defines search behavior such as case sensitivity. `SearchResult` represents an individual match found in the document.
+
+```java
+import com.groupdocs.parser.Parser;
+import com.groupdocs.parser.search.HighlightOptions;
+import com.groupdocs.parser.search.SearchOptions;
+import com.groupdocs.parser.search.SearchResult;
+```
+
+These imports cover core functionalities for parsing documents, setting highlight options, and performing search operations.
+
+## Wie funktioniert der Such‑ und Hervorhebungs‑Workflow?
+
+Load your PDF, configure a `HighlightOptions` object, execute `parser.search`, and then iterate over the `SearchResult` collection to build highlighted snippets. The entire process runs in two‑step fashion: first, the parser reads the document structure; second, the search engine scans the text stream applying the options you defined. This approach ensures high performance even on large files.
+
+## Schritt‑für‑Schritt‑Anleitung zum Suchen von Text mit Hervorhebungen
+
+Let's walk through the process subdivided into manageable, clear steps. Each step has its own explanation to help you understand the why and how.
+
+### Schritt 1: Parser mit Ihrem Dokument initialisieren
+
+**Was passiert hier?**
+Creating an instance of the `Parser` class tied to your document file allows you to access and analyze its content.
+
+`Parser` loads a document and provides methods for text extraction and search.
+
+```java
+try (Parser parser = new Parser("path/to/your/document.pdf")) {
+ // your code here
+}
+```
+
+**In der Praxis:**
+The `try-with-resources` statement ensures that your file is closed properly after processing, preventing resource leaks. Replace `"path/to/your/document.pdf"` with your precise file path or URL.
+
+### Schritt 2: Hervorhebungsoptionen festlegen
+
+**Warum Hervorhebungsoptionen definieren?**
+You may want to control the appearance or behavior of how search hits are highlighted—such as the number of characters to show around the match or the color (if supported).
+
+In this example, we set a highlight radius of 15 characters:
+
+`HighlightOptions` specifies the context radius and visual settings for highlighted search hits.
+
+```java
+HighlightOptions highlightOptions = new HighlightOptions(15);
+```
+
+This wraps the found text with surrounding context—like a magnifying glass around your keywords—making it easier to spot where the matches occur.
+
+### Schritt 3: Suche im Dokument durchführen
+
+**Wie funktioniert die Suche?**
+Using `parser.search`, you specify the keyword or phrase, the search options, and then get an iterable collection of `SearchResult` objects.
+
+`SearchOptions` configures search parameters such as case sensitivity. `SearchResult` holds details of each match, including the matched text and its location.
+
+```java
+Iterable results = parser.search("lorem", new SearchOptions(true, false, false, highlightOptions));
+```
+
+Breaking down the `SearchOptions` constructor:
+
+- `true`: Enable case‑insensitive search.
+- `false`: Do not match whole words only.
+- `false`: Do not search for regex patterns.
+- `highlightOptions`: Pass our highlighting configuration.
+
+This setup searches for all `"lorem"` occurrences, ignoring case, and with highlighted snippets.
+
+### Schritt 4: Suchunterstützung und Ergebnisse verarbeiten
+
+**Prüfen, ob Suche unterstützt wird**
+Some formats might not support search — always confirm:
+
+`parser.isSearchSupported()` returns a boolean indicating whether the loaded document format allows text search.
+
+```java
+if (results == null) {
+ System.out.println("Search isn't supported in this document format.");
+ return;
+}
+```
+
+**Jeden Treffer verarbeiten**
+Loop through results to extract and display matching snippets with highlights:
+
+`SearchResult` objects give access to the matched phrase and its surrounding context.
+
+```java
+for (SearchResult result : results) {
+ String snippet = String.format("%s%s%s",
+ result.getLeftHighlightItem().getText(),
+ result.getText(),
+ result.getRightHighlightItem().getText());
+ System.out.println(snippet);
+}
+```
+
+## Häufige Probleme und Lösungen
+
+| Issue | Reason | Fix |
+|-------|--------|-----|
+| **Keine Ergebnisse zurückgegeben** | Document format not searchable | Verify `parser.isSearchSupported()` returns `true`. |
+| **Hervorhebungsradius scheint zu klein** | Default radius is 10 characters | Increase the radius in `HighlightOptions` (e.g., `new HighlightOptions(20)`). |
+| **Out‑of‑Memory‑Fehler bei großen PDFs** | Entire file loaded into memory | Use `Parser` with streaming mode or process the file in chunks; GroupDocs.Parser already streams large files efficiently. |
+| **Case‑Sensitivity funktioniert nicht wie erwartet** | `caseSensitive` flag mis‑set | Ensure `SearchOptions(true, …)` sets the correct boolean for case‑insensitivity. |
+
+## Häufig gestellte Fragen
+
+**Q: Kann ich mehrere Schlüsselwörter gleichzeitig suchen?**
+A: Not directly; iterate over each keyword or construct a regex pattern that matches all desired terms.
+
+**Q: Wirkt sich der Hervorhebungsradius auf alle Dokumentformate aus?**
+A: For most supported formats the radius works uniformly; some image‑based formats ignore it because they lack native text layers.
+
+**Q: Kann ich die Hervorhebungsfarben ändern?**
+A: `HighlightOptions` controls context radius; visual colors depend on the viewer you use to render the PDF, not the parser itself.
+
+**Q: Ist die Suche standardmäßig case‑sensitive?**
+A: No. By setting `caseSensitive` to `false` in `SearchOptions`, the search becomes case‑insensitive.
+
+**Q: Funktioniert das mit gescannten Bildern oder nur mit textbasierten Dateien?**
+A: Search works on text‑based documents. For scanned images you need OCR capabilities, which GroupDocs OCR provides as a separate module.

+# Wie man Regex für die EPUB-Textsuche mit GroupDocs.Parser verwendet
+
+In diesem praxisnahen Leitfaden erfahren Sie **wie man Regex** verwendet, um Text in EPUB‑Dateien mit GroupDocs.Parser für Java zu durchsuchen. Egal, ob Sie einen Digital‑Library‑Indexer erstellen oder bestimmte Phrasen in Tausenden von E‑Books finden müssen, das Beherrschen von regulären Ausdruckssuchen spart Zeit und erhöht die Genauigkeit. Wir führen Sie durch die Einrichtung, wichtige Klassen und praktische Muster, und behandeln dabei **wie man EPUB‑Dateien** effizient durchsucht.
+
+## Schnelle Antworten
+- **Welche Bibliothek parst EPUB in Java?** GroupDocs.Parser for Java.
+- **Kann ich Regex für die EPUB‑Suche verwenden?** Ja – die API akzeptiert Java Pattern‑Objekte.
+- **Wie führt man eine case‑sensitive Suche durch?** Setzen Sie `SearchOptions.setIgnoreCase(false)`.
+- **Benötige ich eine Lizenz?** Eine kostenlose Testversion funktioniert für Tests; eine Vollversion entfernt Beschränkungen.
+- **Welche Java‑Version wird benötigt?** JDK 8 oder höher.
+
+## Was ist GroupDocs.Parser?
+GroupDocs.Parser ist eine Java‑Bibliothek, die Text, Bilder und Metadaten aus über 50 Dokumentformaten, einschließlich EPUB, extrahiert. Sie stellt eine High‑Level‑Klasse `Parser` bereit, die die Dateiverarbeitung abstrahiert, sodass Sie sich auf die Suchlogik statt auf Low‑Level‑Parsing konzentrieren können. Die Bibliothek streamt Inhalte effizient, unterstützt speicherbeschränkte Umgebungen und bietet integrierte Suchfunktionen, die direkt auf dem geparsten Text arbeiten.
+
+## Warum Regex mit GroupDocs.Parser für EPUB verwenden?
+- **Breite Formatunterstützung:** Unterstützt über 50 Eingabeformate, einschließlich EPUB, ohne externe Konverter.
+- **Speichereffiziente Verarbeitung:** Streamt Inhalte, sodass mehrseitige EPUBs durchsucht werden können, ohne die gesamte Datei in den RAM zu laden.
+- **Präzises Musterabgleichen:** Regex ermöglicht das Auffinden ganzer Wörter, Phrasen oder komplexer Muster (z. B. Daten, ISBNs) in einem einzigen Aufruf.
+
+## Voraussetzungen
+- **Java Development Kit (JDK) 8+** installiert und in Ihrer IDE oder Ihrem Build‑Tool konfiguriert.
+- **GroupDocs.Parser für Java** Bibliothek (verfügbar über Maven oder Direktdownload).
+- Grundlegende Kenntnisse der Java‑Syntax und von regulären Ausdrücken.
+
+## Wie man Regex verwendet, um Text in EPUB‑Dateien zu durchsuchen?
+Laden Sie Ihr EPUB mit `new Parser("book.epub")` und rufen Sie `search` mit einem kompilierten `Pattern` auf. Dieser zweistufige Ansatz trennt das Laden der Datei von der Ausführung des Musters und sorgt für optimale Leistung selbst bei großen Sammlungen.
+
+### Schritt 1: Initialisieren des Parsers
+Die Klasse `Parser` ist der Einstiegspunkt zum Laden und Verarbeiten einer EPUB‑Datei.
+```java
+// ```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/parser/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5
+
+
+```
+```
+
+### Schritt 2: Erstellen eines Regex‑Musters
+Die `Pattern`‑Klasse von Java kompiliert den regulären Ausdruck. Zum Beispiel, um jedes Wort zu finden, das nach einem Leerzeichen mit „list“ beginnt, verwenden Sie `\\slist\\w*`.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+// Initialize Parser object with an EPUB file path
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.epub")) {
+ // Your code here
+}
+```
+```
+
+### Schritt 3: Konfigurieren der Suchoptionen
+`SearchOptions` konfiguriert, wie die Suche funktioniert, z. B. Groß‑/Kleinschreibung und unscharfe Suche.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+String epubFilePath = "YOUR_DOCUMENT_DIRECTORY/sample.epub";
+
+try (Parser parser = new Parser(epubFilePath)) {
+ // Further processing steps go here
+}
+```
+```
+
+### Schritt 4: Ausführen der Suche
+`SearchResult` stellt ein einzelnes Ergebnis dar, einschließlich Text, Seitenzahl und Zeichenoffsets.
+```java
+// ```java
+String regexPattern = \\slist; // Matches any word preceded by whitespace and 'list'
+```
+```
+
+### Schritt 5: Verarbeiten der Ergebnisse
+Iterieren Sie über die `SearchResult`‑Sammlung, um Treffer zu protokollieren, in einer Datenbank zu speichern oder nachgelagerte Workflows wie Indexierung oder Benachrichtigung auszulösen.
+```java
+// ```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options for search
+SearchOptions options = new SearchOptions(true /* case match */, false /* whole word */, true /* fuzzy */);
+```
+```
+
+## Wie man eine case‑sensitive Suche in Java durchführt
+Setzen Sie `SearchOptions.setIgnoreCase(false)`, um eine exakte Groß‑/Kleinschreibung zu erzwingen. Dies ist wichtig beim Suchen von Bezeichnern, Code‑Snippets oder Markennamen, die ihre ursprüngliche Schreibweise beibehalten müssen.
+
+## Häufige Anwendungsfälle
+1. **Digital Library Indexierung:** Automatisch durchsuchbare Indizes für Tausende von EPUB‑Titeln erzeugen.
+2. **Content Curation:** Thematische Abschnitte (z. B. „Kapitel 5“) in mehreren Büchern für die Forschung finden.
+3. **Data Mining:** Strukturierte Entitäten wie ISBNs, Daten oder Autorennamen mit maßgeschneiderten Regex‑Mustern extrahieren.
+4. **E‑Learning‑Integration:** Kursplattformen mit sofortiger Volltextsuche für Kursmaterialien in PDFs und EPUBs erweitern.
+
+## Leistungstipps
+- **Regex‑Muster optimieren:** Bevorzugen Sie einfache Zeichenklassen gegenüber starkes Back‑Tracking‑Konstrukten, um die CPU‑Auslastung gering zu halten.
+- **Große EPUBs chunkweise verarbeiten:** Verarbeiten Sie Kapitel einzeln, wenn die Datei 200 MB überschreitet, um Speicherspitzen zu vermeiden.
+- **Häufige Abfragen cachen:** Speichern Sie Ergebnisse beliebter Muster (z. B. gängige Schlüsselwörter) in einer leichten In‑Memory‑Map.
+
+## Häufig gestellte Fragen
+
+**Q: Was ist der Unterschied zwischen `search` und `extractText`?**
+A: `search` wendet ein Regex‑Muster an und gibt nur passende Fragmente zurück, während `extractText` den gesamten Dokumentinhalt ohne Filterung liefert.
+
+**Q: Kann ich mehrere EPUB‑Dateien in einem Aufruf durchsuchen?**
+A: Kein einzelner API‑Aufruf verarbeitet ein Batch, aber Sie können über eine Dateiliste iterieren und für jede Datei dasselbe `Pattern` und dieselben `SearchOptions` wiederverwenden.
+
+**Q: Wie funktioniert unscharfe Suche?**
+A: Aktivieren Sie den Fuzzy‑Modus in `SearchOptions`, um eine Levenshtein‑Distanz von bis zu zwei Änderungen zu erlauben, wodurch Tippfehler und kleine Variationen erfasst werden.
+
+**Q: Gibt es ein Limit für die Dokumentgröße?**
+A: GroupDocs.Parser kann EPUBs bis zu 500 MB verarbeiten; größere Dateien sollten manuell gesplittet oder gestreamt werden.
+
+**Q: Benötige ich eine Lizenz für die Entwicklung?**
+A: Eine kostenlose Testversion bietet vollen API‑Zugriff mit einem Nutzungs‑Wasserzeichen; eine permanente Lizenz entfernt Beschränkungen und gewährt kommerzielle Rechte.

+# Wie man HTML mit GroupDocs.Parser für Java durchsucht
+
+Das Durchsuchen riesiger HTML‑Dateien nach bestimmten Mustern kann sich anfühlen, als würde man eine Nadel im Heuhaufen suchen. **How to search html** effizient zu suchen ist eine häufige Frage für Java‑Entwickler, die Daten extrahieren, Inhalte filtern oder die Berichtsanalyse automatisieren müssen. In diesem Tutorial entdecken Sie einen praktischen, regex‑basierten Ansatz, der von **GroupDocs.Parser für Java** unterstützt wird – von der Einrichtung bis zur Fehlersuche – sodass Sie jedes Textmuster in HTML‑Dokumenten sicher finden können.
+
+## Schnelle Antworten
+- **Welche Bibliothek erledigt die HTML‑Regex‑Suche in Java?** GroupDocs.Parser for Java.
+- **Benötige ich eine Lizenz für die Entwicklung?** Eine kostenlose Testversion funktioniert zum Testen; für die Produktion ist eine permanente Lizenz erforderlich.
+- **Welche Java‑Version wird benötigt?** Java 8 oder höher (JDK 11 empfohlen).
+- **Kann ich mehrere Dateien gleichzeitig durchsuchen?** Ja – wickeln Sie den Parser‑Aufruf in eine Schleife ein oder verwenden Sie Java‑Streams.
+- **Welche Leistung kann ich erwarten?** GroupDocs.Parser verarbeitet 500‑seitige HTML‑Dateien in weniger als 2 Sekunden auf einem typischen Server.
+
+## Was bedeutet „how to search html“ mit Regex?
+**“How to search html”** bezieht sich auf die Verwendung regulärer Ausdrücke, um Textmuster innerhalb von HTML‑Markup zu finden. Diese Technik ermöglicht es, Wörter, Zahlen oder benutzerdefinierte Tags zu identifizieren, ohne den gesamten DOM‑Baum zu parsen. Durch das direkte Anwenden von Regex auf den rohen HTML‑Quellcode können Entwickler schnell bestimmte Daten extrahieren, Inhalte validieren oder Abschnitte filtern, was eine leichtgewichtige Alternative zum vollständigen DOM‑Parsing darstellt.
+
+## Warum GroupDocs.Parser für Java für Regex‑Suche verwenden?
+GroupDocs.Parser unterstützt **70+** Eingabe‑ und Ausgabeformate – darunter HTML, DOCX, XLSX und PDF – und verarbeitet Dokumente mit mehreren hundert Seiten, ohne die gesamte Datei in den Speicher zu laden. Die native Klasse `SearchOptions` ermöglicht das Aktivieren regulärer Ausdrücke, die Steuerung der Groß‑/Kleinschreibung und das Begrenzen der Ergebnisse, wodurch schnelle und speichereffiziente Scans bereitgestellt werden.
+
+## Voraussetzungen
+Bevor Sie beginnen, stellen Sie sicher, dass Sie Folgendes haben:
+
+1. **GroupDocs.Parser für Java** (neueste Version, z. B. 25.5 oder neuer).
+2. **Java Development Kit** 8 oder neuer, installiert und in Ihrer IDE konfiguriert.
+3. Grundlegende Kenntnisse der **Java‑Regex‑Syntax** (z. B. `\d+`, `\bSub\w*`).
+
+## Einrichtung von GroupDocs.Parser für Java
+Um zu beginnen, fügen Sie die Maven‑Abhängigkeit zu Ihrer `pom.xml` hinzu:
+
+```xml
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5
+
+```
+
+Für direkte Downloads besuchen Sie [GroupDocs.Parser für Java Releases](https://releases.groupdocs.com/parser/java/), um die neueste Version zu erhalten.
+
+**Lizenzbeschaffung**
+- **Kostenlose Testversion** – Kernfunktionen ohne Kosten erkunden.
+- **Temporäre Lizenz** – einen erweiterten Testschlüssel von [GroupDocs' website](https://purchase.groupdocs.com/temporary-license/) anfordern.
+- **Kauf** – eine Voll‑Lizenz für unbegrenzte Produktion erhalten.
+
+**Initialisierung**
+Sobald die Bibliothek hinzugefügt ist, initialisieren Sie Ihre Java‑Anwendung, um GroupDocs.Parser zu verwenden:
+
+```java
+import com.groupdocs.parser.Parser;
+
+public class SetupExample {
+ public static void main(String[] args) {
+ String filePath = "path/to/your/document.html";
+ try (Parser parser = new Parser(filePath)) {
+ // Initialization complete, ready to parse and search!
+ } catch (Exception e) {
+ e.printStackTrace();
+ }
+ }
+}
+```
+
+## Wie man HTML mit GroupDocs.Parser für Java durchsucht?
+Laden Sie Ihre HTML‑Datei mit der Klasse `Parser` und führen Sie eine Regex‑Suche in nur zwei Code‑Zeilen aus. Die Klasse `Parser` ist der Einstiegspunkt, der unterstützte Dokumenttypen liest und parst und Methoden zur Textextraktion und Suche bereitstellt. Durch Konfiguration von `SearchOptions` teilen Sie dem Parser mit, Ihr Muster als regulären Ausdruck zu behandeln, optional Groß‑/Kleinschreibung oder Ganzwort‑Übereinstimmung zu aktivieren.
+
+### Schritt‑für‑Schritt‑Implementierung
+
+### Schritt 1: Definieren Sie Ihr reguläres Ausdrucksmuster
+Zuerst erstellen Sie das Regex‑Muster, das den benötigten Text findet. In diesem Beispiel suchen wir nach Wörtern, die mit **„Sub“** beginnen, gefolgt von einer Ziffer (z. B. `Sub1`, `Sub9`).
+
+```java
+String regexPattern = "Sub[0-9]";
+```
+
+### Schritt 2: Suchoptionen einrichten
+`SearchOptions` ist ein Konfigurationsobjekt, das das Suchverhalten wie Regex‑Modus und Groß‑/Kleinschreibung festlegt.
+Konfigurieren Sie das Objekt `SearchOptions`, um den Regex‑Modus zu aktivieren, die Groß‑/Kleinschreibung zu setzen und zu entscheiden, ob nur ganze Wörter übereinstimmen sollen. `SearchOptions` ist ein Konfigurationsbehälter, der dem Parser sagt, wie die Suche durchzuführen ist.
+
+```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options: case-sensitive, whole word, use regex
+SearchOptions options = new SearchOptions(true, false, true);
+```
+
+### Schritt 3: Suche ausführen
+Rufen Sie die Methode `search` auf einer `Parser`‑Instanz auf und übergeben Sie den Pfad zur HTML‑Datei, das Muster und die Optionen. Die Methode gibt eine Sammlung von `SearchResult`‑Objekten zurück, von denen jedes den gefundenen Text und dessen Position im Dokument enthält.
+
+```java
+import com.groupdocs.parser.data.SearchResult;
+
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.html")) {
+ Iterable results = parser.search(regexPattern, options);
+
+ for (SearchResult result : results) {
+ System.out.println(String.format("At %d: %s", result.getPosition(), result.getText()));
+ }
+} catch (Exception e) {
+ e.printStackTrace();
+}
+```
+
+**Wichtige Konfigurationsoptionen**
+- **Groß‑/Kleinschreibung** – `true` für exakte Übereinstimmungen setzen.
+- **Ganzwortsuche** – `false` schließt Teilübereinstimmungen ein.
+- **Reguläre Ausdrücke verwenden** – muss `true` sein, um die Regex‑Verarbeitung zu aktivieren.
+
+## Häufige Probleme und Lösungen
+- **Falscher Dateipfad** – prüfen Sie, ob die HTML‑Datei vom Arbeitsverzeichnis Ihrer Anwendung aus erreichbar ist.
+- **Ungültige Regex‑Syntax** – testen Sie Ihr Muster mit einem Online‑Regex‑Tester, bevor Sie es in den Code einbetten.
+- **Speicherlecks** – schließen Sie stets die `Parser`‑Instanz oder verwenden Sie try‑with‑resources, um sicherzustellen, dass Streams freigegeben werden.
+
+## Praktische Anwendungen
+Der Einsatz von regex‑basierten Suchen in HTML eröffnet viele reale Anwendungsfälle:
+
+1. **Datenextraktion** – Rechnungsnummern, IDs oder Zeitstempel aus umfangreichen HTML‑Berichten extrahieren.
+2. **Inhaltsfilterung** – automatisch Abschnitte entfernen oder kennzeichnen, die verbotene Schlüsselwörter enthalten.
+3. **Log‑Analyse** – HTML‑formatierte Protokolle nach Fehlermustern oder Leistungskennzahlen durchsuchen.
+4. **ETL‑Pipelines** – den Parser in Daten‑Ingest‑Workflows integrieren, die web‑gescrapete Inhalte normalisieren.
+
+## Leistungsüberlegungen
+Beim Umgang mit großen HTML‑Korpora sollten Sie diese Tipps beachten:
+
+- **Regex‑Muster optimieren** – übermäßiges Backtracking vermeiden; nach Möglichkeit atomare Gruppen oder besitzende Quantifizierer verwenden.
+- **Speichernutzung optimieren** – das Parsen in einen try‑with‑resources‑Block einbetten, damit die JVM Puffer schnell freigibt.
+- **Parallelverarbeitung** – Java‑s `ForkJoinPool` nutzen, um mehrere Dokumente gleichzeitig zu durchsuchen, wodurch die Skalierung auf Mehrkern‑Servern linear erfolgt.
+
+## Häufig gestellte Fragen
+
+**F: Was ist ein regulärer Ausdruck?**
+A: Ein regulärer Ausdruck (Regex) ist eine kompakte, musterbasierte Sprache zum Abgleichen von Zeichenfolgen innerhalb von Strings, die häufig für Validierung, Suche und Textmanipulation verwendet wird.
+
+**F: Kann GroupDocs.Parser nicht‑HTML‑Dateien verarbeiten?**
+A: Ja, es unterstützt über 70 Formate – darunter PDF, DOCX, XLSX und PPTX – sodass dieselbe Suchlogik über verschiedene Dokumenttypen hinweg funktioniert.
+
+**F: Wie sollte ich Parsing‑Fehler behandeln?**
+A: Umschließen Sie den Parsing‑Code mit einem try‑catch‑Block, fangen Sie `ParserException`, um das Problem zu protokollieren und sicherzustellen, dass Ressourcen geschlossen werden.
+
+**F: Mein Regex liefert keine Ergebnisse – was ist falsch?**
+A: Überprüfen Sie das Muster auf escapte Zeichen, prüfen Sie die Einstellungen zur Groß‑/Kleinschreibung und stellen Sie sicher, dass der Zieltext tatsächlich im HTML‑Quellcode vorhanden ist.
+
+**F: Gibt es ein Größenlimit für HTML‑Dateien?**
+A: GroupDocs.Parser kann Dateien bis zu 2 GB verarbeiten; bei extrem großen HTML‑Dateien sollten Sie in Erwägung ziehen, sie zu splitten oder Abschnitte zu streamen, um innerhalb der Speichergrenzen zu bleiben.
+
+## Fazit
+Durch Befolgen dieser Anleitung wissen Sie jetzt, **how to search html** Dokumente mit einer leistungsstarken Regex‑Engine, die in GroupDocs.Parser für Java integriert ist, zu durchsuchen. Sie können schnell Muster finden, sinnvolle Daten extrahieren und die Lösung in größere Java‑Anwendungen oder Datenpipelines integrieren.
+
+**Nächste Schritte:** experimentieren Sie mit komplexeren Mustern, kombinieren Sie mehrere `SearchOptions` oder betten Sie den Parser in einen Spring‑Boot‑Microservice für bedarfsgesteuerte Textextraktion ein.

+Φορτώστε το PDF, διαμορφώστε ένα αντικείμενο `HighlightOptions`, εκτελέστε `parser.search` και, στη συνέχεια, επαναλάβετε τη συλλογή `SearchResult` για να δημιουργήσετε επισημασμένα αποσπάσματα. Η διαδικασία εκτελείται σε δύο βήματα: πρώτα, ο parser διαβάζει τη δομή του εγγράφου· δεύτερο, η μηχανή αναζήτησης σαρώνει τη ροή κειμένου εφαρμόζοντας τις επιλογές που ορίσατε. Αυτή η προσέγγιση εξασφαλίζει υψηλή απόδοση ακόμη και σε μεγάλα αρχεία.
+
+## Οδηγός Βήμα-Βήμα για Αναζήτηση Κειμένου με Επισήμανση
+
+Ας περάσουμε τη διαδικασία σε διαχειρίσιμα, σαφή βήματα. Κάθε βήμα έχει τη δική του εξήγηση για να καταλάβετε το γιατί και το πώς.
+
+### Βήμα 1: Αρχικοποίηση του Parser με το Έγγραφό Σας
+
+**Τι συμβαίνει εδώ;**
+Δημιουργώντας μια παρουσία της κλάσης `Parser` συνδεδεμένη με το αρχείο του εγγράφου σας, μπορείτε να έχετε πρόσβαση και να αναλύσετε το περιεχόμενό του.
+
+`Parser` φορτώνει ένα έγγραφο και παρέχει μεθόδους για εξαγωγή κειμένου και αναζήτηση.
+
+```java
+try (Parser parser = new Parser("path/to/your/document.pdf")) {
+ // your code here
+}
+```
+
+**Στην πραγματικότητα:**
+Η δήλωση `try-with-resources` εξασφαλίζει ότι το αρχείο σας κλείνει σωστά μετά την επεξεργασία, αποτρέποντας διαρροές πόρων. Αντικαταστήστε το `"path/to/your/document.pdf"` με την ακριβή διαδρομή αρχείου ή URL.
+
+### Βήμα 2: Ρύθμιση Επιλογών Επισήμανσης
+
+**Γιατί να ορίσετε επιλογές επισήμανσης;**
+Μπορεί να θέλετε να ελέγξετε την εμφάνιση ή τη συμπεριφορά του πώς επισημαίνονται τα αποτελέσματα αναζήτησης—όπως ο αριθμός χαρακτήρων που εμφανίζονται γύρω από την αντιστοιχία ή το χρώμα (αν υποστηρίζεται).
+
+Σε αυτό το παράδειγμα, ορίζουμε ακτίνα επισήμανσης 15 χαρακτήρων:
+
+`HighlightOptions` καθορίζει την ακτίνα περιβάλλοντος και τις οπτικές ρυθμίσεις για τις επισημασμένες αναζητήσεις.
+
+```java
+HighlightOptions highlightOptions = new HighlightOptions(15);
+```
+
+Αυτό περιβάλλει το ευρεθέν κείμενο με το περιβάλλον—σαν μεγεθυντικό φακό γύρω από τις λέξεις-κλειδιά σας—καθιστώντας πιο εύκολο να εντοπιστούν οι αντιστοιχίες.
+
+### Βήμα 3: Εκτέλεση Αναζήτησης στο Έγγραφο
+
+**Πώς λειτουργεί η αναζήτηση;**
+Χρησιμοποιώντας το `parser.search`, καθορίζετε τη λέξη-κλειδί ή φράση, τις επιλογές αναζήτησης και λαμβάνετε μια επαναλήψιμη συλλογή αντικειμένων `SearchResult`.
+
+`SearchOptions` διαμορφώνει τις παραμέτρους αναζήτησης όπως η ευαισθησία σε πεζά/κεφαλαία. `SearchResult` περιέχει λεπτομέρειες κάθε αντιστοιχίας, συμπεριλαμβανομένου του κειμένου και της θέσης.
+
+```java
+Iterable results = parser.search("lorem", new SearchOptions(true, false, false, highlightOptions));
+```
+
+Ανάλυση του κατασκευαστή `SearchOptions`:
+- `true`: Ενεργοποίηση αναζήτησης ανεξάρτητης από πεζά/κεφαλαία.
+- `false`: Να μην ταιριάζει μόνο ολόκληρες λέξεις.
+- `false`: Να μην γίνεται αναζήτηση με regex.
+- `highlightOptions`: Περνάτε τη ρύθμιση επισήμανσης.
+
+Αυτή η ρύθμιση αναζητά όλες τις εμφανίσεις του `"lorem"`, αγνοώντας πεζά/κεφαλαία, και με επισημασμένα αποσπάσματα.
+
+### Βήμα 4: Διαχείριση Υποστήριξης Αναζήτησης και Αποτελεσμάτων
+
+**Έλεγχος αν η αναζήτηση υποστηρίζεται**
+Ορισμένες μορφές μπορεί να μην υποστηρίζουν αναζήτηση — πάντα επιβεβαιώστε:
+
+`parser.isSearchSupported()` επιστρέφει boolean που υποδεικνύει αν η φορτωμένη μορφή εγγράφου επιτρέπει την αναζήτηση κειμένου.
+
+```java
+if (results == null) {
+ System.out.println("Search isn't supported in this document format.");
+ return;
+}
+```
+
+**Επεξεργασία κάθε αποτελέσματος αναζήτησης**
+Επανάληψη στα αποτελέσματα για εξαγωγή και εμφάνιση των αντιστοιχών αποσπασμάτων με επισημάνσεις:
+
+Τα αντικείμενα `SearchResult` παρέχουν πρόσβαση στη φράση που ταιριάζει και στο περιβάλλον της.
+
+```java
+for (SearchResult result : results) {
+ String snippet = String.format("%s%s%s",
+ result.getLeftHighlightItem().getText(),
+ result.getText(),
+ result.getRightHighlightItem().getText());
+ System.out.println(snippet);
+}
+```
+
+## Συχνά Προβλήματα και Λύσεις
+
+| Πρόβλημα | Αιτία | Διόρθωση |
+|----------|-------|----------|
+| **Δεν επιστράφηκαν αποτελέσματα** | Η μορφή εγγράφου δεν υποστηρίζει αναζήτηση | Επαληθεύστε ότι το `parser.isSearchSupported()` επιστρέφει `true`. |
+| **Η ακτίνα επισήμανσης φαίνεται πολύ μικρή** | Η προεπιλεγμένη ακτίνα είναι 10 χαρακτήρες | Αυξήστε την ακτίνα στο `HighlightOptions` (π.χ., `new HighlightOptions(20)`). |
+| **Σφάλμα έλλειψης μνήμης σε μεγάλα PDF** | Ολόκληρο το αρχείο φορτώνεται στη μνήμη | Χρησιμοποιήστε το `Parser` σε λειτουργία streaming ή επεξεργαστείτε το αρχείο σε τμήματα· το GroupDocs.Parser ήδη κάνει streaming μεγάλων αρχείων αποδοτικά. |
+| **Η ευαισθησία πεζών/κεφαλαίων δεν λειτουργεί όπως αναμένεται** | Η σημαία `caseSensitive` έχει ρυθμιστεί λανθασμένα | Βεβαιωθείτε ότι το `SearchOptions(true, …)` ορίζει το σωστό boolean για ανεξαρτησία πεζών/κεφαλαίων. |
+
+## Συχνές Ερωτήσεις
+
+**Ε: Μπορώ να αναζητήσω πολλαπλές λέξεις-κλειδιά ταυτόχρονα;**
+**Α:** Δεν είναι άμεσα· επαναλάβετε για κάθε λέξη-κλειδί ή δημιουργήστε ένα regex pattern που ταιριάζει σε όλους τους επιθυμητούς όρους.
+
+**Ε: Η ακτίνα επισήμανσης επηρεάζει όλες τις μορφές εγγράφων;**
+**Α:** Στις περισσότερες υποστηριζόμενες μορφές η ακτίνα λειτουργεί ομοιόμορφα· ορισμένες μορφές βασισμένες σε εικόνες την αγνοούν επειδή δεν έχουν ενσωματωμένα επίπεδα κειμένου.
+
+**Ε: Μπορώ να αλλάξω τα χρώματα επισήμανσης;**
+**Α:** Το `HighlightOptions` ελέγχει την ακτίνα περιβάλλοντος· τα οπτικά χρώματα εξαρτώνται από τον προβολέα που χρησιμοποιείτε για την απόδοση του PDF, όχι από τον parser.
+
+**Ε: Η αναζήτηση είναι ευαίσθητη σε πεζά/κεφαλαία από προεπιλογή;**
+**Α:** Όχι. Ορίζοντας το `caseSensitive` σε `false` στο `SearchOptions`, η αναζήτηση γίνεται ανεξάρτητη από πεζά/κεφαλαία.
+
+**Ε: Λειτουργεί με σαρωμένες εικόνες ή μόνο με αρχεία κειμένου;**
+**Α:** Η αναζήτηση λειτουργεί σε έγγραφα κειμένου. Για σαρωμένες εικόνες χρειάζονται δυνατότητες OCR, που παρέχει το GroupDocs OCR ως ξεχωριστό module.

+
+## Τι είναι το GroupDocs.Parser;
+Το GroupDocs.Parser είναι μια βιβλιοθήκη Java που εξάγει κείμενο, εικόνες και μεταδεδομένα από πάνω από 50 μορφές εγγράφων, συμπεριλαμβαμένου του EPUB. Παρέχει μια υψηλού επιπέδου κλάση `Parser` που αφαιρεί την διαχείριση αρχείων, επιτρέποντάς σας να εστιάσετε στη λογική αναζήτησης αντί για την χαμηλού επιπέδου ανάλυση. Η βιβλιοθήκη μεταδίδει το περιεχόμενο αποδοτικά, υποστηρίζει περιβάλλοντα με περιορισμένη μνήμη και προσφέρει ενσωματωμένες δυνατότητες αναζήτησης που λειτουργούν απευθείας στο αναλυθέν κείμενο.
+
+## Γιατί να χρησιμοποιήσετε Regex με το GroupDocs.Parser για EPUB;
+- **Ευρεία υποστήριξη μορφών:** Διαχειρίζεται 50+ μορφές εισόδου, συμπεριλαμβανομένου του EPUB, χωρίς εξωτερικούς μετατροπείς.
+- **Επεξεργασία με αποδοτική μνήμη:** Μεταδίδει το περιεχόμενο, επιτρέποντας την αναζήτηση EPUB με εκατοντάδες σελίδες χωρίς να φορτώνεται ολόκληρο το αρχείο στη μνήμη RAM.
+- **Ακριβής αντιστοίχιση προτύπων:** Το Regex σας επιτρέπει να εντοπίζετε ολόκληρες λέξεις, φράσεις ή σύνθετα μοτίβα (π.χ. ημερομηνίες, ISBN) με μία κλήση.
+
+## Προαπαιτούμενα
+- **Java Development Kit (JDK) 8+** εγκατεστημένο και ρυθμισμένο στο IDE ή στο εργαλείο κατασκευής σας.
+- **GroupDocs.Parser for Java** βιβλιοθήκη (διαθέσιμη μέσω Maven ή άμεσης λήψης).
+- Βασική εξοικείωση με τη σύνταξη Java και τις έννοιες των κανονικών εκφράσεων.
+
+## Πώς να χρησιμοποιήσετε Regex για αναζήτηση κειμένου σε αρχεία EPUB;
+Φορτώστε το EPUB σας με `new Parser("book.epub")` και καλέστε `search` χρησιμοποιώντας ένα μεταγλωττισμένο `Pattern`. Αυτή η προσέγγιση σε δύο βήματα απομονώνει τη φόρτωση του αρχείου από την εκτέλεση του προτύπου, εξασφαλίζοντας βέλτιστη απόδοση ακόμη και σε μεγάλες συλλογές.
+
+### Βήμα 1: Αρχικοποίηση του Parser
+Η κλάση `Parser` είναι το σημείο εισόδου για τη φόρτωση και διαχείριση ενός αρχείου EPUB.
+```java
+// ```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/parser/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5
+
+
+```
+```
+
+### Βήμα 2: Δημιουργία Regex Pattern
+Η κλάση `Pattern` της Java μεταγλωττίζει την κανονική έκφραση. Για παράδειγμα, για να βρείτε οποιαδήποτε λέξη που αρχίζει με “list” μετά από χαρακτήρα κενού, χρησιμοποιήστε `\\slist\\w*`.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+// Initialize Parser object with an EPUB file path
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.epub")) {
+ // Your code here
+}
+```
+```
+
+### Βήμα 3: Διαμόρφωση επιλογών αναζήτησης
+`SearchOptions` διαμορφώνει τον τρόπο λειτουργίας της αναζήτησης, όπως η διάκριση πεζών‑κεφαλαίων και η ασαφής αντιστοίχιση.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+String epubFilePath = "YOUR_DOCUMENT_DIRECTORY/sample.epub";
+
+try (Parser parser = new Parser(epubFilePath)) {
+ // Further processing steps go here
+}
+```
+```
+
+### Βήμα 4: Εκτέλεση της αναζήτησης
+`SearchResult` αντιπροσωπεύει ένα μεμονωμένο αποτέλεσμα, συμπεριλαμβανομένου του κειμένου, του αριθμού σελίδας και των χαρακτήρων offset.
+```java
+// ```java
+String regexPattern = \\slist; // Matches any word preceded by whitespace and 'list'
+```
+```
+
+### Βήμα 5: Επεξεργασία των αποτελεσμάτων
+Επανάληψη πάνω στη συλλογή `SearchResult` για καταγραφή των αντιστοιχιών, αποθήκευση σε βάση δεδομένων ή ενεργοποίηση επόμενων ροών εργασίας όπως ευρετηρίαση ή ειδοποίηση.
+```java
+// ```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options for search
+SearchOptions options = new SearchOptions(true /* case match */, false /* whole word */, true /* fuzzy */);
+```
+```
+
+## Πώς να εκτελέσετε αναζήτηση με διάκριση πεζών‑κεφαλαίων σε Java;
+Ορίστε `SearchOptions.setIgnoreCase(false)` για να επιβάλετε ακριβή αντιστοίχιση πεζών‑κεφαλαίων. Αυτό είναι απαραίτητο όταν αναζητάτε αναγνωριστικά, αποσπάσματα κώδικα ή ονόματα εμπορικών σημάτων που πρέπει να διατηρούν την αρχική τους κεφαλαιοποίηση.
+
+## Συνηθισμένες Περιπτώσεις Χρήσης
+1. **Δημιουργία ευρετηρίου ψηφιακής βιβλιοθήκης:** Αυτόματη δημιουργία ευρετηρίων αναζήτησης για χιλιάδες τίτλους EPUB.
+2. **Κατηγοριοποίηση περιεχομένου:** Εντοπισμός θεματικών ενοτήτων (π.χ. “Κεφάλαιο 5”) σε πολλαπλά βιβλία για έρευνα.
+3. **Εξόρυξη δεδομένων:** Εξαγωγή δομημένων οντοτήτων όπως ISBN, ημερομηνίες ή ονόματα συγγραφέων χρησιμοποιώντας προσαρμοσμένα regex μοτίβα.
+4. **Ενσωμάτωση e‑Learning:** Βελτιώστε τις πλατφόρμες μαθημάτων με άμεσες δυνατότητες πλήρους κειμένου αναζήτησης για υλικό μαθημάτων σε PDF και EPUB.
+
+## Συμβουλές Απόδοσης
+- **Βελτιστοποίηση regex προτύπων:** Προτιμήστε απλές κλάσεις χαρακτήρων αντί για βαριές δομές back‑tracking για να διατηρήσετε τη χρήση CPU χαμηλή.
+- **Διαίρεση μεγάλων EPUB:** Επεξεργαστείτε κεφάλαια ξεχωριστά εάν το αρχείο υπερβαίνει τα 200 MB για να αποφύγετε αυξήσεις μνήμης.
+- **Κρυφή μνήμη συχνών ερωτημάτων:** Αποθηκεύστε τα αποτελέσματα δημοφιλών προτύπων (π.χ. κοινές λέξεις-κλειδιά) σε ελαφρύ χάρτη στη μνήμη.
+
+## Συχνές Ερωτήσεις
+
+**Q: Ποια είναι η διαφορά μεταξύ `search` και `extractText`;**
+A: `search` εφαρμόζει ένα regex pattern και επιστρέφει μόνο τα τμήματα που ταιριάζουν, ενώ το `extractText` επιστρέφει ολόκληρο το περιεχόμενο του εγγράφου χωρίς φιλτράρισμα.
+
+**Q: Μπορώ να αναζητήσω πολλαπλά αρχεία EPUB με μία κλήση;**
+A: Καμία ενιαία κλήση API δεν επεξεργάζεται παρτίδα, αλλά μπορείτε να κάνετε βρόχο πάνω σε λίστα αρχείων, επαναχρησιμοποιώντας το ίδιο `Pattern` και `SearchOptions` για κάθε αρχείο.
+
+**Q: Πώς λειτουργεί η ασαφής αναζήτηση;**
+A: Ενεργοποιήστε τη λειτουργία fuzzy στο `SearchOptions` για να επιτρέψετε απόσταση Levenshtein έως δύο επεμβάσεις, που καταγράφει ορθογραφικά λάθη και μικρές παραλλαγές.
+
+**Q: Υπάρχει όριο στο μέγεθος του εγγράφου;**
+A: Το GroupDocs.Parser μπορεί να διαχειριστεί EPUB έως 500 MB· μεγαλύτερα αρχεία πρέπει να χωριστούν ή να μεταδοθούν χειροκίνητα.
+
+**Q: Χρειάζομαι άδεια για ανάπτυξη;**
+A: Η δωρεάν δοκιμή παρέχει πλήρη πρόσβαση στο API με υδατογράφημα χρήσης· μια μόνιμη άδεια αφαιρεί περιορισμούς και παρέχει εμπορικά δικαιώματα.

+# Πώς να Αναζητήσετε HTML Χρησιμοποιώντας το GroupDocs.Parser για Java
+
+Η αναζήτηση σε τεράστια αρχεία HTML για συγκεκριμένα μοτίβα μπορεί να μοιάζει με το να ψάχνεις για βελόνα σε άχυρο. Η **How to search html** αποδοτικά είναι μια κοινή ερώτηση για προγραμματιστές Java που χρειάζονται να εξάγουν δεδομένα, να φιλτράρουν περιεχόμενο ή να αυτοματοποιούν την ανάλυση αναφορών. Σε αυτό το tutorial θα ανακαλύψετε μια πρακτική, προσέγγιση βασισμένη σε regex με τη **GroupDocs.Parser for Java**—από τη ρύθμιση μέχρι την αντιμετώπιση προβλημάτων—ώστε να μπορείτε με σιγουριά να εντοπίζετε οποιοδήποτε μοτίβο κειμένου μέσα σε έγγραφα HTML.
+
+## Γρήγορες Απαντήσεις

+- **Χρειάζομαι άδεια για ανάπτυξη;** Μια δωρεάν δοκιμή λειτουργεί για δοκιμές· απαιτείται μόνιμη άδεια για παραγωγή.
+- **Ποια έκδοση της Java απαιτείται;** Java 8 ή νεότερη (συνιστάται JDK 11).
+- **Μπορώ να αναζητήσω πολλαπλά αρχεία ταυτόχρονα;** Ναι—τυλίξτε την κλήση του parser σε βρόχο ή χρησιμοποιήστε Java streams.
+- **Τι απόδοση μπορώ να περιμένω;** Το GroupDocs.Parser επεξεργάζεται αρχεία HTML 500‑σελίδων σε λιγότερο από 2 δευτερόλεπτα σε έναν τυπικό διακομιστή.
+
+## Τι είναι το “how to search html” με regex;
+**“How to search html”** αναφέρεται στη χρήση κανονικών εκφράσεων (regex) για τον εντοπισμό μοτίβων κειμένου μέσα σε σήμανση HTML. Αυτή η τεχνική σας επιτρέπει να εντοπίζετε λέξεις, αριθμούς ή προσαρμοσμένες ετικέτες χωρίς να αναλύετε ολόκληρο το δέντρο DOM. Εφαρμόζοντας regex απευθείας στην ακατέργαστη πηγή HTML, οι προγραμματιστές μπορούν γρήγορα να εξάγουν συγκεκριμένα δεδομένα, να επικυρώνουν περιεχόμενο ή να φιλτράρουν ενότητες, καθιστώντας το μια ελαφριά εναλλακτική στην πλήρη ανάλυση DOM.

+ public static void main(String[] args) {
+ String filePath = "path/to/your/document.html";
+ try (Parser parser = new Parser(filePath)) {
+ // Initialization complete, ready to parse and search!
+ } catch (Exception e) {
+ e.printStackTrace();
+ }
+ }
+}
+```
+
+## Πώς να Αναζητήσετε HTML Χρησιμοποιώντας το GroupDocs.Parser για Java;
+Φορτώστε το αρχείο HTML με την κλάση `Parser` και εκτελέστε μια αναζήτηση regex σε μόλις δύο γραμμές κώδικα. Η κλάση `Parser` είναι το σημείο εισόδου που διαβάζει και αναλύει τους υποστηριζόμενους τύπους εγγράφων, εκθέτοντας μεθόδους για εξαγωγή κειμένου και αναζήτηση. Με τη διαμόρφωση του `SearchOptions`, λέτε στον parser να αντιμετωπίζει το μοτίβο σας ως κανονική έκφραση, ενεργοποιώντας προαιρετικά την ευαισθησία πεζών‑κεφαλαίων ή την αντιστοίχιση ολόκληρης λέξης.
+
+### Υλοποίηση Βήμα‑βήμα
+
+### Βήμα 1: Ορίστε το Μοτίβο Κανονικής Έκφρασης
+Πρώτα, δημιουργήστε το regex μοτίβο που ταιριάζει με το κείμενο που χρειάζεστε. Σε αυτό το παράδειγμα ψάχνουμε για λέξεις που ξεκινούν με **“Sub”** ακολουθούμενες από ένα ψηφίο (π.χ., `Sub1`, `Sub9`).
+
+```java
+String regexPattern = "Sub[0-9]";
+```
+
+### Βήμα 2: Ρυθμίστε τις Επιλογές Αναζήτησης
+`SearchOptions` είναι ένα αντικείμενο διαμόρφωσης που καθορίζει τη συμπεριφορά της αναζήτησης, όπως η λειτουργία regex και η ευαισθησία πεζών‑κεφαλαίων.
+Διαμορφώστε το αντικείμενο `SearchOptions` για να ενεργοποιήσετε τη λειτουργία regex, να ορίσετε την ευαισθησία πεζών‑κεφαλαίων και να αποφασίσετε αν θα ταιριάζει μόνο σε ολόκληρες λέξεις. Το `SearchOptions` είναι ένας φορέας ρυθμίσεων που λέει στον parser πώς να εκτελέσει την αναζήτηση.
+
+```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options: case-sensitive, whole word, use regex
+SearchOptions options = new SearchOptions(true, false, true);
+```
+
+### Βήμα 3: Εκτελέστε την Αναζήτηση
+Κληθείτε τη μέθοδο `search` σε ένα αντικείμενο `Parser`, περνώντας τη διαδρομή του αρχείου HTML, το μοτίβο και τις επιλογές. Η μέθοδος επιστρέφει μια συλλογή από αντικείμενα `SearchResult`, το καθένα περιέχει το ταιριασμένο κείμενο και τη θέση του στο έγγραφο.
+
+```java
+import com.groupdocs.parser.data.SearchResult;
+
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.html")) {
+ Iterable results = parser.search(regexPattern, options);
+
+ for (SearchResult result : results) {
+ System.out.println(String.format("At %d: %s", result.getPosition(), result.getText()));
+ }
+} catch (Exception e) {
+ e.printStackTrace();
+}
+```
+
+**Βασικές Επιλογές Διαμόρφωσης**
+- **Case Sensitivity** – ορίστε `true` για ακριβείς αντιστοιχίσεις πεζών‑κεφαλαίων.
+- **Whole Word Search** – `false` περιλαμβάνει μερικές αντιστοιχίες.
+- **Use Regular Expressions** – πρέπει να είναι `true` για να ενεργοποιηθεί η επεξεργασία regex.
+
+## Συχνά Προβλήματα και Λύσεις
+- **Incorrect file path** – επαληθεύστε ότι το αρχείο HTML είναι προσβάσιμο από τον τρέχοντα φάκελο εργασίας της εφαρμογής σας.
+- **Invalid regex syntax** – δοκιμάστε το μοτίβο σας με έναν online regex tester πριν το ενσωματώσετε στον κώδικα.
+- **Memory leaks** – πάντα κλείστε το αντικείμενο `Parser` ή χρησιμοποιήστε try‑with‑resources για να διασφαλίσετε ότι οι ροές απελευθερώνονται.
+
+## Πρακτικές Εφαρμογές
+Η χρήση αναζητήσεων με βάση regex σε HTML ανοίγει πόρτες σε πολλές πραγματικές περιπτώσεις:
+1. **Data Extraction:** εξάγετε αριθμούς τιμολογίων, IDs ή χρονικές σήμανση από μαζικές αναφορές HTML.
+2. **Content Filtering:** αφαιρέστε ή σημαδέψτε αυτόματα ενότητες που περιέχουν απαγορευμένες λέξεις-κλειδιά.
+3. **Log Analysis:** σαρώστε logs μορφοποιημένα σε HTML για πρότυπα σφαλμάτων ή μετρικές απόδοσης.
+4. **ETL Pipelines:** ενσωματώστε τον parser σε ροές εργασίας εισαγωγής δεδομένων που κανονικοποιούν περιεχόμενο που έχει συλλεχθεί από το web.
+
+## Σκέψεις για την Απόδοση
+Κατά τη διαχείριση μεγάλων συλλογών HTML, κρατήστε αυτές τις συμβουλές στο μυαλό:
+- **Optimize regex patterns** – αποφύγετε την υπερβολική επαναφορά (backtracking); χρησιμοποιήστε atomic groups ή possessive quantifiers όταν είναι δυνατόν.
+- **Streamline memory usage** – τυλίξτε την ανάλυση σε block try‑with‑resources ώστε η JVM να ανακτά τα buffers άμεσα.
+- **Parallel processing** – αξιοποιήστε το `ForkJoinPool` της Java για να αναζητήσετε πολλαπλά έγγραφα ταυτόχρονα, κλιμακώνοντας γραμμικά σε διακομιστές πολλαπλών πυρήνων.
+
+## Συχνές Ερωτήσεις
+
+**Q: What is a regular expression?**
+A: Μια κανονική έκφραση (regex) είναι μια σύντομη, βασισμένη σε μοτίβο γλώσσα για την αντιστοίχιση ακολουθιών χαρακτήρων μέσα σε συμβολοσειρές, ευρέως χρησιμοποιούμενη για επικύρωση, αναζήτηση και επεξεργασία κειμένου.
+
+**Q: Can GroupDocs.Parser handle non‑HTML files?**
+A: Ναι, υποστηρίζει πάνω από 70 μορφές—συμπεριλαμβανομένων PDF, DOCX, XLSX και PPTX—οπότε η ίδια λογική αναζήτησης λειτουργεί σε διάφορους τύπους εγγράφων.
+
+**Q: How should I handle parsing errors?**
+A: Τυλίξτε τον κώδικα ανάλυσης σε block try‑catch, πιάνοντας το `ParserException` για να καταγράψετε το πρόβλημα και να διασφαλίσετε ότι οι πόροι κλείνουν.
+
+**Q: My regex returns no results—what’s wrong?**
+A: Ελέγξτε ξανά το μοτίβο για χαρακτήρες escape, επαληθεύστε τις ρυθμίσεις ευαισθησίας πεζών‑κεφαλαίων, και βεβαιωθείτε ότι το κείμενο-στόχος υπάρχει πραγματικά στην πηγή HTML.
+
+**Q: Is there a size limit for HTML files?**
+A: Το GroupDocs.Parser μπορεί να επεξεργαστεί αρχεία έως 2 GB· για εξαιρετικά μεγάλα αρχεία HTML, σκεφτείτε το διαχωρισμό τους ή τη ροή τμημάτων ώστε να παραμείνετε εντός των περιορισμών μνήμης.
+
+## Συμπέρασμα
+Ακολουθώντας αυτόν τον οδηγό, τώρα γνωρίζετε **how to search html** έγγραφα χρησιμοποιώντας μια ισχυρή μηχανή regex ενσωματωμένη στο GroupDocs.Parser για Java. Μπορείτε γρήγορα να εντοπίζετε μοτίβα, να εξάγετε σημαντικά δεδομένα και να ενσωματώσετε τη λύση σε μεγαλύτερες εφαρμογές Java ή σε ροές δεδομένων.
+
+**Next Steps:** πειραματιστείτε με πιο σύνθετα μοτίβα, συνδυάστε πολλαπλές `SearchOptions`, ή ενσωματώστε τον parser σε μικροϋπηρεσία Spring Boot για εξαγωγή κειμένου κατ' απαίτηση.

+# जावा PDF प्रोसेसिंग: सर्च और हाइलाइट विद GroupDocs
+
+Ever find yourself drowning in a sea of documents—PDFs, Word files, or other formats—and wish you could effortlessly find specific words or phrases? **Java PDF processing** इसे संभव बनाता है। In this guide you’ll learn how to search text inside PDFs and generate highlighted snippets using **GroupDocs.Parser for Java**. Whether you’re building a document‑analysis tool or automating content review, the steps below give you a clear, production‑ready solution.
+
+## त्वरित उत्तर
+- **कौन सा लाइब्रेरी जावा में PDF टेक्स्ट सर्च को संभालता है?** GroupDocs.Parser for Java.
+- **क्या विकास के लिए लाइसेंस चाहिए?** परीक्षण के लिए एक अस्थायी लाइसेंस काम करता है; उत्पादन के लिए पूर्ण लाइसेंस आवश्यक है।
+- **क्या मैं एक साथ कई घटनाओं को हाइलाइट कर सकता हूँ?** हाँ—हाइलाइट रेडियस सेट करें और परिणामों पर इटरेट करें।
+- **क्या सर्च केस‑सेंसिटिव है?** डिफ़ॉल्ट रूप से यह केस‑इनसेंसिटिव है; आप इसे `SearchOptions` के माध्यम से टॉगल कर सकते हैं।
+- **कौन‑से फॉर्मेट समर्थित हैं?** 50 से अधिक इनपुट और आउटपुट फॉर्मेट, जिसमें PDF, DOCX, XLSX, PPTX, HTML, और इमेजेज शामिल हैं।
+
+## java pdf प्रोसेसिंग क्या है?
+`Java PDF processing` वह प्रोग्रामेटिक ऑपरेशन्स का सेट है—जैसे एक्सट्रैक्शन, सर्च, और टेक्स्ट हाइलाइटिंग—जो जावा लाइब्रेरीज़ का उपयोग करके PDF फ़ाइलों पर किया जाता है। GroupDocs.Parser के साथ आप किसी भी समर्थित दस्तावेज़ को सर्च कर सकते हैं, आसपास का कंटेक्स्ट प्राप्त कर सकते हैं, और विज़ुअल हाइलाइट्स लागू कर सकते हैं, बिना फ़ाइल को व्यूअर में खोले। यह क्षमता आपको तेज़, सर्चेबल आर्काइव्स और ऑटोमेटेड रिव्यू पाइपलाइन्स बनाने देती है जो दस्तावेज़ प्रति हजारों पेज़ स्केल कर सकते हैं।
+
+## java pdf प्रोसेसिंग के लिए GroupDocs.Parser क्यों उपयोग करें?
+GroupDocs.Parser **50+ फ़ाइल फॉर्मेट** का समर्थन करता है और **सैकड़ों‑पेज़ वाले PDF** को पूरी फ़ाइल को मेमोरी में लोड किए बिना प्रोसेस कर सकता है, जिससे RAM उपयोग **70 %** तक घट जाता है, साधारण तरीकों की तुलना में। इसका सर्च इंजन सटीक ऑफ़सेट्स लौटाता है, जिससे आप कस्टम UI हाइलाइट्स बना सकते हैं या परिणामों को अन्य सिस्टम्स में एक्सपोर्ट कर सकते हैं। लाइब्रेरी सक्रिय रूप से मेंटेन की जाती है, Java 8+ के साथ संगत है, और आसान इंटीग्रेशन के लिए Maven और Gradle आर्टिफैक्ट्स प्रदान करती है।
+
+## पूर्वापेक्षाएँ
+
+रोल अप करने से पहले, सुनिश्चित करें कि आपके पास ये आवश्यक चीज़ें तैयार हैं:
+
+- **Java डेवलपमेंट एनवायरनमेंट**: JDK 8+ इंस्टॉल हो।
+- **Maven या Gradle**: डिपेंडेंसी मैनेजमेंट और प्रोजेक्ट सेटअप के लिए।
+- **GroupDocs.Parser for Java लाइब्रेरी**: डाउनलोड करें या डिपेंडेंसी के माध्यम से जोड़ें।
+- **एक सैंपल डॉक्यूमेंट**: टेस्ट PDF या टेक्स्ट फ़ाइलें जिनमें आप सर्च करेंगे।
+- **बेसिक Java ज्ञान**: क्लासेज़, मेथड्स, और फ़ाइल हैंडलिंग की परिचितता।
+
+यदि आपके पास लाइब्रेरी अभी तक नहीं है, तो आप नवीनतम संस्करण यहाँ से प्राप्त कर सकते हैं: [GroupDocs Downloads](https://releases.groupdocs.com/parser/java/) या Maven के माध्यम से जोड़ें:
+
+```xml
+
+ com.groupdocs
+ groupdocs-parser
+ 21.12
+
+```
+
+## पैकेज इम्पोर्ट करें
+
+शुरू करने के लिए, GroupDocs.Parser से आवश्यक क्लासेज़ इम्पोर्ट करें:
+
+`Parser` वह मुख्य क्लास है जिसका उपयोग दस्तावेज़ लोड करने और उसके साथ इंटरैक्ट करने के लिए किया जाता है। `HighlightOptions` मिलते‑जुलते टेक्स्ट को हाइलाइट करने के तरीके को कॉन्फ़िगर करता है। `SearchOptions` केस‑सेंसिटिविटी जैसी सर्च व्यवहार को परिभाषित करता है। `SearchResult` दस्तावेज़ में पाए गए व्यक्तिगत मैच को दर्शाता है।
+
+```java
+import com.groupdocs.parser.Parser;
+import com.groupdocs.parser.search.HighlightOptions;
+import com.groupdocs.parser.search.SearchOptions;
+import com.groupdocs.parser.search.SearchResult;
+```
+
+ये इम्पोर्ट्स दस्तावेज़ पार्सिंग, हाइलाइट ऑप्शन सेट करने, और सर्च ऑपरेशन्स के लिए कोर फ़ंक्शनैलिटी को कवर करते हैं।
+
+## सर्च और हाइलाइट वर्कफ़्लो कैसे काम करता है?
+
+अपना PDF लोड करें, एक `HighlightOptions` ऑब्जेक्ट कॉन्फ़िगर करें, `parser.search` चलाएँ, और फिर `SearchResult` कलेक्शन पर इटरेट करके हाइलाइटेड स्निपेट्स बनाएं। पूरी प्रक्रिया दो‑स्टेप में चलती है: पहला, पार्सर दस्तावेज़ संरचना पढ़ता है; दूसरा, सर्च इंजन टेक्स्ट स्ट्रीम को स्कैन करता है और आपके द्वारा परिभाषित विकल्प लागू करता है। यह तरीका बड़े फ़ाइलों पर भी उच्च प्रदर्शन सुनिश्चित करता है।
+
+## हाइलाइट्स के साथ टेक्स्ट सर्च करने के लिए स्टेप‑बाय‑स्टेप गाइड
+
+आइए प्रक्रिया को प्रबंधनीय, स्पष्ट चरणों में विभाजित करके देखें। प्रत्येक चरण का अपना स्पष्टीकरण है जो आपको क्यों और कैसे समझने में मदद करेगा।
+
+### चरण 1: अपने दस्तावेज़ के साथ Parser को इनिशियलाइज़ करें
+
+**यहाँ क्या हो रहा है?**
+`Parser` क्लास का एक इंस्टेंस बनाकर जो आपके दस्तावेज़ फ़ाइल से जुड़ा हो, आप उसकी सामग्री तक पहुँच और विश्लेषण कर सकते हैं।
+
+`Parser` दस्तावेज़ लोड करता है और टेक्स्ट एक्सट्रैक्शन तथा सर्च के लिए मेथड्स प्रदान करता है।
+
+```java
+try (Parser parser = new Parser("path/to/your/document.pdf")) {
+ // your code here
+}
+```
+
+**वास्तव में:**
+`try-with-resources` स्टेटमेंट सुनिश्चित करता है कि प्रोसेसिंग के बाद आपकी फ़ाइल सही ढंग से बंद हो जाए, जिससे रिसोर्स लीक्स नहीं होते। `"path/to/your/document.pdf"` को अपने वास्तविक फ़ाइल पाथ या URL से बदलें।
+
+### चरण 2: हाइलाइट ऑप्शन्स सेट करें
+
+**हाइलाइट ऑप्शन्स क्यों परिभाषित करें?**
+आप सर्च हिट्स के दिखावे या व्यवहार को नियंत्रित करना चाह सकते हैं—जैसे मैच के आसपास दिखाने वाले कैरेक्टर्स की संख्या या रंग (यदि समर्थित हो)।
+
+इस उदाहरण में हम 15 कैरेक्टर्स का हाइलाइट रेडियस सेट करते हैं:
+
+`HighlightOptions` हाइलाइटेड सर्च हिट्स के लिए कंटेक्स्ट रेडियस और विज़ुअल सेटिंग्स निर्दिष्ट करता है।
+
+```java
+HighlightOptions highlightOptions = new HighlightOptions(15);
+```
+
+यह पाया गया टेक्स्ट को आसपास के कंटेक्स्ट के साथ रैप करता है—जैसे आपके कीवर्ड्स के चारों ओर एक मैग्नीफ़ाइंग ग्लास—जिससे यह देखना आसान हो जाता है कि मैच कहाँ हुआ।
+
+### चरण 3: दस्तावेज़ में सर्च निष्पादित करें
+
+**सर्च कैसे काम करता है?**
+`parser.search` का उपयोग करके आप कीवर्ड या फ़्रेज़, सर्च ऑप्शन, और फिर `SearchResult` ऑब्जेक्ट्स का इटेरेबल कलेक्शन प्राप्त करते हैं।
+
+`SearchOptions` केस‑सेंसिटिविटी जैसे सर्च पैरामीटर्स को कॉन्फ़िगर करता है। `SearchResult` प्रत्येक मैच का विवरण रखता है, जिसमें मैच्ड टेक्स्ट और उसकी लोकेशन शामिल है।
+
+```java
+Iterable results = parser.search("lorem", new SearchOptions(true, false, false, highlightOptions));
+```
+
+`SearchOptions` कंस्ट्रक्टर का विवरण:
+
+- `true`: केस‑इनसेंसिटिव सर्च सक्षम करें।
+- `false`: केवल पूरे शब्दों से मैच न करें।
+- `false`: रेगुलर एक्सप्रेशन पैटर्न सर्च न करें।
+- `highlightOptions`: हमारी हाइलाइट कॉन्फ़िगरेशन पास करें।
+
+यह सेटअप सभी `"lorem"` घटनाओं को केस‑इग्नोर करते हुए खोजता है, और हाइलाइटेड स्निपेट्स देता है।
+
+### चरण 4: सर्च सपोर्ट और परिणामों को हैंडल करें
+
+**सर्च सपोर्ट की जाँच करें**
+कुछ फॉर्मेट सर्च को सपोर्ट नहीं कर सकते — हमेशा पुष्टि करें:
+
+`parser.isSearchSupported()` एक बूलियन रिटर्न करता है जो बताता है कि लोड किया गया दस्तावेज़ फॉर्मेट टेक्स्ट सर्च की अनुमति देता है या नहीं।
+
+```java
+if (results == null) {
+ System.out.println("Search isn't supported in this document format.");
+ return;
+}
+```
+
+**प्रत्येक सर्च हिट को प्रोसेस करें**
+परिणामों पर लूप करके मिलते‑जुलते स्निपेट्स को हाइलाइट के साथ एक्सट्रैक्ट और डिस्प्ले करें:
+
+`SearchResult` ऑब्जेक्ट्स आपको मैच्ड फ़्रेज़ और उसके आसपास के कंटेक्स्ट तक पहुंच प्रदान करते हैं।
+
+```java
+for (SearchResult result : results) {
+ String snippet = String.format("%s%s%s",
+ result.getLeftHighlightItem().getText(),
+ result.getText(),
+ result.getRightHighlightItem().getText());
+ System.out.println(snippet);
+}
+```
+
+## सामान्य समस्याएँ और समाधान
+
+| समस्या | कारण | समाधान |
+|-------|--------|-----|
+| **कोई परिणाम नहीं मिला** | दस्तावेज़ फॉर्मेट सर्चेबल नहीं है | `parser.isSearchSupported()` `true` है या नहीं, सत्यापित करें। |
+| **हाइलाइट रेडियस बहुत छोटा लगता है** | डिफ़ॉल्ट रेडियस 10 कैरेक्टर है | `HighlightOptions` में रेडियस बढ़ाएँ (उदा., `new HighlightOptions(20)`)। |
+| **बड़े PDFs पर Out‑of‑Memory त्रुटि** | पूरी फ़ाइल मेमोरी में लोड हो रही है | स्ट्रीमिंग मोड के साथ `Parser` उपयोग करें या फ़ाइल को चंक्स में प्रोसेस करें; GroupDocs.Parser पहले से ही बड़े फ़ाइलों को कुशलता से स्ट्रीम करता है। |
+| **केस‑सेंसिटिविटी अपेक्षित रूप से काम नहीं कर रही** | `caseSensitive` फ़्लैग गलत सेट है | सुनिश्चित करें कि `SearchOptions(true, …)` केस‑इनसेंसिटिविटी के लिए सही बूलियन सेट कर रहा है। |
+
+## अक्सर पूछे जाने वाले प्रश्न
+
+**प्रश्न: क्या मैं एक साथ कई कीवर्ड सर्च कर सकता हूँ?**
+उत्तर: सीधे नहीं; प्रत्येक कीवर्ड पर इटरेट करें या एक रेगेक्स पैटर्न बनाएं जो सभी इच्छित शब्दों को मैच करे।
+
+**प्रश्न: क्या हाइलाइट रेडियस सभी दस्तावेज़ फॉर्मेट पर प्रभाव डालता है?**
+उत्तर: अधिकांश समर्थित फॉर्मेट में रेडियस समान रूप से काम करता है; कुछ इमेज‑आधारित फॉर्मेट इसे अनदेखा करते हैं क्योंकि उनके पास नेटिव टेक्स्ट लेयर नहीं होती।
+
+**प्रश्न: क्या मैं हाइलाइट रंग बदल सकता हूँ?**
+उत्तर: `HighlightOptions` कंटेक्स्ट रेडियस नियंत्रित करता है; विज़ुअल रंग उस व्यूअर पर निर्भर करता है जिसका आप PDF रेंडर करने के लिए उपयोग करते हैं, न कि पार्सर पर।
+
+**प्रश्न: क्या सर्च डिफ़ॉल्ट रूप से केस‑सेंसिटिव है?**
+उत्तर: नहीं। `SearchOptions` में `caseSensitive` को `false` सेट करने से सर्च केस‑इनसेंसिटिव हो जाता है।
+
+**प्रश्न: क्या यह स्कैन किए गए इमेजेज़ पर काम करता है या केवल टेक्स्ट‑आधारित फ़ाइलों पर?**
+उत्तर: सर्च टेक्स्ट‑आधारित दस्तावेज़ों पर काम करता है। स्कैन किए गए इमेजेज़ के लिए OCR क्षमता चाहिए, जो GroupDocs OCR एक अलग मॉड्यूल के रूप में प्रदान करता है।

+# GroupDocs.Parser के साथ EPUB टेक्स्ट सर्च के लिए रेगेक्स का उपयोग कैसे करें
+
+इस व्यावहारिक गाइड में आप सीखेंगे **रेगेक्स का उपयोग कैसे करें** ताकि GroupDocs.Parser for Java का उपयोग करके EPUB फ़ाइलों के भीतर टेक्स्ट खोजा जा सके। चाहे आप एक डिजिटल‑लाइब्रेरी इंडेक्सर बना रहे हों या हजारों ई‑बुक्स में विशिष्ट वाक्यांशों को खोजने की आवश्यकता हो, रेगुलर‑एक्सप्रेशन सर्च में महारत हासिल करने से आपका समय बचेगा और सटीकता बढ़ेगी। हम सेटअप, मुख्य क्लासेज़, और व्यावहारिक पैटर्न को कवर करेंगे, साथ ही **epub कैसे खोजें** फ़ाइलों को प्रभावी ढंग से खोजने पर भी चर्चा करेंगे।
+
+## त्वरित उत्तर
+- **Java में EPUB को पार्स करने वाली लाइब्रेरी कौन सी है?** GroupDocs.Parser for Java.
+- **क्या मैं EPUB सर्च के लिए रेगेक्स का उपयोग कर सकता हूँ?** हाँ – API Java Pattern ऑब्जेक्ट्स को स्वीकार करता है।
+- **केस‑सेंसिटिव सर्च कैसे करें?** `SearchOptions.setIgnoreCase(false)` सेट करें।
+- **क्या मुझे लाइसेंस चाहिए?** परीक्षण के लिए एक फ्री ट्रायल काम करता है; पूर्ण लाइसेंस सीमाओं को हटा देता है।
+- **कौन सा Java संस्करण आवश्यक है?** JDK 8 या उससे ऊपर।
+
+## GroupDocs.Parser क्या है?
+GroupDocs.Parser एक Java लाइब्रेरी है जो EPUB सहित 50 से अधिक दस्तावेज़ फ़ॉर्मैट्स से टेक्स्ट, इमेज और मेटाडेटा निकालती है। यह एक हाई‑लेवल `Parser` क्लास प्रदान करती है जो फ़ाइल हैंडलिंग को एब्स्ट्रैक्ट करती है, जिससे आप लो‑लेवल पार्सिंग के बजाय सर्च लॉजिक पर ध्यान केंद्रित कर सकते हैं। लाइब्रेरी कंटेंट को प्रभावी ढंग से स्ट्रीम करती है, मेमोरी‑सीमित वातावरण का समर्थन करती है, और बिल्ट‑इन सर्च क्षमताएँ प्रदान करती है जो सीधे पार्स किए गए टेक्स्ट पर काम करती हैं।
+
+## EPUB के लिए GroupDocs.Parser के साथ रेगेक्स क्यों उपयोग करें?
+- **विस्तृत फ़ॉर्मैट समर्थन:** 50+ इनपुट फ़ॉर्मैट्स को संभालता है, EPUB सहित, बिना बाहरी कन्वर्टर्स के।
+- **मेमोरी‑कुशल प्रोसेसिंग:** कंटेंट को स्ट्रीम करता है, जिससे कई‑सौ‑पृष्ठों वाले EPUB को पूरी फ़ाइल को RAM में लोड किए बिना खोजा जा सकता है।
+- **सटीक पैटर्न मिलान:** रेगेक्स आपको पूरे शब्द, वाक्यांश, या जटिल पैटर्न (जैसे तिथियां, ISBN) को एक ही कॉल में खोजने देता है।
+
+## पूर्वापेक्षाएँ
+- **Java Development Kit (JDK) 8+** स्थापित और आपके IDE या बिल्ड टूल में कॉन्फ़िगर किया हुआ।
+- **GroupDocs.Parser for Java** लाइब्रेरी (Maven या सीधे डाउनलोड के माध्यम से उपलब्ध)।
+- Java सिंटैक्स और रेगुलर‑एक्सप्रेशन अवधारणाओं की बुनियादी परिचितता।
+
+## EPUB फ़ाइलों में टेक्स्ट सर्च के लिए रेगेक्स कैसे उपयोग करें?
+`new Parser("book.epub")` के साथ अपना EPUB लोड करें और एक कम्पाइल्ड `Pattern` का उपयोग करके `search` को कॉल करें। यह दो‑स्टेप दृष्टिकोण फ़ाइल लोडिंग को पैटर्न निष्पादन से अलग करता है, जिससे बड़े संग्रहों पर भी इष्टतम प्रदर्शन सुनिश्चित होता है।
+
+### चरण 1: Parser को इनिशियलाइज़ करें
+`Parser` क्लास EPUB फ़ाइल को लोड करने और हैंडल करने के लिए एंट्री पॉइंट है।
+```java
+// ```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/parser/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5
+
+
+```
+```
+
+### चरण 2: रेगेक्स पैटर्न बनाएं
+Java की `Pattern` क्लास रेगुलर एक्सप्रेशन को कम्पाइल करती है। उदाहरण के लिए, किसी भी शब्द को खोजने के लिए जो whitespace कैरेक्टर के बाद “list” से शुरू होता है, `\\slist\\w*` का उपयोग करें।
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+// Initialize Parser object with an EPUB file path
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.epub")) {
+ // Your code here
+}
+```
+```
+
+### चरण 3: सर्च विकल्प कॉन्फ़िगर करें
+`SearchOptions` सर्च के संचालन को कॉन्फ़िगर करता है, जैसे केस सेंसिटिविटी और फज़ी मैचिंग।
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+String epubFilePath = "YOUR_DOCUMENT_DIRECTORY/sample.epub";
+
+try (Parser parser = new Parser(epubFilePath)) {
+ // Further processing steps go here
+}
+```
+```
+
+### चरण 4: सर्च निष्पादित करें
+`SearchResult` एक सिंगल मैच को दर्शाता है, जिसमें टेक्स्ट, पेज नंबर, और कैरेक्टर ऑफसेट शामिल होते हैं।
+```java
+// ```java
+String regexPattern = \\slist; // Matches any word preceded by whitespace and 'list'
+```
+```
+
+### चरण 5: परिणाम प्रोसेस करें
+`SearchResult` कलेक्शन पर इटररेट करें ताकि मैच को लॉग किया जा सके, डेटाबेस में स्टोर किया जा सके, या इंडेक्सिंग या अलर्टिंग जैसे डाउनस्ट्रीम वर्कफ़्लो को ट्रिगर किया जा सके।
+```java
+// ```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options for search
+SearchOptions options = new SearchOptions(true /* case match */, false /* whole word */, true /* fuzzy */);
+```
+```
+
+## Java में केस‑सेंसिटिव सर्च कैसे करें?
+`SearchOptions.setIgnoreCase(false)` सेट करें ताकि सटीक केस मिलान लागू हो। यह पहचानकर्ताओं, कोड स्निपेट्स, या ब्रांड नामों की खोज में आवश्यक है जिन्हें अपनी मूल केसिंग बनाए रखना होता है।
+
+## सामान्य उपयोग केस
+1. **डिजिटल लाइब्रेरी इंडेक्सिंग:** हजारों EPUB शीर्षकों के लिए स्वचालित रूप से सर्चेबल इंडेक्स बनाएं।
+2. **कंटेंट क्यूरेशन:** शोध के लिए कई पुस्तकों में थीमैटिक सेक्शन (जैसे “Chapter 5”) खोजें।
+3. **डेटा माइनिंग:** कस्टम रेगेक्स पैटर्न का उपयोग करके ISBN, तिथियां, या लेखक नाम जैसी संरचित एंटिटीज़ निकालें।
+4. **ई‑लर्निंग इंटीग्रेशन:** कोर्स प्लेटफ़ॉर्म को कोर्स सामग्री PDFs और EPUBs के लिए त्वरित फुल‑टेक्स्ट सर्च क्षमताओं से सुदृढ़ बनाएं।
+
+## प्रदर्शन टिप्स
+- **रेगेक्स पैटर्न को ऑप्टिमाइज़ करें:** CPU उपयोग कम रखने के लिए बैक‑ट्रैकिंग‑भारी कंस्ट्रक्ट्स के बजाय सरल कैरेक्टर क्लासेज़ को प्राथमिकता दें।
+- **बड़े EPUB को चंक करें:** यदि फ़ाइल 200 MB से अधिक है तो मेमोरी स्पाइक से बचने के लिए अध्यायों को व्यक्तिगत रूप से प्रोसेस करें।
+- **बार-बार क्वेरीज़ को कैश करें:** लोकप्रिय पैटर्न (जैसे सामान्य कीवर्ड) के परिणाम को हल्के इन‑मेमोरी मैप में स्टोर करें।
+
+## अक्सर पूछे जाने वाले प्रश्न
+
+**Q: `search` और `extractText` में क्या अंतर है?**
+A: `search` रेगेक्स पैटर्न लागू करता है और केवल मिलते हुए फ्रैगमेंट्स लौटाता है, जबकि `extractText` पूरे दस्तावेज़ की सामग्री को बिना फ़िल्टर किए लौटाता है।
+
+**Q: क्या मैं एक कॉल में कई EPUB फ़ाइलों को खोज सकता हूँ?**
+A: कोई एकल API कॉल बैच प्रोसेस नहीं करता, लेकिन आप फ़ाइल सूची पर लूप कर सकते हैं, प्रत्येक फ़ाइल के लिए वही `Pattern` और `SearchOptions` पुन: उपयोग कर सकते हैं।
+
+**Q: फज़ी सर्च कैसे काम करता है?**
+A: `SearchOptions` में फज़ी मोड सक्षम करें ताकि दो एडिट्स तक की लेवेनस्टीन दूरी की अनुमति मिले, जिससे स्पेलिंग त्रुटियों और छोटे अंतर को कैप्चर किया जा सके।
+
+**Q: दस्तावेज़ आकार पर कोई सीमा है?**
+A: GroupDocs.Parser 500 MB तक के EPUB को संभाल सकता है; बड़े फ़ाइलों को मैन्युअल रूप से विभाजित या स्ट्रीम किया जाना चाहिए।
+
+**Q: विकास के लिए मुझे लाइसेंस चाहिए?**
+A: फ्री ट्रायल पूर्ण API एक्सेस के साथ उपयोग वॉटरमार्क देता है; एक स्थायी लाइसेंस प्रतिबंधों को हटाता है और व्यावसायिक अधिकार प्रदान करता है।

+**आरंभिककरण**
+लाइब्रेरी जोड़ने के बाद, अपने Java एप्लिकेशन को GroupDocs.Parser उपयोग करने के लिए इनिशियलाइज़ करें:
+
+```java
+import com.groupdocs.parser.Parser;
+
+public class SetupExample {
+ public static void main(String[] args) {
+ String filePath = "path/to/your/document.html";

+}
+```
+
+## GroupDocs.Parser for Java का उपयोग करके HTML कैसे खोजें?
+`Parser` क्लास के साथ अपना HTML फ़ाइल लोड करें और केवल दो पंक्तियों के कोड में regex खोज निष्पादित करें। `Parser` क्लास वह एंट्री पॉइंट है जो समर्थित दस्तावेज़ प्रकारों को पढ़ता और पार्स करता है, टेक्स्ट एक्सट्रैक्शन और सर्च के लिए मेथड्स प्रदान करता है। `SearchOptions` को कॉन्फ़िगर करके, आप पार्सर को बताते हैं कि आपका पैटर्न एक नियमित अभिव्यक्ति है, वैकल्पिक रूप से केस‑सेंसिटिव या पूरे शब्द मिलान को सक्षम कर सकते हैं।
+
+### चरण‑दर‑चरण कार्यान्वयन
+
+### चरण 1: अपना नियमित अभिव्यक्ति पैटर्न परिभाषित करें
+पहले, वह regex पैटर्न बनाएं जो आपको चाहिए टेक्स्ट से मेल खाता हो। इस उदाहरण में हम उन शब्दों की खोज करते हैं जो **“Sub”** से शुरू होते हैं और उसके बाद एक अंक आता है (जैसे `Sub1`, `Sub9`).
+
+```java
+String regexPattern = "Sub[0-9]";
+```
+
+### चरण 2: सर्च विकल्प सेट करें
+`SearchOptions` एक कॉन्फ़िगरेशन ऑब्जेक्ट है जो सर्च व्यवहार को निर्दिष्ट करता है जैसे regex मोड और केस सेंसिटिविटी।
+`SearchOptions` ऑब्जेक्ट को regex मोड सक्रिय करने, केस सेंसिटिविटी सेट करने, और केवल पूरे शब्द मिलान करना है या नहीं, यह तय करने के लिए कॉन्फ़िगर करें। `SearchOptions` एक कॉन्फ़िगरेशन होल्डर है जो पार्सर को बताता है कि सर्च कैसे किया जाए।
+
+```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options: case-sensitive, whole word, use regex
+SearchOptions options = new SearchOptions(true, false, true);
+```
+
+### चरण 3: खोज निष्पादित करें
+`Parser` इंस्टेंस पर `search` मेथड को कॉल करें, HTML फ़ाइल पाथ, पैटर्न, और विकल्प पास करते हुए। यह मेथड `SearchResult` ऑब्जेक्ट्स का संग्रह लौटाता है, प्रत्येक में मिलान किया गया टेक्स्ट और दस्तावेज़ में उसकी स्थिति होती है।
+
+```java
+import com.groupdocs.parser.data.SearchResult;
+
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.html")) {
+ Iterable results = parser.search(regexPattern, options);
+
+ for (SearchResult result : results) {
+ System.out.println(String.format("At %d: %s", result.getPosition(), result.getText()));
+ }
+} catch (Exception e) {
+ e.printStackTrace();
+}
+```
+
+**मुख्य कॉन्फ़िगरेशन विकल्प**
+- **Case Sensitivity** – सटीक‑केस मिलान के लिए `true` सेट करें।
+- **Whole Word Search** – `false` आंशिक मिलान शामिल करता है।
+- **Use Regular Expressions** – regex प्रोसेसिंग को सक्षम करने के लिए `true` होना चाहिए।
+
+## सामान्य समस्याएँ और समाधान
+- **Incorrect file path** – सत्यापित करें कि HTML फ़ाइल आपके एप्लिकेशन की कार्यशील डायरेक्टरी से पहुँच योग्य है।
+- **Invalid regex syntax** – कोड में एम्बेड करने से पहले अपने पैटर्न को ऑनलाइन regex टेस्टर से परीक्षण करें।
+- **Memory leaks** – हमेशा `Parser` इंस्टेंस को बंद करें या try‑with‑resources का उपयोग करें ताकि स्ट्रीम्स रिलीज़ हो सकें।
+
+## व्यावहारिक अनुप्रयोग
+HTML में regex‑आधारित खोजों का उपयोग कई वास्तविक‑दुनिया परिदृश्यों के द्वार खोलता है:
+
+1. **Data Extraction** – बल्क HTML रिपोर्टों से इनवॉइस नंबर, IDs, या टाइमस्टैम्प निकालें।
+2. **Content Filtering** – प्रतिबंधित कीवर्ड वाले सेक्शन को स्वचालित रूप से हटाएँ या फ़्लैग करें।
+3. **Log Analysis** – त्रुटि पैटर्न या प्रदर्शन मीट्रिक के लिए HTML‑फ़ॉर्मेटेड लॉग स्कैन करें।
+4. **ETL Pipelines** – वेब‑स्क्रैप्ड कंटेंट को सामान्यीकृत करने वाले डेटा‑इन्गेस्ट्शन वर्कफ़्लो में पार्सर को एकीकृत करें।
+
+## प्रदर्शन संबंधी विचार
+बड़े HTML कॉर्पोरा को संभालते समय इन टिप्स को याद रखें:
+
+- **Optimize regex patterns** – अत्यधिक बैकट्रैकिंग से बचें; संभव हो तो एटॉमिक ग्रुप्स या पॉज़ेसिव क्वांटिफ़ायर्स का उपयोग करें।
+- **Streamline memory usage** – पार्सिंग को try‑with‑resources ब्लॉक में लपेटें ताकि JVM बफ़र्स को शीघ्र पुनः प्राप्त कर सके।
+- **Parallel processing** – कई दस्तावेज़ों को एक साथ खोजने के लिए Java के `ForkJoinPool` का उपयोग करें, जिससे मल्टी‑कोर सर्वरों पर रैखिक स्केलिंग प्राप्त हो।
+
+## अक्सर पूछे जाने वाले प्रश्न
+
+**Q: नियमित अभिव्यक्ति क्या है?**
+A: नियमित अभिव्यक्ति (regex) एक संक्षिप्त, पैटर्न‑आधारित भाषा है जो स्ट्रिंग्स के भीतर कैरेक्टर अनुक्रमों को मिलाने के लिए उपयोग की जाती है, और वैधता, खोज, तथा टेक्स्ट मैनिपुलेशन में व्यापक रूप से प्रयुक्त होती है।
+
+**Q: क्या GroupDocs.Parser गैर‑HTML फ़ाइलों को संभाल सकता है?**
+A: हाँ, यह 70 से अधिक फ़ॉर्मैट्स को सपोर्ट करता है—जिसमें PDF, DOCX, XLSX, और PPTX शामिल हैं—इसलिए समान सर्च लॉजिक विभिन्न दस्तावेज़ प्रकारों में काम करता है।
+
+**Q: पार्सिंग त्रुटियों को कैसे संभालें?**
+A: पार्सिंग कोड को try‑catch ब्लॉक में रखें, `ParserException` को पकड़ें ताकि समस्या को लॉग किया जा सके और संसाधनों को बंद किया जा सके।
+
+**Q: मेरा regex कोई परिणाम नहीं देता—क्या समस्या है?**
+A: पैटर्न में एस्केप्ड कैरेक्टर्स की दोबारा जाँच करें, केस‑सेंसिटिविटी सेटिंग्स सत्यापित करें, और पुष्टि करें कि लक्ष्य टेक्स्ट वास्तव में HTML स्रोत में मौजूद है।
+
+**Q: HTML फ़ाइलों का आकार सीमा है क्या?**
+A: GroupDocs.Parser 2 GB तक की फ़ाइलें प्रोसेस कर सकता है; अत्यधिक बड़े HTML फ़ाइलों के लिए, उन्हें विभाजित करने या सेक्शन को स्ट्रीम करने पर विचार करें ताकि मेमोरी प्रतिबंधों के भीतर रहें।
+
+## निष्कर्ष
+इस गाइड का पालन करके आप अब **how to search html** दस्तावेज़ों को GroupDocs.Parser for Java में निर्मित शक्तिशाली regex इंजन का उपयोग करके खोजना जानते हैं। आप तेज़ी से पैटर्न खोज सकते हैं, सार्थक डेटा निकाल सकते हैं, और समाधान को बड़े Java एप्लिकेशन या डेटा पाइपलाइन में एकीकृत कर सकते हैं।
+
+**अगले कदम:** अधिक जटिल पैटर्न के साथ प्रयोग करें, कई `SearchOptions` को संयोजित करें, या ऑन‑डिमांड टेक्स्ट एक्सट्रैक्शन के लिए पार्सर को Spring Boot माइक्रोसर्विस में एम्बेड करें।

+# Java PDF 處理：搜尋與突出顯示（使用 GroupDocs）
+
+Ever find yourself drowning in a sea of documents—PDFs, Word files, or other formats—and wish you could effortlessly find specific words or phrases? **Java PDF processing** makes that possible. In this guide you’ll learn how to search text inside PDFs and generate highlighted snippets using **GroupDocs.Parser for Java**. Whether you’re building a document‑analysis tool or automating content review, the steps below give you a clear, production‑ready solution.
+
+## 快速解答
+- **哪個函式庫在 Java 中處理 PDF 文字搜尋？** GroupDocs.Parser for Java.
+- **開發時需要授權嗎？** 臨時授權可用於測試；正式環境需購買完整授權。
+- **我可以一次突出顯示多個出現嗎？** 可以——設定 highlight radius 後遍歷結果即可。
+- **搜尋是否區分大小寫？** 預設為不區分大小寫；可透過 `SearchOptions` 切換。
+- **支援哪些格式？** 超過 50 種輸入與輸出格式，包含 PDF、DOCX、XLSX、PPTX、HTML 與影像。
+
+## 什麼是 Java PDF 處理？
+`Java PDF processing` 是指使用 Java 函式庫對 PDF 檔案執行程式化操作——例如抽取、搜尋與突出顯示文字。透過 GroupDocs.Parser，您可以搜尋任何支援的文件、取得前後文，並套用視覺上的突出顯示，全部不需在檢視器中開啟檔案。此功能讓您能建立快速、可搜尋的檔案庫與自動化審閱流程，且可支援每份文件上千頁。
+
+## 為什麼使用 GroupDocs.Parser 進行 Java PDF 處理？
+GroupDocs.Parser 支援 **50+ 檔案格式**，且能在不將整個檔案載入記憶體的情況下處理 **數百頁的 PDF**，相較於傳統做法可降低記憶體使用量高達 **70 %**。其搜尋引擎回傳精確的偏移量，讓您能自行建立 UI 突出顯示或將結果匯出至其他系統。此函式庫持續維護，相容 Java 8+，並提供 Maven 與 Gradle 套件，方便整合。
+
+## 前置條件
+
+在開始之前，請先確保以下項目已備妥：
+
+- **Java 開發環境**：已安裝 JDK 8+。
+- **Maven 或 Gradle**：用於相依管理與專案設定。
+- **GroupDocs.Parser for Java 函式庫**：下載或透過相依加入。
+- **範例文件**：測試用的 PDF 或文字檔。
+- **基本的 Java 知識**：熟悉類別、方法與檔案處理。
+
+如果尚未取得函式庫，可從 [GroupDocs Downloads](https://releases.groupdocs.com/parser/java/) 下載最新版本，或透過 Maven 加入：
+
+```xml
+
+ com.groupdocs
+ groupdocs-parser
+ 21.12
+
+```
+
+## 匯入套件
+
+首先，匯入 GroupDocs.Parser 所需的核心類別：
+
+`Parser` 為載入與操作文件的主要類別。`HighlightOptions` 用於設定匹配文字的突出顯示方式。`SearchOptions` 定義搜尋行為（例如是否區分大小寫）。`SearchResult` 代表文件中找到的單一匹配項目。
+
+```java
+import com.groupdocs.parser.Parser;
+import com.groupdocs.parser.search.HighlightOptions;
+import com.groupdocs.parser.search.SearchOptions;
+import com.groupdocs.parser.search.SearchResult;
+```
+
+以上匯入涵蓋了文件解析、設定突出顯示選項以及執行搜尋的核心功能。
+
+## 搜尋與突出顯示工作流程如何運作？
+
+載入 PDF、設定 `HighlightOptions` 物件、呼叫 `parser.search`，然後遍歷 `SearchResult` 集合以產生突出顯示的片段。整個流程分為兩步：第一步，解析器讀取文件結構；第二步，搜尋引擎在文字串流中套用您定義的選項。此方式即使在大型檔案上也能保持高效能。
+
+## 步驟說明：搜尋文字並突出顯示
+
+以下將流程拆解為可管理的明確步驟。每一步皆附有說明，協助您了解背後的原理與操作方式。
+
+### 步驟 1：使用文件初始化 Parser
+
+**這裡發生了什麼？**
+建立與文件檔案關聯的 `Parser` 實例，讓您能存取並分析其內容。
+
+`Parser` 會載入文件，並提供文字抽取與搜尋的方法。
+
+```java
+try (Parser parser = new Parser("path/to/your/document.pdf")) {
+ // your code here
+}
+```
+
+**實際上：**
+`try-with-resources` 陳述式確保檔案在處理完畢後正確關閉，避免資源泄漏。請將 `"path/to/your/document.pdf"` 替換為實際的檔案路徑或 URL。
+
+### 步驟 2：設定突出顯示選項
+
+**為什麼要定義突出顯示選項？**
+您可能想控制搜尋結果的外觀或行為，例如顯示匹配文字前後的字元數或顏色（若支援）。
+
+本例中，我們將突出顯示半徑設為 15 個字元：
+
+`HighlightOptions` 指定了上下文半徑與視覺設定，用於突出顯示搜尋命中的文字。
+
+```java
+HighlightOptions highlightOptions = new HighlightOptions(15);
+```
+
+這會將找到的文字以周圍上下文包裹起來——就像放大鏡聚焦關鍵字，讓您更容易辨識匹配位置。
+
+### 步驟 3：在文件中執行搜尋
+
+**搜尋是如何運作的？**
+使用 `parser.search`，傳入關鍵字或片語、搜尋選項，便可取得 `SearchResult` 物件的可遍歷集合。
+
+`SearchOptions` 設定搜尋參數（例如是否區分大小寫）。`SearchResult` 包含每筆匹配的文字與位置資訊。
+
+```java
+Iterable results = parser.search("lorem", new SearchOptions(true, false, false, highlightOptions));
+```
+
+`SearchOptions` 建構子說明：
+
+- `true`：啟用不區分大小寫的搜尋。
+- `false`：不僅限全字匹配。
+- `false`：不使用正規表達式。
+- `highlightOptions`：傳入先前設定的突出顯示配置。
+
+此設定會搜尋所有 `"lorem"` 出現，忽略大小寫，並產生帶有突出顯示的片段。
+
+### 步驟 4：處理搜尋支援與結果
+
+**檢查是否支援搜尋**
+某些格式可能不支援搜尋——務必先確認：
+
+`parser.isSearchSupported()` 會回傳布林值，表示已載入的文件格式是否允許文字搜尋。
+
+```java
+if (results == null) {
+ System.out.println("Search isn't supported in this document format.");
+ return;
+}
+```
+
+**處理每筆搜尋結果**
+遍歷結果以抽取並顯示帶有突出顯示的片段：
+
+`SearchResult` 物件提供匹配片語及其前後文的存取方式。
+
+```java
+for (SearchResult result : results) {
+ String snippet = String.format("%s%s%s",
+ result.getLeftHighlightItem().getText(),
+ result.getText(),
+ result.getRightHighlightItem().getText());
+ System.out.println(snippet);
+}
+```
+
+## 常見問題與解決方案
+
+| 問題 | 原因 | 解決方案 |
+|------|------|----------|
+| **未返回結果** | 文件格式不支援搜尋 | 確認 `parser.isSearchSupported()` 回傳 `true`。 |
+| **突出顯示半徑似乎太小** | 預設半徑為 10 個字元 | 在 `HighlightOptions` 中增加半徑（例如 `new HighlightOptions(20)`）。 |
+| **大型 PDF 發生記憶體不足錯誤** | 整個檔案被載入記憶體 | 使用 `Parser` 的串流模式或分塊處理檔案；GroupDocs.Parser 已有效率地串流大型檔案。 |
+| **大小寫敏感性未如預期運作** | `caseSensitive` 旗標設定錯誤 | 確保在 `SearchOptions(true, …)` 中正確設定大小寫不敏感的布林值。 |
+
+## 常見問答
+
+**Q: 我可以一次搜尋多個關鍵字嗎？**
+A: 無法直接一次搜尋多個關鍵字；您可以對每個關鍵字分別迭代，或構造一個匹配所有目標詞的正規表達式。
+
+**Q: 突出顯示半徑會影響所有文件格式嗎？**
+A: 大多數支援的格式半徑皆以相同方式運作；某些基於影像的格式會忽略半徑，因為它們缺乏原生文字層。
+
+**Q: 我可以更改突出顯示顏色嗎？**
+A: `HighlightOptions` 只控制上下文半徑；實際的顏色取決於您用來渲染 PDF 的檢視器，而非解析器本身。
+
+**Q: 預設搜尋是否區分大小寫？**
+A: 不會。將 `caseSensitive` 設為 `false`（在 `SearchOptions` 中）即可使搜尋不區分大小寫。
+
+**Q: 這適用於掃描圖像還是僅文字檔案？**
+A: 搜尋僅適用於文字型文件。若要在掃描圖像上搜尋，需使用 OCR 功能，GroupDocs OCR 為獨立模組。

+GroupDocs.Parser 是一個 Java 程式庫，可從超過 50 種文件格式（包括 EPUB）中擷取文字、影像與中繼資料。它提供高階的 `Parser` 類別，抽象化檔案處理，讓您專注於搜尋邏輯而非低階解析。此程式庫能有效串流內容，支援記憶體受限的環境，並提供內建的搜尋功能，直接在已解析的文字上運作。
+
+## 為何在 EPUB 中搭配 GroupDocs.Parser 使用正則表達式？
+- **廣泛的格式支援：** 處理 50+ 輸入格式，包含 EPUB，無需外部轉換器。
+- **記憶體效能處理：** 串流內容，使得數百頁的 EPUB 可在不將整個檔案載入記憶體的情況下搜尋。
+- **精確的模式匹配：** 正則表達式讓您在一次呼叫中定位完整單字、片語或複雜模式（例如日期、ISBN）。
+
+## 前置條件
+- **Java Development Kit (JDK) 8+** 已安裝並在您的 IDE 或建置工具中設定。
+- **GroupDocs.Parser for Java** 程式庫（可透過 Maven 或直接下載取得）。
+- 具備 Java 語法與正則表達式概念的基本熟悉度。
+
+## 如何使用正則表達式在 EPUB 檔案中搜尋文字？
+使用 `new Parser("book.epub")` 載入您的 EPUB，並使用已編譯的 `Pattern` 呼叫 `search`。此兩步驟方法將檔案載入與模式執行分離，即使在大型集合上也能確保最佳效能。
+
+### 步驟 1：初始化 Parser
+`Parser` 類別是載入與處理 EPUB 檔案的入口點。
+```java
+// ```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/parser/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5
+
+
+```
+```
+
+### 步驟 2：建立正則表達式模式
+Java 的 `Pattern` 類別會編譯正則表達式。例如，要找出在空白字元後以 “list” 開頭的任何單字，可使用 `\\slist\\w*`。
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+// Initialize Parser object with an EPUB file path
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.epub")) {
+ // Your code here
+}
+```
+```
+
+### 步驟 3：設定搜尋選項
+`SearchOptions` 設定搜尋的運作方式，例如大小寫敏感度與模糊匹配。
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+String epubFilePath = "YOUR_DOCUMENT_DIRECTORY/sample.epub";
+
+try (Parser parser = new Parser(epubFilePath)) {
+ // Further processing steps go here
+}
+```
+```
+
+### 步驟 4：執行搜尋
+`SearchResult` 代表單一匹配結果，包含文字、頁碼與字元偏移量。
+```java
+// ```java
+String regexPattern = \\slist; // Matches any word preceded by whitespace and 'list'
+```
+```
+
+### 步驟 5：處理結果
+遍歷 `SearchResult` 集合以記錄匹配項目、將其儲存至資料庫，或觸發後續工作流程，例如索引或警示。
+```java
+// ```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options for search
+SearchOptions options = new SearchOptions(true /* case match */, false /* whole word */, true /* fuzzy */);
+```
+```
+
+## 如何在 Java 中執行區分大小寫的搜尋？
+設定 `SearchOptions.setIgnoreCase(false)` 以強制精確的大小寫匹配。當搜尋必須保留原始大小寫的識別碼、程式碼片段或品牌名稱時，這點尤為重要。
+
+## 常見使用情境
+1. **數位圖書館索引：** 自動為數千本 EPUB 書名產生可搜尋的索引。
+2. **內容策展：** 在多本書中定位主題段落（例如 “Chapter 5”）以供研究。
+3. **資料探勘：** 使用客製化的正則表達式模式擷取結構化實體，如 ISBN、日期或作者姓名。
+4. **電子學習整合：** 為課程平台增強即時全文搜尋功能，支援課程資料 PDF 與 EPUB。
+
+## 效能建議
+- **優化正則表達式模式：** 偏好使用簡單的字元類別，避免大量回溯的結構，以降低 CPU 使用率。
+- **分段處理大型 EPUB：** 若檔案超過 200 MB，請分章處理，以避免記憶體突增。
+- **快取常用查詢：** 將常見模式（例如常見關鍵字）的結果儲存在輕量級的記憶體映射中。
+
+## 常見問答
+**Q: `search` 與 `extractText` 有何差異？**
+A: `search` 套用正則表達式模式並僅回傳匹配的片段，而 `extractText` 會回傳整個文件內容，不做過濾。
+
+**Q: 我能在一次呼叫中搜尋多個 EPUB 檔案嗎？**
+A: 單一 API 呼叫無法批次處理，但您可以遍歷檔案清單，對每個檔案重複使用相同的 `Pattern` 與 `SearchOptions`。
+
+**Q: 模糊搜尋如何運作？**
+A: 在 `SearchOptions` 中啟用模糊模式，可允許最多兩個編輯的 Levenshtein 距離，從而捕捉拼寫錯誤與輕微變化。
+
+**Q: 文件大小有上限嗎？**
+A: GroupDocs.Parser 可處理最高 500 MB 的 EPUB；較大的檔案應自行拆分或手動串流。
+
+**Q: 開發時需要授權嗎？**
+A: 免費試用提供完整 API 存取且帶有使用水印；正式授權則移除限制並授予商業使用權。

+- **效能如何？** GroupDocs.Parser 可在一般伺服器上於 2 秒內處理 500 頁的 HTML 檔案。
+
+## 正則表達式「如何搜尋 HTML」是什麼？
+**「How to search html」** 指的是使用正則表達式在 HTML 標記中定位文字模式。此技術讓您在不解析整個 DOM 樹的情況下，精確找出單詞、數字或自訂標籤。直接對原始 HTML 原始碼套用 regex，開發者即可快速抽取特定資料、驗證內容或過濾區段，是完整 DOM 解析的輕量替代方案。
+
+## 為何在正則搜尋時使用 GroupDocs.Parser for Java？
+GroupDocs.Parser 支援 **70+** 種輸入與輸出格式——包括 HTML、DOCX、XLSX 與 PDF——同時在不將整個檔案載入記憶體的情況下處理數百頁的文件。其原生的 `SearchOptions` 類別讓您啟用正則表達式、控制大小寫敏感度，並限制結果數量，提供快速且記憶體效率高的掃描。
+
+## 前置條件
+在開始之前，請確保您已具備以下項目：
+
+1. **GroupDocs.Parser for Java**（最新版本，例如 25.5 或更新）。
+2. 已安裝且在 IDE 中設定好的 **Java Development Kit** 8 或更新版本。
+3. 具備 **Java 正則表達式語法** 的基本認識（例如 `\d+`、`\bSub\w*`）。
+
+## 設定 GroupDocs.Parser for Java
+首先，將 Maven 依賴加入您的 `pom.xml`：
+
+```xml
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5
+
+```
+
+若直接下載，請前往 [GroupDocs.Parser for Java releases](https://releases.groupdocs.com/parser/java/) 取得最新版本。
+
+**授權取得**
+- **免費試用** – 探索核心功能，無需付費。
+- **臨時授權** – 從 [GroupDocs 的網站](https://purchase.groupdocs.com/temporary-license/) 申請延長測試金鑰。
+- **購買** – 取得完整授權，以供無限制的正式環境使用。
+
+**初始化**
+加入函式庫後，初始化您的 Java 應用程式以使用 GroupDocs.Parser：
+
+```java
+import com.groupdocs.parser.Parser;
+
+public class SetupExample {
+ public static void main(String[] args) {
+ String filePath = "path/to/your/document.html";
+ try (Parser parser = new Parser(filePath)) {
+ // Initialization complete, ready to parse and search!
+ } catch (Exception e) {
+ e.printStackTrace();
+ }
+ }
+}
+```
+
+## 如何使用 GroupDocs.Parser for Java 搜尋 HTML？
+使用 `Parser` 類別載入 HTML 檔案，僅用兩行程式碼即可執行正則搜尋。`Parser` 類別是讀取與解析支援文件類型的入口，提供文字抽取與搜尋的方法。透過設定 `SearchOptions`，您可告訴 parser 將模式視為正則表達式，並可選擇啟用大小寫敏感或全字匹配。
+
+### 步驟實作
+
+### 步驟 1：定義正則表達式模式
+首先，編寫符合需求的 regex 模式。在此範例中，我們搜尋以 **「Sub」** 開頭且後接數字的單詞（例如 `Sub1`、`Sub9`）。
+
+```java
+String regexPattern = "Sub[0-9]";
+```
+
+### 步驟 2：設定搜尋選項
+`SearchOptions` 是一個設定物件，用於指定搜尋行為，例如正則模式與大小寫敏感度。
+設定 `SearchOptions` 物件以啟用正則模式、設定大小寫敏感性，並決定是否僅匹配完整單詞。`SearchOptions` 作為配置持有者，告訴 parser 如何執行搜尋。
+
+```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options: case-sensitive, whole word, use regex
+SearchOptions options = new SearchOptions(true, false, true);
+```
+
+### 步驟 3：執行搜尋
+在 `Parser` 實例上呼叫 `search` 方法，傳入 HTML 檔案路徑、模式與選項。該方法回傳 `SearchResult` 物件集合，每個物件包含匹配的文字及其在文件中的位置。
+
+```java
+import com.groupdocs.parser.data.SearchResult;
+
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.html")) {
+ Iterable results = parser.search(regexPattern, options);
+
+ for (SearchResult result : results) {
+ System.out.println(String.format("At %d: %s", result.getPosition(), result.getText()));
+ }
+} catch (Exception e) {
+ e.printStackTrace();
+}
+```
+
+**關鍵設定選項**
+- **大小寫敏感** – 設為 `true` 以進行完全相同大小寫的匹配。
+- **全字搜尋** – 設為 `false` 時會包含部分匹配。
+- **使用正則表達式** – 必須設為 `true` 才能啟用 regex 處理。
+
+## 常見問題與解決方案
+- **檔案路徑不正確** – 確認 HTML 檔案在應用程式工作目錄下可被存取。
+- **正則語法無效** – 在將模式寫入程式碼前，先使用線上 regex 測試工具驗證。
+- **記憶體洩漏** – 必須關閉 `Parser` 實例，或使用 try‑with‑resources 以確保釋放串流。
+
+## 實務應用
+在 HTML 中使用正則驅動的搜尋可應用於許多實務情境：
+
+1. **資料抽取** – 從大量 HTML 報告中抓取發票號碼、ID 或時間戳記。
+2. **內容過濾** – 自動移除或標記含有禁用關鍵字的區段。
+3. **日誌分析** – 掃描 HTML 格式的日誌以尋找錯誤模式或效能指標。
+4. **ETL 流程** – 將 parser 整合至資料攝取工作流程，以正規化網路抓取的內容。
+
+## 效能考量
+處理大型 HTML 資料集時，請留意以下建議：
+
+- **最佳化正則模式** – 避免過度回溯；盡可能使用原子群組或佔有量詞。
+- **精簡記憶體使用** – 使用 try‑with‑resources 包裹解析，以讓 JVM 及時回收緩衝區。
+- **平行處理** – 利用 Java 的 `ForkJoinPool` 同時搜尋多個文件，在多核心伺服器上線性擴展。
+
+## 常見問答
+
+**Q: 什麼是正則表達式？**
+A: 正則表達式（regex）是一種簡潔、基於模式的語言，用於匹配字串中的字符序列，廣泛應用於驗證、搜尋與文字處理。
+
+**Q: GroupDocs.Parser 能處理非 HTML 檔案嗎？**
+A: 能，它支援超過 70 種格式——包括 PDF、DOCX、XLSX 與 PPTX——因此相同的搜尋邏輯可跨多種文件類型使用。
+
+**Q: 該如何處理解析錯誤？**
+A: 將解析程式碼包在 try‑catch 區塊中，捕獲 `ParserException` 以記錄問題並確保資源關閉。
+
+**Q: 我的 regex 沒有返回結果——哪裡出錯了？**
+A: 再次檢查模式中的轉義字符，確認大小寫敏感設定，並確保目標文字確實存在於 HTML 原始碼中。
+
+**Q: HTML 檔案有大小限制嗎？**
+A: GroupDocs.Parser 可處理最高 2 GB 的檔案；對於極大型的 HTML 檔案，建議將其分割或分段串流，以符合記憶體限制。
+
+## 結論
+透過本指南，您現在已掌握使用 GroupDocs.Parser for Java 內建的強大 regex 引擎 **搜尋 HTML** 文件的方法。您可以快速定位模式、抽取有意義的資料，並將此解決方案整合至更大型的 Java 應用程式或資料管線中。
+
+**下一步：** 嘗試更複雜的模式，結合多個 `SearchOptions`，或將 parser 嵌入 Spring Boot 微服務，以實現即時文字抽取。

+
+## Csomagok importálása
+
+Kezdésként importáljuk a szükséges osztályokat a GroupDocs.Parser‑ből:
+
+`Parser` az elsődleges osztály a dokumentumok betöltéséhez és kezeléséhez. `HighlightOptions` beállítja, hogyan legyen kiemelve a megtalált szöveg. `SearchOptions` határozza meg a keresés viselkedését, például a kis‑ és nagybetű érzékenységet. `SearchResult` egy egyedi találatot reprezentál a dokumentumban.
+
+```java
+import com.groupdocs.parser.Parser;
+import com.groupdocs.parser.search.HighlightOptions;
+import com.groupdocs.parser.search.SearchOptions;
+import com.groupdocs.parser.search.SearchResult;
+```
+
+Ezek az importok lefedik a dokumentumok feldolgozásának, a kiemelési beállítások megadásának és a keresési műveletek végrehajtásának alapvető funkcióit.
+
+## Hogyan működik a keresés‑ és kiemelés‑munkafolyamat?
+
+Töltsd be a PDF‑et, konfiguráld a `HighlightOptions` objektumot, hajtsd végre a `parser.search`‑t, majd iterálj a `SearchResult` gyűjteményen a kiemelt részletek összeállításához. A teljes folyamat kétlépéses: először a parser beolvassa a dokumentum struktúráját; másodszor a keresőmotor átvizsgálja a szövegáramot a megadott beállításokkal. Ez a megközelítés magas teljesítményt biztosít még nagy fájlok esetén is.
+
+## Lépésről‑lépésre útmutató a szöveg kereséséhez kiemelésekkel
+
+Vessük át a folyamatot kezelhető, világos lépésekre bontva. Minden lépés saját magyarázattal rendelkezik, hogy megértsd a miértet és a hogyanot.
+
+### 1. lépés: A Parser inicializálása a dokumentummal
+
+**Mi történik itt?**
+A `Parser` osztály egy példányának létrehozása, amely a dokumentumfájlra mutat, lehetővé teszi a tartalom elérését és elemzését.
+
+`Parser` betölt egy dokumentumot, és metódusokat biztosít a szöveg kinyeréséhez és kereséséhez.
+
+```java
+try (Parser parser = new Parser("path/to/your/document.pdf")) {
+ // your code here
+}
+```
+
+**A valóságban:**
+A `try-with-resources` utasítás biztosítja, hogy a fájl a feldolgozás után megfelelően bezáródjon, elkerülve az erőforrás‑szivárgásokat. Cseréld le a `"path/to/your/document.pdf"`‑t a pontos fájlútvonaladra vagy URL‑re.
+
+### 2. lépés: Kiemelési beállítások konfigurálása
+
+**Miért definiáljunk kiemelési beállításokat?**
+Lehet, hogy szabályozni szeretnéd a keresési találatok megjelenését vagy viselkedését – például a találat körül megjelenő karakterek számát vagy a színt (ha támogatott).
+
+Ebben a példában 15 karakteres kiemelési sugárértéket állítunk be:
+
+`HighlightOptions` határozza meg a kontextus sugárát és a vizuális beállításokat a kiemelt keresési találatokhoz.
+
+```java
+HighlightOptions highlightOptions = new HighlightOptions(15);
+```
+
+Ez a megtalált szöveget körülveszi a környező kontextussal – mintha egy nagyító lenne a kulcsszavak körül – megkönnyítve, hogy hol fordulnak elő a találatok.
+
+### 3. lépés: A keresés végrehajtása a dokumentumban
+
+**Hogyan működik a keresés?**
+A `parser.search` használatával megadod a kulcsszót vagy kifejezést, a keresési beállításokat, majd egy iterálható `SearchResult` objektumgyűjteményt kapsz.
+
+`SearchOptions` konfigurálja a keresési paramétereket, például a kis‑ és nagybetű érzékenységet. `SearchResult` tartalmazza minden találat részleteit, beleértve a megtalált szöveget és annak helyét.
+
+```java
+Iterable results = parser.search("lorem", new SearchOptions(true, false, false, highlightOptions));
+```
+
+A `SearchOptions` konstruktor felbontása:
+
+- `true`: Engedélyezi a kis‑ és nagybetű érzéketlen keresést.
+- `false`: Nem csak teljes szavakra keres.
+- `false`: Nem regex mintákat keres.
+- `highlightOptions`: Átadja a kiemelési konfigurációt.
+
+Ez a beállítás minden `"lorem"` előfordulást keres, figyelmen kívül hagyva a kis‑ és nagybetűket, és kiemelt részletekkel.
+
+### 4. lépés: A keresés támogatásának és eredményeinek kezelése
+
+**Ellenőrizd, hogy a keresés támogatott‑e**
+Néhány formátum nem támogatja a keresést – mindig ellenőrizd:
+
+`parser.isSearchSupported()` egy boolean értéket ad vissza, amely jelzi, hogy a betöltött dokumentumformátum engedélyezi‑e a szövegkeresést.
+
+```java
+if (results == null) {
+ System.out.println("Search isn't supported in this document format.");
+ return;
+}
+```
+
+**Minden keresési találat feldolgozása**
+Iterálj az eredményeken a megfelelő részletek kiemelésével és megjelenítésével:
+
+`SearchResult` objektumok hozzáférést biztosítanak a megtalált kifejezéshez és a környező kontextushoz.
+
+```java
+for (SearchResult result : results) {
+ String snippet = String.format("%s%s%s",
+ result.getLeftHighlightItem().getText(),
+ result.getText(),
+ result.getRightHighlightItem().getText());
+ System.out.println(snippet);
+}
+```
+
+## Gyakori problémák és megoldások
+
+| Probléma | Ok | Megoldás |
+|----------|----|----------|
+| **Nincs eredmény** | A dokumentum formátuma nem kereshető | Ellenőrizd, hogy a `parser.isSearchSupported()` `true`‑t ad vissza. |
+| **A kiemelési sugár túl kicsi** | Az alapértelmezett sugár 10 karakter | Növeld a sugár értékét a `HighlightOptions`‑ban (pl. `new HighlightOptions(20)`). |
+| **Memóriahiány hiba nagy PDF‑eknél** | Az egész fájl a memóriába töltődik | Használd a `Parser`‑t streaming módban vagy dolgozd fel a fájlt darabokban; a GroupDocs.Parser már hatékonyan streameli a nagy fájlokat. |
+| **A kis‑ és nagybetű érzékenység nem a várt módon működik** | `caseSensitive` flag hibás beállítás | Győződj meg róla, hogy a `SearchOptions(true, …)` a megfelelő boolean értéket állítja be a kis‑ és nagybetű érzéketlen kereséshez. |
+
+## Gyakran Ismételt Kérdések
+
+**Q: Kereshetek több kulcsszót egyszerre?**
+A: Nem közvetlenül; iterálj minden kulcsszón, vagy építs regex mintát, amely minden kívánt kifejezést lefed.
+
+**Q: A kiemelési sugár minden dokumentumformátumra hat?**
+A: A legtöbb támogatott formátumnál a sugár egységesen működik; néhány képalapú formátum figyelmen kívül hagyja, mivel nincs natív szövegrétege.
+
+**Q: Módosíthatom a kiemelés színét?**
+A: A `HighlightOptions` a kontextus sugárát szabályozza; a vizuális színek a PDF‑megjelenítőn múlnak, nem a parseren.
+
+**Q: Alapértelmezés szerint a keresés kis‑ és nagybetű érzékeny?**
+A: Nem. A `caseSensitive` `false`‑ra állításával a `SearchOptions`‑ban a keresés kis‑ és nagybetű érzéketlen lesz.
+
+**Q: Működik ez beolvasott képekkel vagy csak szöveges fájlokkal?**
+A: A keresés szöveges dokumentumokon működik. Beolvasott képekhez OCR képességre van szükség, amelyet a GroupDocs OCR külön modulként biztosít.

+# Hogyan használjunk regexet EPUB szövegkereséshez a GroupDocs.Parser segítségével
+
+Ebben a gyakorlati útmutatóban megtudja, **hogyan kell használni a regexet**, hogy szöveget keressen EPUB fájlokban a GroupDocs.Parser for Java segítségével. Akár digitális könyvtár indexelőt épít, akár specifikus kifejezéseket kell megtaláljon több ezer e‑könyvben, a reguláris kifejezések keresésének elsajátítása időt takarít meg és javítja a pontosságot. Végigvezetünk a beállításon, a kulcsfontosságú osztályokon és a gyakorlati mintákon, miközben **hogyan kell hatékonyan keresni epub** fájlokban.
+
+## Gyors válaszok
+- **Melyik könyvtár elemzi az EPUB-ot Java-ban?** GroupDocs.Parser for Java.
+- **Használhatok regexet EPUB kereséshez?** Igen – az API elfogadja a Java Pattern objektumokat.
+- **Hogyan hajtsak végre kis- és nagybetű érzékeny keresést?** Állítsa be a `SearchOptions.setIgnoreCase(false)` értéket.
+- **Szükségem van licencre?** Egy ingyenes próba a teszteléshez megfelelő; egy teljes licenc eltávolítja a korlátokat.
+- **Melyik Java verzió szükséges?** JDK 8 vagy újabb.
+
+## Mi az a GroupDocs.Parser?
+A GroupDocs.Parser egy Java könyvtár, amely szöveget, képeket és metaadatokat nyer ki több mint 50 dokumentumformátumból, beleértve az EPUB-ot is. Magas szintű `Parser` osztályt biztosít, amely elrejti a fájlkezelést, így a keresési logikára koncentrálhat ahelyett, hogy az alacsony szintű elemzéssel foglalkozna. A könyvtár hatékonyan streameli a tartalmat, támogatja a memória‑korlátos környezeteket, és beépített keresési funkciókat kínál, amelyek közvetlenül a feldolgozott szövegen működnek.
+
+## Miért használjunk regexet a GroupDocs.Parser-rel EPUB-hoz?
+- **Széles körű formátumtámogatás:** Kezel 50+ bemeneti formátumot, köztük az EPUB-ot, külső konvertálók nélkül.
+- **Memóriahatékony feldolgozás:** Streameli a tartalmat, lehetővé téve több száz oldalas EPUB-ok keresését anélkül, hogy az egész fájlt RAM-ba töltené.
+- **Pontos mintakeresés:** A regex lehetővé teszi teljes szavak, kifejezések vagy összetett minták (pl. dátumok, ISBN-ek) megtalálását egyetlen hívásban.
+
+## Előfeltételek
+- **Java Development Kit (JDK) 8+** telepítve és konfigurálva az IDE‑ben vagy a build eszközben.
+- **GroupDocs.Parser for Java** könyvtár (elérhető Maven‑on vagy közvetlen letöltéssel).
+- Alapvető ismeretek a Java szintaxisról és a reguláris kifejezésekről.
+
+## Hogyan használjunk regexet szöveg keresésére EPUB fájlokban?
+Töltse be az EPUB-ot a `new Parser("book.epub")` segítségével, és hívja meg a `search`-t egy lefordított `Pattern` használatával. Ez a kétszakaszos megközelítés elkülöníti a fájl betöltését a minta végrehajtásától, biztosítva az optimális teljesítményt még nagy gyűjtemények esetén is.
+
+### 1. lépés: A Parser inicializálása
+A `Parser` osztály a belépési pont az EPUB fájl betöltéséhez és kezeléséhez.
+```java
+// ```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/parser/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5
+
+
+```
+```
+
+### 2. lépés: Regex minta felépítése
+A Java `Pattern` osztálya lefordítja a reguláris kifejezést. Például, hogy megtaláljon minden olyan szót, amely a „list” szóval kezdődik egy szóköz karakter után, használja a `\\slist\\w*` kifejezést.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+// Initialize Parser object with an EPUB file path
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.epub")) {
+ // Your code here
+}
+```
+```
+
+### 3. lépés: Keresési beállítások konfigurálása
+`SearchOptions` konfigurálja, hogyan működik a keresés, például a kis- és nagybetű érzékenység és a fuzzy (könyvjelző) egyezés.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+String epubFilePath = "YOUR_DOCUMENT_DIRECTORY/sample.epub";
+
+try (Parser parser = new Parser(epubFilePath)) {
+ // Further processing steps go here
+}
+```
+```
+
+### 4. lépés: A keresés végrehajtása
+`SearchResult` egyetlen egyezést reprezentál, beleértve a szöveget, az oldalszámot és a karaktereltolásokat.
+```java
+// ```java
+String regexPattern = \\slist; // Matches any word preceded by whitespace and 'list'
+```
+```
+
+### 5. lépés: Az eredmények feldolgozása
+Iteráljon a `SearchResult` gyűjteményen, hogy naplózza az egyezéseket, adatbázisba mentse őket, vagy elindítson downstream munkafolyamatokat, mint például indexelés vagy riasztás.
+```java
+// ```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options for search
+SearchOptions options = new SearchOptions(true /* case match */, false /* whole word */, true /* fuzzy */);
+```
+```
+
+## Hogyan hajtsunk végre kis- és nagybetű érzékeny keresést Java-ban?
+Állítsa be a `SearchOptions.setIgnoreCase(false)` értéket a pontos nagybetű-érzékeny egyezés érvényesítéséhez. Ez elengedhetetlen azonosítók, kódrészletek vagy márkanevek keresésekor, amelyeknek meg kell tartaniuk az eredeti nagybetűhasználatot.
+
+## Gyakori felhasználási esetek
+1. **Digitális könyvtár indexelése:** Automatikusan generálható kereshető indexek több ezer EPUB címhez.
+2. **Tartalom kurálása:** Tematikus szakaszok (pl. „5. fejezet”) megtalálása több könyvben kutatási célokra.
+3. **Adatbányászat:** Strukturált entitások, például ISBN-ek, dátumok vagy szerzőnevek kinyerése testreszabott regex mintákkal.
+4. **E‑learning integráció:** A kurzusplatformok bővítése azonnali teljes szöveges keresési képességekkel a kurzus anyag PDF és EPUB fájljaihoz.
+
+## Teljesítmény tippek
+- **Optimalizálja a regex mintákat:** Előnyben részesítse az egyszerű karakterosztályokat a visszalépés‑intenzív konstrukciókkal szemben, hogy alacsony CPU‑használatot biztosítson.
+- **Nagy EPUB-ok darabolása:** Dolgozza fel a fejezeteket egyenként, ha a fájl meghaladja a 200 MB-ot, hogy elkerülje a memória csúcsokat.
+- **Gyakori lekérdezések gyorsítótárazása:** Tárolja a népszerű minták (pl. gyakori kulcsszavak) eredményeit egy könnyű, memória‑alapú térképen.
+
+## Gyakran feltett kérdések
+
+**K: Mi a különbség a `search` és az `extractText` között?**
+V: A `search` regex mintát alkalmaz, és csak a megfelelő részleteket adja vissza, míg az `extractText` a teljes dokumentumtartalmat adja vissza szűrés nélkül.
+
+**K: Kereshetek több EPUB fájlt egy hívásban?**
+V: Egyetlen API hívás nem dolgoz fel kötegelt fájlokat, de ciklusba teheti a fájllistát, újrahasználva ugyanazt a `Pattern`‑t és `SearchOptions`‑t minden fájlhoz.
+
+**K: Hogyan működik a fuzzy keresés?**
+V: Engedélyezze a fuzzy módot a `SearchOptions`‑ban, hogy legfeljebb két szerkesztéses Levenshtein távolságot engedélyezzen, ami elkapja a helyesírási hibákat és kisebb eltéréseket.
+
+**K: Van korlátozás a dokumentum méretére?**
+V: A GroupDocs.Parser akár 500 MB‑os EPUB-okat is képes kezelni; nagyobb fájlokat fel kell darabolni vagy manuálisan streamelni.
+
+**K: Szükségem van licencre a fejlesztéshez?**
+V: Az ingyenes próba teljes API hozzáférést biztosít használati vízjellel; egy állandó licenc eltávolítja a korlátozásokat és kereskedelmi jogokat biztosít.

+# Hogyan keressünk HTML-t a GroupDocs.Parser for Java segítségével
+
+A hatalmas HTML-fájlokban való keresés specifikus minták után olyan, mintha egy tűt keresnénk egy szénakazalban. A **How to search html** hatékony végrehajtása gyakori kérdés a Java fejlesztők körében, akiknek adatot kell kinyerniük, tartalmat szűrniük vagy automatizálniuk kell a jelentéselemzést. Ebben az útmutatóban egy gyakorlati, regex‑alapú megközelítést ismerhetsz meg, amelyet a **GroupDocs.Parser for Java** biztosít — a beállítástól a hibakeresésig — így magabiztosan megtalálhatod a kívánt szövegmintát a HTML-dokumentumokban.
+
+## Gyors válaszok
+- **Melyik könyvtár kezeli a HTML regex keresést Java-ban?** GroupDocs.Parser for Java.
+- **Szükségem van licencre a fejlesztéshez?** A ingyenes próba a teszteléshez működik; a termeléshez állandó licenc szükséges.
+- **Melyik Java verzió szükséges?** Java 8 vagy újabb (JDK 11 ajánlott).
+- **Kereshetek több fájlt egyszerre?** Igen — a parser hívást egy ciklusba ágyazva vagy Java stream-ekkel.
+- **Milyen teljesítményre számíthatok?** A GroupDocs.Parser 500 oldalas HTML-fájlokat kevesebb, mint 2 másodperc alatt dolgoz fel egy tipikus szerveren.
+
+## Mi az a „how to search html” regex-szel?
+**„How to search html”** arra utal, hogy reguláris kifejezéseket (regex) használunk szövegminták megtalálására a HTML jelölőnyelvben. Ez a technika lehetővé teszi szavak, számok vagy egyedi címkék pontos megtalálását anélkül, hogy az egész DOM-fát parse-oznánk. A regex közvetlenül a nyers HTML-forrásra alkalmazva a fejlesztők gyorsan kinyerhetnek specifikus adatokat, ellenőrizhetik a tartalmat vagy szűrhetik a szekciókat, így könnyű alternatívát nyújt a teljes DOM-parszoláshoz.
+
+## Miért használjuk a GroupDocs.Parser for Java-t regex keresésekhez?
+A GroupDocs.Parser **70+** bemeneti és kimeneti formátumot támogat — köztük HTML, DOCX, XLSX és PDF — miközben több száz oldalas dokumentumokat dolgoz fel anélkül, hogy a teljes fájlt a memóriába töltené. A natív `SearchOptions` osztály lehetővé teszi a reguláris kifejezések engedélyezését, a kis- és nagybetű érzékenység szabályozását, valamint az eredmények korlátozását, így gyors és memóriahatékony vizsgálatot biztosít.
+

+
+**Inicializálás**
+Miután a könyvtár hozzá lett adva, inicializáld a Java alkalmazásodat a GroupDocs.Parser használatához:
+
+```java
+import com.groupdocs.parser.Parser;
+
+public class SetupExample {
+ public static void main(String[] args) {
+ String filePath = "path/to/your/document.html";
+ try (Parser parser = new Parser(filePath)) {
+ // Initialization complete, ready to parse and search!
+ } catch (Exception e) {
+ e.printStackTrace();
+ }
+ }
+}
+```
+
+## Hogyan keressünk HTML-t a GroupDocs.Parser for Java segítségével?
+Töltsd be a HTML-fájlt a `Parser` osztállyal, és hajts végre egy regex keresést mindössze két kódsorban. A `Parser` osztály a belépési pont, amely beolvassa és parse-olja a támogatott dokumentumtípusokat, és metódusokat biztosít a szövegkinyeréshez és kereséshez. A `SearchOptions` konfigurálásával a parsernek jelezheted, hogy a mintádat reguláris kifejezésként kezelje, opcionálisan engedélyezve a kis- és nagybetű érzékeny vagy teljes szavas egyezést.
+
+### Lépésről‑lépésre megvalósítás
+
+### 1. lépés: Definiáld a reguláris kifejezés mintádat
+Először készítsd el a regex mintát, amely megfelel a szükséges szövegnek. Ebben a példában olyan szavakat keresünk, amelyek **„Sub”**-val kezdődnek, majd egy számjegyet követnek (pl. `Sub1`, `Sub9`).
+
+```java
+String regexPattern = "Sub[0-9]";
+```
+
+### 2. lépés: Állítsd be a keresési beállításokat
+`SearchOptions` egy konfigurációs objektum, amely meghatározza a keresés viselkedését, például a regex módot és a kis- és nagybetű érzékenységet.
+Állítsd be a `SearchOptions` objektumot, hogy aktiváld a regex módot, beállítsd a kis- és nagybetű érzékenységet, és döntsd el, hogy csak teljes szavakat egyeztesz-e. A `SearchOptions` egy konfigurációs tároló, amely megmondja a parsernek, hogyan hajtsa végre a keresést.
+
+```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options: case-sensitive, whole word, use regex
+SearchOptions options = new SearchOptions(true, false, true);
+```
+
+### 3. lépés: Hajtsd végre a keresést
+Hívd meg a `search` metódust egy `Parser` példányon, átadva a HTML-fájl útvonalát, a mintát és a beállításokat. A metódus egy `SearchResult` objektumok gyűjteményét adja vissza, amelyek mindegyike tartalmazza a megtalált szöveget és annak helyét a dokumentumban.
+
+```java
+import com.groupdocs.parser.data.SearchResult;
+
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.html")) {
+ Iterable results = parser.search(regexPattern, options);
+
+ for (SearchResult result : results) {
+ System.out.println(String.format("At %d: %s", result.getPosition(), result.getText()));
+ }
+} catch (Exception e) {
+ e.printStackTrace();
+}
+```
+
+**Kulcsfontosságú konfigurációs beállítások**
+- **Case Sensitivity** – állítsd `true`-ra a pontos kis- és nagybetű egyezéshez.
+- **Whole Word Search** – `false` részleges egyezéseket is tartalmaz.
+- **Use Regular Expressions** – `true`-nak kell lennie a regex feldolgozás engedélyezéséhez.
+
+## Gyakori problémák és megoldások
+- **Incorrect file path** – ellenőrizd, hogy a HTML-fájl elérhető-e az alkalmazásod munkakönyvtárából.
+- **Invalid regex syntax** – teszteld a mintádat egy online regex tesztelővel, mielőtt a kódban használnád.
+- **Memory leaks** – mindig zárd le a `Parser` példányt, vagy használj try‑with‑resources blokkot, hogy a stream-ek felszabaduljanak.
+
+## Gyakorlati alkalmazások
+A regex‑alapú keresések alkalmazása HTML-ben számos valós életbeli forgatókönyvet nyit meg:
+1. **Data Extraction** – húzd ki a számlaszámokat, azonosítókat vagy időbélyegeket a tömeges HTML-jelentésekből.
+2. **Content Filtering** – automatikusan távolíts el vagy jelölj meg szekciókat, amelyek tiltott kulcsszavakat tartalmaznak.
+3. **Log Analysis** – vizsgáld meg a HTML‑formátumú naplókat hibaminták vagy teljesítménymutatók keresésére.
+4. **ETL Pipelines** – integráld a parse‑rt adatbeviteli munkafolyamatokba, amelyek normalizálják a web‑kaparásból származó tartalmat.
+
+## Teljesítménybeli szempontok
+Nagy HTML-korpuszok kezelésekor tartsd szem előtt ezeket a tippeket:
+- **Optimize regex patterns** – kerüld a túlzott backtracking-et; használj atomcsoportokat vagy birtokló kvantorokat, ha lehetséges.
+- **Streamline memory usage** – a parse‑t egy try‑with‑resources blokkba ágyazva, a JVM gyorsan felszabadíthatja a puffereket.
+- **Parallel processing** – használd a Java `ForkJoinPool`-ját, hogy egyszerre több dokumentumot keress, lineárisan skálázva a többmagos szervereken.
+
+## Gyakran Ismételt Kérdések
+
+**Q: Mi az a reguláris kifejezés?**
+A: A reguláris kifejezés (regex) egy tömör, mintákon alapuló nyelv karakter sorozatok egyezésére karakterláncokban, széles körben használják validálásra, keresésre és szövegmanipulációra.
+
+**Q: Kezelhet a GroupDocs.Parser nem‑HTML fájlokat is?**
+A: Igen, több mint 70 formátumot támogat — köztük PDF, DOCX, XLSX és PPTX — így ugyanaz a keresési logika különböző dokumentumtípusoknál is működik.
+
+**Q: Hogyan kezeljem a parse‑olási hibákat?**
+A: Tedd a parse‑olási kódot try‑catch blokkba, elkapva a `ParserException`-t, hogy naplózd a problémát és biztosítsd az erőforrások lezárását.
+
+**Q: A regex‑em nem ad eredményt — mi a hiba?**
+A: Ellenőrizd újra a mintát az escape karakterek miatt, a kis‑ és nagybetű érzékenység beállításait, és győződj meg róla, hogy a cél szöveg valóban létezik a HTML-forrásban.
+
+**Q: Van méretkorlát a HTML-fájloknál?**
+A: A GroupDocs.Parser akár 2 GB-ig terjedő fájlokat is képes feldolgozni; rendkívül nagy HTML-fájlok esetén fontold meg a felosztást vagy a szekciók stream‑elését, hogy a memóriahatárokon belül maradj.
+
+## Következtetés
+Ezzel az útmutatóval most már tudod, hogyan **how to search html** dokumentumokat keresni a GroupDocs.Parser for Java beépített, erőteljes regex motorjával. Gyorsan megtalálhatod a mintákat, kinyerheted a lényeges adatokat, és integrálhatod a megoldást nagyobb Java alkalmazásokba vagy adatcsövekbe.

+# Pemrosesan PDF Java: Pencarian & Penyorotan dengan GroupDocs
+
+Pernah merasa tenggelam dalam lautan dokumen—PDF, file Word, atau format lainnya—dan berharap Anda dapat dengan mudah menemukan kata atau frasa tertentu? **Java PDF processing** membuat hal itu menjadi mungkin. Dalam panduan ini Anda akan belajar cara mencari teks di dalam PDF dan menghasilkan potongan yang disorot menggunakan **GroupDocs.Parser for Java**. Baik Anda membangun alat analisis dokumen atau mengotomatisasi peninjauan konten, langkah‑langkah di bawah ini memberikan solusi yang jelas dan siap produksi.
+
+## Jawaban Cepat
+- **Library mana yang menangani pencarian teks PDF di Java?** GroupDocs.Parser for Java.
+- **Apakah saya memerlukan lisensi untuk pengembangan?** Lisensi sementara berfungsi untuk pengujian; lisensi penuh diperlukan untuk produksi.
+- **Bisakah saya menyorot beberapa kemunculan sekaligus?** Ya—atur radius sorotan dan iterasi hasil.
+- **Apakah pencarian bersifat case‑sensitive?** Secara default tidak case‑sensitive; Anda dapat mengubahnya melalui `SearchOptions`.
+- **Format apa yang didukung?** Lebih dari 50 format input dan output, termasuk PDF, DOCX, XLSX, PPTX, HTML, dan gambar.
+
+## Apa itu pemrosesan PDF Java?
+`Java PDF processing` adalah sekumpulan operasi programatik—seperti mengekstrak, mencari, dan menyorot teks—yang dilakukan pada file PDF menggunakan pustaka Java. Dengan GroupDocs.Parser Anda dapat mencari dokumen apa pun yang didukung, mengambil konteks sekitarnya, dan menerapkan sorotan visual, semuanya tanpa membuka file di penampil. Kemampuan ini memungkinkan Anda membangun arsip yang cepat, dapat dicari, dan pipeline peninjauan otomatis yang dapat menangani ribuan halaman per dokumen.
+
+## Mengapa menggunakan GroupDocs.Parser untuk pemrosesan PDF Java?
+GroupDocs.Parser mendukung **lebih dari 50 format file** dan dapat memproses **PDF berukuran ratusan halaman** tanpa memuat seluruh file ke memori, mengurangi penggunaan RAM hingga **70 %** dibandingkan pendekatan naïf. Mesin pencariannya mengembalikan offset yang tepat, memungkinkan Anda membangun sorotan UI khusus atau mengekspor hasil ke sistem lain. Pustaka ini aktif dipelihara, kompatibel dengan Java 8+, dan menawarkan artefak Maven serta Gradle untuk integrasi mudah.
+
+## Prasyarat
+
+Sebelum kita mulai, pastikan Anda memiliki hal‑hal berikut siap:
+
+- **Lingkungan Pengembangan Java**: JDK 8+ terpasang.
+- **Maven atau Gradle**: Untuk manajemen dependensi dan penyiapan proyek.
+- **Pustaka GroupDocs.Parser untuk Java**: Unduh atau tambahkan melalui dependensi.
+- **Dokumen contoh**: PDF atau teks untuk diuji pencariannya.
+- **Pengetahuan dasar Java**: Familiaritas dengan kelas, metode, dan penanganan file.
+
+Jika Anda belum memiliki pustaka tersebut, Anda dapat mengunduh versi terbaru dari [GroupDocs Downloads](https://releases.groupdocs.com/parser/java/) atau menambahkannya melalui Maven:
+
+```xml
+
+ com.groupdocs
+ groupdocs-parser
+ 21.12
+
+```
+
+## Impor Paket
+
+Untuk memulai, mari impor kelas‑kelas penting dari GroupDocs.Parser:
+
+`Parser` adalah kelas utama yang digunakan untuk memuat dan berinteraksi dengan dokumen. `HighlightOptions` mengonfigurasi cara teks yang cocok disorot. `SearchOptions` mendefinisikan perilaku pencarian seperti sensitivitas huruf. `SearchResult` mewakili satu kecocokan yang ditemukan dalam dokumen.
+
+```java
+import com.groupdocs.parser.Parser;
+import com.groupdocs.parser.search.HighlightOptions;
+import com.groupdocs.parser.search.SearchOptions;
+import com.groupdocs.parser.search.SearchResult;
+```
+
+Impor ini mencakup fungsionalitas inti untuk parsing dokumen, pengaturan opsi sorotan, dan pelaksanaan operasi pencarian.
+
+## Bagaimana alur kerja pencarian dan penyorotan bekerja?
+
+Muat PDF Anda, konfigurasikan objek `HighlightOptions`, jalankan `parser.search`, lalu iterasi koleksi `SearchResult` untuk membangun potongan yang disorot. Seluruh proses berjalan dalam dua langkah: pertama, parser membaca struktur dokumen; kedua, mesin pencarian memindai aliran teks dengan menerapkan opsi yang Anda tentukan. Pendekatan ini memastikan kinerja tinggi bahkan pada file besar.
+
+## Panduan Langkah-demi-Langkah untuk Mencari Teks dengan Penyorotan
+
+Mari ikuti proses yang dibagi menjadi langkah‑langkah jelas. Setiap langkah memiliki penjelasan tersendiri untuk membantu Anda memahami mengapa dan bagaimana.
+
+### Langkah 1: Inisialisasi Parser dengan Dokumen Anda
+
+**Apa yang terjadi di sini?**
+Membuat instance kelas `Parser` yang terhubung ke file dokumen Anda memungkinkan Anda mengakses dan menganalisis isinya.
+
+`Parser` memuat dokumen dan menyediakan metode untuk ekstraksi teks serta pencarian.
+
+```java
+try (Parser parser = new Parser("path/to/your/document.pdf")) {
+ // your code here
+}
+```
+
+**Sebenarnya:**
+Pernyataan `try-with-resources` memastikan file Anda ditutup dengan benar setelah pemrosesan, mencegah kebocoran sumber daya. Ganti `"path/to/your/document.pdf"` dengan jalur file atau URL yang tepat.
+
+### Langkah 2: Atur Opsi Penyorotan
+
+**Mengapa mengatur opsi penyorotan?**
+Anda mungkin ingin mengontrol tampilan atau perilaku cara hasil pencarian disorot—misalnya jumlah karakter yang ditampilkan di sekitar kecocokan atau warna (jika didukung).
+
+Dalam contoh ini, kami mengatur radius sorotan menjadi 15 karakter:
+
+`HighlightOptions` menentukan radius konteks dan pengaturan visual untuk sorotan hasil pencarian.
+
+```java
+HighlightOptions highlightOptions = new HighlightOptions(15);
+```
+
+Ini membungkus teks yang ditemukan dengan konteks sekitarnya—seperti kaca pembesar di sekitar kata kunci Anda—memudahkan melihat di mana kecocokan terjadi.
+
+### Langkah 3: Lakukan Pencarian di Dokumen
+
+**Bagaimana cara kerja pencarian?**
+Dengan menggunakan `parser.search`, Anda menentukan kata kunci atau frasa, opsi pencarian, dan kemudian mendapatkan koleksi iterabel dari objek `SearchResult`.
+
+`SearchOptions` mengonfigurasi parameter pencarian seperti sensitivitas huruf. `SearchResult` berisi detail setiap kecocokan, termasuk teks yang cocok dan lokasinya.
+
+```java
+Iterable results = parser.search("lorem", new SearchOptions(true, false, false, highlightOptions));
+```
+
+Memecah konstruktor `SearchOptions`:
+
+- `true`: Mengaktifkan pencarian tidak case‑sensitive.
+- `false`: Tidak mencocokkan hanya kata lengkap.
+- `false`: Tidak mencari pola regex.
+- `highlightOptions`: Mengirimkan konfigurasi sorotan kami.
+
+Pengaturan ini mencari semua kemunculan `"lorem"` tanpa memperhatikan huruf besar/kecil, dan menampilkan potongan yang disorot.
+
+### Langkah 4: Tangani Dukungan Pencarian dan Hasil
+
+**Periksa apakah pencarian didukung**
+Beberapa format mungkin tidak mendukung pencarian — selalu pastikan:
+
+`parser.isSearchSupported()` mengembalikan nilai boolean yang menunjukkan apakah format dokumen yang dimuat memungkinkan pencarian teks.
+
+```java
+if (results == null) {
+ System.out.println("Search isn't supported in this document format.");
+ return;
+}
+```
+
+**Proses setiap hasil pencarian**
+Loop melalui hasil untuk mengekstrak dan menampilkan potongan yang cocok dengan sorotan:
+
+Objek `SearchResult` memberikan akses ke frasa yang cocok dan konteks sekitarnya.
+
+```java
+for (SearchResult result : results) {
+ String snippet = String.format("%s%s%s",
+ result.getLeftHighlightItem().getText(),
+ result.getText(),
+ result.getRightHighlightItem().getText());
+ System.out.println(snippet);
+}
+```
+
+## Masalah Umum dan Solusinya
+
+| Masalah | Alasan | Solusi |
+|-------|--------|-----|
+| **Tidak ada hasil yang dikembalikan** | Format dokumen tidak dapat dicari | Verifikasi `parser.isSearchSupported()` mengembalikan `true`. |
+| **Radius sorotan terasa terlalu kecil** | Radius default adalah 10 karakter | Tingkatkan radius di `HighlightOptions` (mis., `new HighlightOptions(20)`). |
+| **Kesalahan out‑of‑memory pada PDF besar** | Seluruh file dimuat ke memori | Gunakan `Parser` dengan mode streaming atau proses file dalam potongan; GroupDocs.Parser sudah melakukan streaming file besar secara efisien. |
+| **Sensitivitas huruf tidak berperilaku seperti yang diharapkan** | Flag `caseSensitive` salah diatur | Pastikan `SearchOptions(true, …)` mengatur boolean yang tepat untuk ketidaksensitifan huruf. |
+
+## Pertanyaan yang Sering Diajukan
+
+**Q: Bisakah saya mencari beberapa kata kunci sekaligus?**
+A: Tidak secara langsung; iterasi setiap kata kunci atau buat pola regex yang mencakup semua istilah yang diinginkan.
+
+**Q: Apakah radius sorotan memengaruhi semua format dokumen?**
+A: Untuk sebagian besar format yang didukung radius berfungsi secara seragam; beberapa format berbasis gambar mengabaikannya karena tidak memiliki lapisan teks asli.
+
+**Q: Bisakah saya mengubah warna sorotan?**
+A: `HighlightOptions` mengontrol radius konteks; warna visual tergantung pada penampil PDF yang Anda gunakan, bukan parser itu sendiri.
+
+**Q: Apakah pencarian bersifat case‑sensitive secara default?**
+A: Tidak. Dengan mengatur `caseSensitive` ke `false` dalam `SearchOptions`, pencarian menjadi tidak sensitif huruf.
+
+**Q: Apakah ini bekerja dengan gambar yang dipindai atau hanya file berbasis teks?**
+A: Pencarian berfungsi pada dokumen berbasis teks. Untuk gambar yang dipindai Anda memerlukan kemampuan OCR, yang disediakan oleh modul terpisah GroupDocs OCR.

+
+Dalam panduan praktis ini Anda akan menemukan **cara menggunakan regex** untuk mencari teks di dalam file EPUB menggunakan GroupDocs.Parser untuk Java. Baik Anda sedang membangun pengindeks perpustakaan digital atau perlu menemukan frasa tertentu di antara ribuan e‑book, menguasai pencarian dengan regular‑expression akan menghemat waktu dan meningkatkan akurasi. Kami akan membahas pengaturan, kelas utama, dan pola praktis, sekaligus mencakup **cara mencari epub** secara efisien.
+
+## Jawaban Cepat
+- **Library apa yang mem-parsing EPUB di Java?** GroupDocs.Parser untuk Java.
+- **Apakah saya dapat menggunakan regex untuk pencarian EPUB?** Ya – API menerima objek Java Pattern.
+- **Bagaimana melakukan pencarian sensitif huruf?** Set `SearchOptions.setIgnoreCase(false)`.
+- **Apakah saya memerlukan lisensi?** Versi percobaan gratis dapat digunakan untuk pengujian; lisensi penuh menghapus batasan.
+- **Versi Java apa yang diperlukan?** JDK 8 atau lebih tinggi.
+
+## Apa itu GroupDocs.Parser?
+GroupDocs.Parser adalah pustaka Java yang mengekstrak teks, gambar, dan metadata dari lebih dari 50 format dokumen, termasuk EPUB. Ia menyediakan kelas `Parser` tingkat tinggi yang mengabstraksi penanganan file, memungkinkan Anda fokus pada logika pencarian daripada parsing tingkat rendah. Pustaka ini men‑stream konten secara efisien, mendukung lingkungan dengan memori terbatas, dan menawarkan kemampuan pencarian bawaan yang bekerja langsung pada teks yang diparse.
+
+## Mengapa Menggunakan Regex dengan GroupDocs.Parser untuk EPUB?
+- **Dukungan format luas:** Menangani lebih dari 50 format input, termasuk EPUB, tanpa konverter eksternal.
+- **Pemrosesan hemat memori:** Men‑stream konten, memungkinkan EPUB dengan ratusan halaman untuk dicari tanpa memuat seluruh file ke RAM.
+- **Pencocokan pola yang tepat:** Regex memungkinkan Anda menemukan kata lengkap, frasa, atau pola kompleks (mis., tanggal, ISBN) dalam satu panggilan.
+
+## Prasyarat
+- **Java Development Kit (JDK) 8+** terinstal dan dikonfigurasi di IDE atau alat build Anda.
+- **GroupDocs.Parser untuk Java** (tersedia via Maven atau unduhan langsung).
+- Familiaritas dasar dengan sintaks Java dan konsep regular‑expression.
+
+## Cara Menggunakan Regex untuk Mencari Teks dalam File EPUB?
+Muat EPUB Anda dengan `new Parser("book.epub")` dan panggil `search` menggunakan `Pattern` yang telah dikompilasi. Pendekatan dua langkah ini memisahkan pemuatan file dari eksekusi pola, memastikan kinerja optimal bahkan pada koleksi besar.
+
+### Langkah 1: Inisialisasi Parser
+Kelas `Parser` adalah titik masuk untuk memuat dan menangani file EPUB.
+```java
+// ```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/parser/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5
+
+
+```
+```
+
+### Langkah 2: Membuat Pola Regex
+Kelas `Pattern` Java mengompilasi regular expression. Misalnya, untuk menemukan kata apa pun yang dimulai dengan “list” setelah karakter spasi, gunakan `\\slist\\w*`.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+// Initialize Parser object with an EPUB file path
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.epub")) {
+ // Your code here
+}
+```
+```
+
+### Langkah 3: Mengonfigurasi Opsi Pencarian
+`SearchOptions` mengonfigurasi cara kerja pencarian, seperti sensitivitas huruf dan pencocokan fuzzy.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+String epubFilePath = "YOUR_DOCUMENT_DIRECTORY/sample.epub";
+
+try (Parser parser = new Parser(epubFilePath)) {
+ // Further processing steps go here
+}
+```
+```
+
+### Langkah 4: Menjalankan Pencarian
+`SearchResult` mewakili satu kecocokan, termasuk teks, nomor halaman, dan offset karakter.
+```java
+// ```java
+String regexPattern = \\slist; // Matches any word preceded by whitespace and 'list'
+```
+```
+
+### Langkah 5: Memproses Hasil
+Iterasikan koleksi `SearchResult` untuk mencatat kecocokan, menyimpannya ke basis data, atau memicu alur kerja downstream seperti pengindeksan atau peringatan.
+```java
+// ```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options for search
+SearchOptions options = new SearchOptions(true /* case match */, false /* whole word */, true /* fuzzy */);
+```
+```
+
+## Cara Melakukan Pencarian Sensitif Huruf di Java?
+Set `SearchOptions.setIgnoreCase(false)` untuk menegakkan pencocokan huruf yang tepat. Ini penting saat mencari identifier, potongan kode, atau nama merek yang harus mempertahankan kapitalisasi aslinya.
+
+## Kasus Penggunaan Umum
+1. **Pengindeksan Perpustakaan Digital:** Secara otomatis menghasilkan indeks yang dapat dicari untuk ribuan judul EPUB.
+2. **Kurasi Konten:** Menemukan bagian tematik (mis., “Chapter 5”) di banyak buku untuk penelitian.
+3. **Data Mining:** Mengekstrak entitas terstruktur seperti ISBN, tanggal, atau nama penulis menggunakan pola regex yang disesuaikan.
+4. **Integrasi E‑Learning:** Meningkatkan platform kursus dengan kemampuan pencarian teks penuh instan untuk materi kursus dalam format PDF dan EPUB.
+
+## Tips Kinerja
+- **Optimalkan pola regex:** Lebih pilih kelas karakter sederhana daripada konstruksi yang berat pada back‑tracking untuk menjaga penggunaan CPU tetap rendah.
+- **Bagi EPUB besar:** Proses bab secara terpisah jika file melebihi 200 MB untuk menghindari lonjakan memori.
+- **Cache kueri sering:** Simpan hasil pola populer (mis., kata kunci umum) dalam peta ringan di memori.
+
+## Pertanyaan yang Sering Diajukan
+
+**Q: Apa perbedaan antara `search` dan `extractText`?**
+A: `search` menerapkan pola regex dan mengembalikan hanya fragmen yang cocok, sementara `extractText` mengembalikan seluruh konten dokumen tanpa penyaringan.
+
+**Q: Bisakah saya mencari beberapa file EPUB dalam satu panggilan?**
+A: Tidak ada panggilan API tunggal yang memproses batch, tetapi Anda dapat melakukan loop pada daftar file, menggunakan kembali `Pattern` dan `SearchOptions` yang sama untuk setiap file.
+
+**Q: Bagaimana cara kerja pencarian fuzzy?**
+A: Aktifkan mode fuzzy di `SearchOptions` untuk mengizinkan jarak Levenshtein hingga dua edit, yang menangkap kesalahan ketik dan variasi kecil.
+
+**Q: Apakah ada batas ukuran dokumen?**
+A: GroupDocs.Parser dapat menangani EPUB hingga 500 MB; file yang lebih besar harus dibagi atau di‑stream secara manual.
+
+**Q: Apakah saya memerlukan lisensi untuk pengembangan?**
+A: Versi percobaan gratis menyediakan akses penuh ke API dengan watermark penggunaan; lisensi permanen menghapus pembatasan dan memberikan hak komersial.

+
+Mencari pola tertentu dalam file HTML yang sangat besar dapat terasa seperti mencari jarum dalam tumpukan jerami. **cara mencari html** secara efisien adalah pertanyaan umum bagi pengembang Java yang perlu mengekstrak data, memfilter konten, atau mengotomatisasi analisis laporan. Dalam tutorial ini Anda akan menemukan pendekatan praktis berbasis regex yang didukung oleh **GroupDocs.Parser untuk Java**—dari penyiapan hingga pemecahan masalah—sehingga Anda dapat dengan percaya diri menemukan pola teks apa pun di dalam dokumen HTML.
+
+## Jawaban Cepat
+- **Perpustakaan apa yang menangani pencarian regex HTML di Java?** GroupDocs.Parser for Java.
+- **Apakah saya memerlukan lisensi untuk pengembangan?** Uji coba gratis dapat digunakan untuk pengujian; lisensi permanen diperlukan untuk produksi.
+- **Versi Java apa yang diperlukan?** Java 8 atau lebih tinggi (JDK 11 disarankan).
+- **Bisakah saya mencari beberapa file sekaligus?** Ya—bungkus pemanggilan parser dalam loop atau gunakan Java streams.
+- **Kinerja apa yang dapat saya harapkan?** GroupDocs.Parser memproses file HTML 500‑halaman dalam kurang dari 2 detik pada server tipikal.
+
+## Apa itu “cara mencari html” dengan regex?
+**“cara mencari html”** mengacu pada penggunaan regular expression untuk menemukan pola teks di dalam markup HTML. Teknik ini memungkinkan Anda menandai kata, angka, atau tag khusus tanpa harus mem-parsing seluruh pohon DOM. Dengan menerapkan regex langsung pada sumber HTML mentah, pengembang dapat dengan cepat mengekstrak data spesifik, memvalidasi konten, atau menyaring bagian, menjadikannya alternatif ringan dibandingkan parsing DOM penuh.
+
+## Mengapa menggunakan GroupDocs.Parser untuk Java untuk pencarian regex?
+GroupDocs.Parser mendukung **70+** format input dan output—termasuk HTML, DOCX, XLSX, dan PDF—sementara memproses dokumen ratusan halaman tanpa memuat seluruh file ke memori. Kelas `SearchOptions` bawaannya memungkinkan Anda mengaktifkan regular expression, mengontrol sensitivitas huruf, dan membatasi hasil, memberikan pemindaian yang cepat dan efisien memori.
+
+## Prasyarat
+Sebelum memulai, pastikan Anda memiliki:
+
+1. **GroupDocs.Parser untuk Java** (versi terbaru, misalnya 25.5 atau lebih baru).
+2. **Java Development Kit** 8 atau lebih baru yang terpasang dan dikonfigurasi di IDE Anda.
+3. Pemahaman dasar tentang **sintaks regex Java** (misalnya `\d+`, `\bSub\w*`).
+
+## Menyiapkan GroupDocs.Parser untuk Java
+Untuk memulai, tambahkan dependensi Maven ke `pom.xml` Anda:
+
+```xml
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5
+
+```
+
+Untuk unduhan langsung, kunjungi [GroupDocs.Parser for Java releases](https://releases.groupdocs.com/parser/java/) untuk mendapatkan versi terbaru.
+
+**Perolehan Lisensi**
+- **Free Trial** – jelajahi fitur inti tanpa biaya.
+- **Temporary License** – minta kunci uji coba tambahan dari [GroupDocs' website](https://purchase.groupdocs.com/temporary-license/).
+- **Purchase** – dapatkan lisensi penuh untuk penggunaan produksi tak terbatas.
+
+**Inisialisasi**
+Setelah perpustakaan ditambahkan, inisialisasi aplikasi Java Anda untuk menggunakan GroupDocs.Parser:
+
+```java
+import com.groupdocs.parser.Parser;
+
+public class SetupExample {
+ public static void main(String[] args) {
+ String filePath = "path/to/your/document.html";
+ try (Parser parser = new Parser(filePath)) {
+ // Initialization complete, ready to parse and search!
+ } catch (Exception e) {
+ e.printStackTrace();
+ }
+ }
+}
+```
+
+## Cara Mencari HTML Menggunakan GroupDocs.Parser untuk Java?
+Muat file HTML Anda dengan kelas `Parser` dan jalankan pencarian regex dalam hanya dua baris kode. Kelas `Parser` adalah titik masuk yang membaca dan mem-parsing tipe dokumen yang didukung, menyediakan metode untuk ekstraksi teks dan pencarian. Dengan mengonfigurasi `SearchOptions`, Anda memberi tahu parser untuk memperlakukan pola Anda sebagai regular expression, secara opsional mengaktifkan pencocokan sensitif huruf atau pencocokan seluruh kata.
+
+### Implementasi Langkah‑per‑Langkah
+
+### Langkah 1: Tentukan Pola Regular Expression Anda
+Pertama, buat pola regex yang cocok dengan teks yang Anda butuhkan. Dalam contoh ini kami mencari kata yang dimulai dengan **“Sub”** diikuti oleh digit (misalnya `Sub1`, `Sub9`).
+
+```java
+String regexPattern = "Sub[0-9]";
+```
+
+### Langkah 2: Siapkan Opsi Pencarian
+`SearchOptions` adalah objek konfigurasi yang menentukan perilaku pencarian seperti mode regex dan sensitivitas huruf.
+Konfigurasikan objek `SearchOptions` untuk mengaktifkan mode regex, mengatur sensitivitas huruf, dan memutuskan apakah hanya mencocokkan seluruh kata. `SearchOptions` adalah penyimpan konfigurasi yang memberi tahu parser cara melakukan pencarian.
+
+```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options: case-sensitive, whole word, use regex
+SearchOptions options = new SearchOptions(true, false, true);
+```
+
+### Langkah 3: Jalankan Pencarian
+Panggil metode `search` pada instance `Parser`, dengan memberikan jalur file HTML, pola, dan opsi. Metode ini mengembalikan koleksi objek `SearchResult`, masing‑masing berisi teks yang cocok dan lokasinya dalam dokumen.
+
+```java
+import com.groupdocs.parser.data.SearchResult;
+
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.html")) {
+ Iterable results = parser.search(regexPattern, options);
+
+ for (SearchResult result : results) {
+ System.out.println(String.format("At %d: %s", result.getPosition(), result.getText()));
+ }
+} catch (Exception e) {
+ e.printStackTrace();
+}
+```
+
+**Opsi Konfigurasi Utama**
+- **Case Sensitivity** – set `true` untuk pencocokan huruf yang tepat.
+- **Whole Word Search** – `false` termasuk pencocokan parsial.
+- **Use Regular Expressions** – harus `true` untuk mengaktifkan pemrosesan regex.
+
+## Masalah Umum dan Solusinya
+- **Incorrect file path** – pastikan file HTML dapat diakses dari direktori kerja aplikasi Anda.
+- **Invalid regex syntax** – uji pola Anda dengan penguji regex daring sebelum menyematkannya dalam kode.
+- **Memory leaks** – selalu tutup instance `Parser` atau gunakan try‑with‑resources untuk memastikan aliran ditutup.
+
+## Aplikasi Praktis
+Menerapkan pencarian berbasis regex dalam HTML membuka banyak skenario dunia nyata:
+
+1. **Data Extraction** – ambil nomor faktur, ID, atau timestamp dari laporan HTML massal.
+2. **Content Filtering** – secara otomatis menghapus atau menandai bagian yang mengandung kata kunci terlarang.
+3. **Log Analysis** – pindai log berformat HTML untuk pola kesalahan atau metrik kinerja.
+4. **ETL Pipelines** – integrasikan parser ke dalam alur kerja ingest data yang menormalkan konten hasil web‑scraping.
+
+## Pertimbangan Kinerja
+Saat menangani korpora HTML besar, perhatikan tips berikut:
+
+- **Optimize regex patterns** – hindari backtracking berlebihan; gunakan grup atomik atau kuantifier posesif bila memungkinkan.
+- **Streamline memory usage** – bungkus parsing dalam blok try‑with‑resources agar JVM dapat segera mengembalikan buffer.
+- **Parallel processing** – manfaatkan `ForkJoinPool` Java untuk mencari beberapa dokumen secara bersamaan, skala linear pada server multi‑core.
+
+## Pertanyaan yang Sering Diajukan
+
+**Q: Apa itu regular expression?**
+A: Regular expression (regex) adalah bahasa pola singkat untuk mencocokkan urutan karakter dalam string, banyak digunakan untuk validasi, pencarian, dan manipulasi teks.
+
+**Q: Bisakah GroupDocs.Parser menangani file non‑HTML?**
+A: Ya, ia mendukung lebih dari 70 format—termasuk PDF, DOCX, XLSX, dan PPTX—sehingga logika pencarian yang sama dapat diterapkan pada berbagai tipe dokumen.
+
+**Q: Bagaimana saya harus menangani kesalahan parsing?**
+A: Bungkus kode parsing dalam blok try‑catch, tangkap `ParserException` untuk mencatat masalah dan pastikan sumber daya ditutup.
+
+**Q: Regex saya tidak menghasilkan hasil—apa yang salah?**
+A: Periksa kembali pola untuk karakter yang harus di‑escape, verifikasi pengaturan sensitivitas huruf, dan pastikan teks target memang ada dalam sumber HTML.
+
+**Q: Apakah ada batas ukuran untuk file HTML?**
+A: GroupDocs.Parser dapat memproses file hingga 2 GB; untuk file HTML yang sangat besar, pertimbangkan memecahnya atau streaming bagian demi bagian agar tetap dalam batas memori.
+
+## Kesimpulan
+Dengan mengikuti panduan ini Anda kini mengetahui **cara mencari html** dokumen menggunakan mesin regex kuat yang terintegrasi dalam GroupDocs.Parser untuk Java. Anda dapat dengan cepat menemukan pola, mengekstrak data bermakna, dan mengintegrasikan solusi ke dalam aplikasi Java yang lebih besar atau pipeline data.
+
+**Langkah Selanjutnya:** bereksperimen dengan pola yang lebih kompleks, menggabungkan beberapa `SearchOptions`, atau menyematkan parser dalam microservice Spring Boot untuk ekstraksi teks sesuai permintaan.

+# Elaborazione PDF in Java: Ricerca e Evidenziazione con GroupDocs
+
+Ti capita di annegare in un mare di documenti—PDF, file Word o altri formati—e desideri poter trovare facilmente parole o frasi specifiche? **Java PDF processing** lo rende possibile. In questa guida imparerai a cercare testo all'interno dei PDF e a generare frammenti evidenziati usando **GroupDocs.Parser for Java**. Che tu stia costruendo uno strumento di analisi dei documenti o automatizzando la revisione dei contenuti, i passaggi seguenti ti offrono una soluzione chiara e pronta per la produzione.
+
+## Risposte Rapide
+- **Quale libreria gestisce la ricerca di testo PDF in Java?** GroupDocs.Parser for Java.
+- **Ho bisogno di una licenza per lo sviluppo?** Una licenza temporanea funziona per i test; è necessaria una licenza completa per la produzione.
+- **Posso evidenziare più occorrenze contemporaneamente?** Sì—imposta un raggio di evidenziazione e itera sui risultati.
+- **La ricerca è sensibile al maiuscolo/minuscolo?** Per impostazione predefinita non è sensibile al maiuscolo/minuscolo; puoi modificarla tramite `SearchOptions`.
+- **Quali formati sono supportati?** Oltre 50 formati di input e output, inclusi PDF, DOCX, XLSX, PPTX, HTML e immagini.
+
+## Cos'è l'elaborazione PDF in Java?
+`Java PDF processing` è l'insieme di operazioni programmatiche—come estrazione, ricerca e evidenziazione del testo—eseguite sui file PDF usando librerie Java. Con GroupDocs.Parser puoi cercare in qualsiasi documento supportato, recuperare il contesto circostante e applicare evidenziazioni visive, il tutto senza aprire il file in un visualizzatore. Questa capacità ti consente di creare archivi ricercabili veloci e pipeline di revisione automatizzate che scalano a migliaia di pagine per documento.
+
+## Perché usare GroupDocs.Parser per l'elaborazione PDF in Java?
+GroupDocs.Parser supporta **oltre 50 formati di file** e può elaborare **PDF con centinaia di pagine** senza caricare l'intero file in memoria, riducendo l'uso di RAM fino al **70 %** rispetto agli approcci naïf. Il suo motore di ricerca restituisce offset precisi, consentendoti di costruire evidenziazioni UI personalizzate o esportare i risultati verso altri sistemi. La libreria è attivamente mantenuta, compatibile con Java 8+ e offre artefatti Maven e Gradle per una facile integrazione.
+
+## Prerequisiti
+
+Prima di rimboccarci le maniche, assicurati di avere questi elementi pronti:
+
+- **Ambiente di sviluppo Java**: JDK 8+ installato.
+- **Maven o Gradle**: Per la gestione delle dipendenze e la configurazione del progetto.
+- **Libreria GroupDocs.Parser per Java**: Scarica o aggiungi tramite dipendenza.
+- **Un documento di esempio**: PDF o testi di prova su cui effettuare la ricerca.
+- **Conoscenze di base di Java**: Familiarità con classi, metodi e gestione dei file.
+
+Se non hai ancora la libreria, puoi scaricare l'ultima versione da [GroupDocs Downloads](https://releases.groupdocs.com/parser/java/) o aggiungerla via Maven:
+
+```xml
+
+ com.groupdocs
+ groupdocs-parser
+ 21.12
+
+```
+
+## Importa Pacchetti
+
+Per iniziare, importiamo le classi essenziali da GroupDocs.Parser:
+
+`Parser` è la classe principale usata per caricare e interagire con i documenti. `HighlightOptions` configura come il testo corrispondente viene evidenziato. `SearchOptions` definisce il comportamento della ricerca, ad esempio la sensibilità al maiuscolo/minuscolo. `SearchResult` rappresenta una singola corrispondenza trovata nel documento.
+
+```java
+import com.groupdocs.parser.Parser;
+import com.groupdocs.parser.search.HighlightOptions;
+import com.groupdocs.parser.search.SearchOptions;
+import com.groupdocs.parser.search.SearchResult;
+```
+
+Queste importazioni coprono le funzionalità di base per l'analisi dei documenti, la configurazione delle opzioni di evidenziazione e l'esecuzione delle operazioni di ricerca.
+
+## Come funziona il flusso di lavoro di ricerca e evidenziazione?
+
+Carica il tuo PDF, configura un oggetto `HighlightOptions`, esegui `parser.search` e poi itera sulla collezione `SearchResult` per costruire i frammenti evidenziati. L'intero processo avviene in due fasi: prima il parser legge la struttura del documento; poi il motore di ricerca scansiona il flusso di testo applicando le opzioni definite. Questo approccio garantisce alte prestazioni anche su file di grandi dimensioni.
+
+## Guida passo‑passo per cercare testo con evidenziazioni
+
+Procediamo attraverso il processo suddiviso in passaggi chiari e gestibili. Ogni passo ha la sua spiegazione per aiutarti a capire il perché e il come.
+
+### Passo 1: Inizializza il Parser con il tuo documento
+
+**Cosa sta succedendo?**
+Creare un'istanza della classe `Parser` collegata al file del tuo documento ti permette di accedere e analizzarne il contenuto.
+
+`Parser` carica un documento e fornisce metodi per l'estrazione del testo e la ricerca.
+
+```java
+try (Parser parser = new Parser("path/to/your/document.pdf")) {
+ // your code here
+}
+```
+
+**In realtà:**
+L'istruzione `try-with-resources` garantisce che il file venga chiuso correttamente dopo l'elaborazione, evitando perdite di risorse. Sostituisci `"path/to/your/document.pdf"` con il percorso o l'URL preciso del tuo file.
+
+### Passo 2: Configura le opzioni di evidenziazione
+
+**Perché definire le opzioni di evidenziazione?**
+Potresti voler controllare l'aspetto o il comportamento di come i risultati di ricerca vengono evidenziati—ad esempio il numero di caratteri da mostrare intorno alla corrispondenza o il colore (se supportato).
+
+In questo esempio, impostiamo un raggio di evidenziazione di 15 caratteri:
+
+`HighlightOptions` specifica il raggio di contesto e le impostazioni visive per i risultati evidenziati.
+
+```java
+HighlightOptions highlightOptions = new HighlightOptions(15);
+```
+
+Questo avvolge il testo trovato con il contesto circostante—come una lente d'ingrandimento attorno alle parole chiave—rendendo più facile individuare dove si trovano le corrispondenze.
+
+### Passo 3: Esegui la ricerca nel documento
+
+**Come funziona la ricerca?**
+Usando `parser.search`, specifichi la parola chiave o la frase, le opzioni di ricerca e ottieni una collezione iterabile di oggetti `SearchResult`.
+
+`SearchOptions` configura parametri di ricerca come la sensibilità al maiuscolo/minuscolo. `SearchResult` contiene i dettagli di ogni corrispondenza, inclusi il testo corrispondente e la sua posizione.
+
+```java
+Iterable results = parser.search("lorem", new SearchOptions(true, false, false, highlightOptions));
+```
+
+Analisi del costruttore `SearchOptions`:
+
+- `true`: Abilita la ricerca non sensibile al maiuscolo/minuscolo.
+- `false`: Non corrispondere solo a parole intere.
+- `false`: Non cercare pattern regex.
+- `highlightOptions`: Passa la nostra configurazione di evidenziazione.
+
+Questa configurazione ricerca tutte le occorrenze di `"lorem"`, ignorando il caso, e restituisce frammenti evidenziati.
+
+### Passo 4: Gestisci il supporto alla ricerca e i risultati
+
+**Verifica se la ricerca è supportata**
+Alcuni formati potrebbero non supportare la ricerca — verifica sempre:
+
+`parser.isSearchSupported()` restituisce un booleano che indica se il formato del documento caricato consente la ricerca di testo.
+
+```java
+if (results == null) {
+ System.out.println("Search isn't supported in this document format.");
+ return;
+}
+```
+
+**Elabora ogni risultato di ricerca**
+Itera sui risultati per estrarre e visualizzare i frammenti corrispondenti con evidenziazioni:
+
+Gli oggetti `SearchResult` forniscono l'accesso alla frase trovata e al contesto circostante.
+
+```java
+for (SearchResult result : results) {
+ String snippet = String.format("%s%s%s",
+ result.getLeftHighlightItem().getText(),
+ result.getText(),
+ result.getRightHighlightItem().getText());
+ System.out.println(snippet);
+}
+```
+
+## Problemi comuni e soluzioni
+
+| Problema | Motivo | Soluzione |
+|----------|--------|-----------|
+| **Nessun risultato restituito** | Formato del documento non ricercabile | Verifica che `parser.isSearchSupported()` restituisca `true`. |
+| **Il raggio di evidenziazione sembra troppo piccolo** | Il raggio predefinito è di 10 caratteri | Aumenta il raggio in `HighlightOptions` (ad esempio, `new HighlightOptions(20)`). |
+| **Errore di out‑of‑memory su PDF di grandi dimensioni** | L'intero file viene caricato in memoria | Usa `Parser` in modalità streaming o elabora il file a blocchi; GroupDocs.Parser già gestisce lo streaming di file di grandi dimensioni in modo efficiente. |
+| **Sensibilità al maiuscolo/minuscolo non si comporta come previsto** | Flag `caseSensitive` impostato in modo errato | Assicurati che `SearchOptions(true, …)` imposti il booleano corretto per la non sensibilità al maiuscolo/minuscolo. |
+
+## Domande frequenti
+
+**Q: Posso cercare più parole chiave contemporaneamente?**
+A: Non direttamente; itera su ogni parola chiave o costruisci un pattern regex che corrisponda a tutti i termini desiderati.
+
+**Q: Il raggio di evidenziazione influisce su tutti i formati di documento?**
+A: Per la maggior parte dei formati supportati il raggio funziona uniformemente; alcuni formati basati su immagini lo ignorano perché non hanno livelli di testo nativi.
+
+**Q: Posso cambiare i colori di evidenziazione?**
+A: `HighlightOptions` controlla il raggio di contesto; i colori visivi dipendono dal visualizzatore che usi per rendere il PDF, non dal parser stesso.
+
+**Q: La ricerca è sensibile al maiuscolo/minuscolo per impostazione predefinita?**
+A: No. Impostando `caseSensitive` a `false` in `SearchOptions`, la ricerca diventa non sensibile al maiuscolo/minuscolo.
+
+**Q: Questo funziona con immagini scansionate o solo con file basati su testo?**
+A: La ricerca funziona su documenti basati su testo. Per le immagini scansionate è necessario un modulo OCR, fornito da GroupDocs OCR come modulo separato.

Che tu stia costruendo un indicizzatore per una biblioteca digitale o abbia bisogno di individuare frasi specifiche tra migliaia di e‑book, padroneggiare le ricerche con espressioni regolari ti farà risparmiare tempo e migliorerà la precisione. Ti guideremo attraverso l'installazione, le classi chiave e i pattern pratici, coprendo anche **come cercare epub** in modo efficiente.
+
+## Risposte rapide
+- **Quale libreria analizza gli EPUB in Java?** GroupDocs.Parser for Java.
+- **Posso usare le espressioni regolari per la ricerca negli EPUB?** Sì – l'API accetta oggetti Java Pattern.
+- **Come eseguire una ricerca sensibile al maiuscolo/minuscolo?** Imposta `SearchOptions.setIgnoreCase(false)`.
+- **È necessaria una licenza?** Una prova gratuita funziona per i test; una licenza completa rimuove i limiti.
+- **Quale versione di Java è richiesta?** JDK 8 o superiore.
+
+## Cos'è GroupDocs.Parser?
+GroupDocs.Parser è una libreria Java che estrae testo, immagini e metadati da oltre 50 formati di documento, incluso EPUB. Fornisce una classe di alto livello `Parser` che astrae la gestione dei file, permettendoti di concentrarti sulla logica di ricerca anziché sul parsing a basso livello. La libreria trasmette i contenuti in modo efficiente, supporta ambienti con memoria limitata e offre capacità di ricerca integrate che operano direttamente sul testo analizzato.
+
+## Perché usare le espressioni regolari con GroupDocs.Parser per EPUB?
+- **Supporto ampio di formati:** Gestisce oltre 50 formati di input, incluso EPUB, senza convertitori esterni.
+- **Elaborazione efficiente in memoria:** Trasmette i contenuti, consentendo di cercare EPUB con centinaia di pagine senza caricare l'intero file in RAM.
+- **Corrispondenza precisa di pattern:** Le espressioni regolari ti permettono di individuare parole intere, frasi o pattern complessi (ad es., date, ISBN) in una singola chiamata.
+
+## Prerequisiti
+- **Java Development Kit (JDK) 8+** installato e configurato nel tuo IDE o strumento di build.
+- **GroupDocs.Parser for Java** library (disponibile via Maven o download diretto).
+- Familiarità di base con la sintassi Java e i concetti di espressioni regolari.
+
+## Come usare le espressioni regolari per cercare testo nei file EPUB?
+Carica il tuo EPUB con `new Parser("book.epub")` e invoca `search` usando un `Pattern` compilato. Questo approccio a due passaggi isola il caricamento del file dall'esecuzione del pattern, garantendo prestazioni ottimali anche su collezioni di grandi dimensioni.
+
+### Passo 1: Inizializzare il Parser
+La classe `Parser` è il punto di ingresso per caricare e gestire un file EPUB.
+```java
+// ```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/parser/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5
+
+
+```
+```
+
+### Passo 2: Creare un pattern regex
+La classe `Pattern` di Java compila l'espressione regolare. Per esempio, per trovare qualsiasi parola che inizia con “list” dopo un carattere di spazio, usa `\\slist\\w*`.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+// Initialize Parser object with an EPUB file path
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.epub")) {
+ // Your code here
+}
+```
+```
+
+### Passo 3: Configurare le opzioni di ricerca
+`SearchOptions` configura il modo in cui la ricerca opera, ad esempio sensibilità al maiuscolo/minuscolo e corrispondenza fuzzy.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+String epubFilePath = "YOUR_DOCUMENT_DIRECTORY/sample.epub";
+
+try (Parser parser = new Parser(epubFilePath)) {
+ // Further processing steps go here
+}
+```
+```
+
+### Passo 4: Eseguire la ricerca
+`SearchResult` rappresenta una singola corrispondenza, includendo testo, numero di pagina e offset dei caratteri.
+```java
+// ```java
+String regexPattern = \\slist; // Matches any word preceded by whitespace and 'list'
+```
+```
+
+### Passo 5: Elaborare i risultati
+Itera sulla collezione `SearchResult` per registrare le corrispondenze, salvarle in un database o attivare flussi di lavoro a valle come indicizzazione o avvisi.
+```java
+// ```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options for search
+SearchOptions options = new SearchOptions(true /* case match */, false /* whole word */, true /* fuzzy */);
+```
+```
+
+## Come eseguire una ricerca sensibile al maiuscolo/minuscolo in Java?
+Imposta `SearchOptions.setIgnoreCase(false)` per forzare la corrispondenza esatta del caso. Questo è fondamentale quando si cercano identificatori, frammenti di codice o nomi di marchi che devono mantenere la capitalizzazione originale.
+
+## Casi d'uso comuni
+1. **Indicizzazione di biblioteche digitali:** Genera automaticamente indici ricercabili per migliaia di titoli EPUB.
+2. **Curazione dei contenuti:** Individua sezioni tematiche (ad es., “Capitolo 5”) in più libri per la ricerca.
+3. **Data mining:** Estrai entità strutturate come ISBN, date o nomi di autori usando pattern regex su misura.
+4. **Integrazione e‑learning:** Migliora le piattaforme dei corsi con capacità di ricerca full‑text istantanea per PDF e EPUB di materiale didattico.
+
+## Suggerimenti sulle prestazioni
+- **Ottimizza i pattern regex:** Preferisci classi di caratteri semplici rispetto a costrutti con molto back‑tracking per mantenere basso l'uso della CPU.
+- **Dividi gli EPUB grandi:** Elabora i capitoli singolarmente se il file supera i 200 MB per evitare picchi di memoria.
+- **Cache delle query frequenti:** Memorizza i risultati di pattern popolari (ad es., parole chiave comuni) in una mappa leggera in memoria.
+
+## Domande frequenti
+
+**Q: Qual è la differenza tra `search` e `extractText`?**
+A: `search` applica un pattern regex e restituisce solo i frammenti corrispondenti, mentre `extractText` restituisce l'intero contenuto del documento senza filtrare.
+
+**Q: Posso cercare più file EPUB in una singola chiamata?**
+A: Nessuna chiamata API singola elabora un batch, ma è possibile iterare su una lista di file, riutilizzando lo stesso `Pattern` e `SearchOptions` per ciascun file.
+
+**Q: Come funziona la ricerca fuzzy?**
+A: Abilita la modalità fuzzy in `SearchOptions` per consentire una distanza di Levenshtein fino a due modifiche, che cattura errori di battitura e variazioni minori.
+
+**Q: Esiste un limite alla dimensione del documento?**
+A: GroupDocs.Parser può gestire EPUB fino a 500 MB; i file più grandi dovrebbero essere divisi o trasmessi manualmente.
+
+**Q: È necessaria una licenza per lo sviluppo?**
+A: Una prova gratuita fornisce pieno accesso all'API con un watermark di utilizzo; una licenza permanente rimuove le restrizioni e concede diritti commerciali.

+- **Quale versione di Java è richiesta?** Java 8 o superiore (JDK 11 raccomandato).
+- **Posso cercare più file contemporaneamente?** Sì—avvolgi la chiamata al parser in un ciclo o usa gli stream di Java.
+- **Quale prestazione posso aspettarmi?** GroupDocs.Parser elabora file HTML di 500 pagine in meno di 2 secondi su un server tipico.
+
+## Cos’è “come cercare html” con regex?
+**“Come cercare html”** si riferisce all'uso delle espressioni regolari per individuare schemi di testo all'interno del markup HTML. Questa tecnica consente di individuare parole, numeri o tag personalizzati senza analizzare l'intero albero DOM. Applicando regex direttamente al sorgente HTML grezzo, gli sviluppatori possono estrarre rapidamente dati specifici, convalidare contenuti o filtrare sezioni, rendendola un'alternativa leggera al parsing completo del DOM.
+
+## Perché usare GroupDocs.Parser per Java per ricerche regex?
+GroupDocs.Parser supporta **70+** formati di input e output—including HTML, DOCX, XLSX e PDF—mentre elabora documenti di centinaia di pagine senza caricare l'intero file in memoria. La sua classe nativa `SearchOptions` consente di abilitare le espressioni regolari, controllare la sensibilità al maiuscolo/minuscolo e limitare i risultati, offrendo scansioni rapide ed efficienti in termini di memoria.
+
+## Prerequisiti
+Prima di immergerti, assicurati di avere:
+
+1. **GroupDocs.Parser for Java** (ultima versione, ad es., 25.5 o più recente).
+2. **Java Development Kit** 8 o successivo installato e configurato nel tuo IDE.
+3. Familiarità di base con la **sintassi regex di Java** (ad es., `\d+`, `\bSub\w*`).
+
+## Configurazione di GroupDocs.Parser per Java
+Per iniziare, aggiungi la dipendenza Maven al tuo `pom.xml`:
+
+```xml
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5
+
+```
+
+Per scaricare direttamente, visita [GroupDocs.Parser for Java releases](https://releases.groupdocs.com/parser/java/) per ottenere l'ultima versione.
+
+**Acquisizione licenza**
+- **Free Trial** – esplora le funzionalità principali senza costi.
+- **Temporary License** – richiedi una chiave di test estesa dal [sito di GroupDocs](https://purchase.groupdocs.com/temporary-license/).
+- **Purchase** – ottieni una licenza completa per uso illimitato in produzione.
+
+**Inizializzazione**
+Una volta aggiunta la libreria, inizializza la tua applicazione Java per usare GroupDocs.Parser:
+
+```java
+import com.groupdocs.parser.Parser;
+
+public class SetupExample {
+ public static void main(String[] args) {
+ String filePath = "path/to/your/document.html";
+ try (Parser parser = new Parser(filePath)) {
+ // Initialization complete, ready to parse and search!
+ } catch (Exception e) {
+ e.printStackTrace();
+ }
+ }
+}
+```
+
+## Come cercare HTML usando GroupDocs.Parser per Java?
+Carica il tuo file HTML con la classe `Parser` ed esegui una ricerca regex in sole due righe di codice. La classe `Parser` è il punto di ingresso che legge e analizza i tipi di documento supportati, esponendo metodi per l'estrazione di testo e la ricerca. Configurando `SearchOptions`, indichi al parser di trattare il tuo modello come un'espressione regolare, abilitando facoltativamente la corrispondenza sensibile al maiuscolo/minuscolo o a parole intere.
+
+### Implementazione passo‑passo
+
+### Passo 1: Definisci il tuo modello di espressione regolare
+Per prima cosa, crea il modello regex che corrisponde al testo necessario. In questo esempio cerchiamo parole che iniziano con **“Sub”** seguite da una cifra (ad es., `Sub1`, `Sub9`).
+
+```java
+String regexPattern = "Sub[0-9]";
+```
+
+### Passo 2: Configura le opzioni di ricerca
+`SearchOptions` è un oggetto di configurazione che specifica il comportamento della ricerca, come la modalità regex e la sensibilità al caso.
+Configura l'oggetto `SearchOptions` per attivare la modalità regex, impostare la sensibilità al caso e decidere se corrispondere solo a parole intere. `SearchOptions` è un contenitore di configurazione che indica al parser come eseguire la ricerca.
+
+```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options: case-sensitive, whole word, use regex
+SearchOptions options = new SearchOptions(true, false, true);
+```
+
+### Passo 3: Esegui la ricerca
+Invoca il metodo `search` su un'istanza di `Parser`, passando il percorso del file HTML, il modello e le opzioni. Il metodo restituisce una collezione di oggetti `SearchResult`, ognuno contenente il testo corrispondente e la sua posizione nel documento.
+
+```java
+import com.groupdocs.parser.data.SearchResult;
+
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.html")) {
+ Iterable results = parser.search(regexPattern, options);
+
+ for (SearchResult result : results) {
+ System.out.println(String.format("At %d: %s", result.getPosition(), result.getText()));
+ }
+} catch (Exception e) {
+ e.printStackTrace();
+}
+```
+
+**Opzioni di configurazione chiave**
+- **Case Sensitivity** – imposta `true` per corrispondenze esatte al caso.
+- **Whole Word Search** – `false` include corrispondenze parziali.
+- **Use Regular Expressions** – deve essere `true` per abilitare l'elaborazione regex.
+
+## Problemi comuni e soluzioni
+- **Incorrect file path** – verifica che il file HTML sia raggiungibile dalla directory di lavoro della tua applicazione.
+- **Invalid regex syntax** – testa il tuo modello con un tester regex online prima di inserirlo nel codice.
+- **Memory leaks** – chiudi sempre l'istanza `Parser` o usa try‑with‑resources per garantire il rilascio degli stream.
+
+## Applicazioni pratiche
+Impiego di ricerche guidate da regex in HTML apre le porte a molti scenari reali:
+
+1. **Data Extraction** – estrai numeri di fattura, ID o timestamp da report HTML di grandi dimensioni.
+2. **Content Filtering** – rimuovi o segnala automaticamente sezioni contenenti parole chiave proibite.
+3. **Log Analysis** – analizza i log formattati in HTML per schemi di errore o metriche di prestazioni.
+4. **ETL Pipelines** – integra il parser nei flussi di lavoro di ingestione dati che normalizzano contenuti web‑scraped.
+
+## Considerazioni sulle prestazioni
+Quando gestisci grandi corpora HTML, tieni presenti questi consigli:
+
+- **Optimize regex patterns** – evita backtracking eccessivo; usa gruppi atomici o quantificatori possessivi quando possibile.
+- **Streamline memory usage** – avvolgi il parsing in un blocco try‑with‑resources per consentire alla JVM di recuperare rapidamente i buffer.
+- **Parallel processing** – sfrutta il `ForkJoinPool` di Java per cercare più documenti contemporaneamente, scalando linearmente su server multi‑core.
+
+## Domande frequenti
+
+**Q: Cos'è un'espressione regolare?**
+A: Un'espressione regolare (regex) è un linguaggio conciso basato su modelli per abbinare sequenze di caratteri all'interno di stringhe, ampiamente usato per la convalida, la ricerca e la manipolazione del testo.
+
+**Q: GroupDocs.Parser può gestire file non‑HTML?**
+A: Sì, supporta oltre 70 formati—including PDF, DOCX, XLSX e PPTX—quindi la stessa logica di ricerca funziona su diversi tipi di documento.
+
+**Q: Come devo gestire gli errori di parsing?**
+A: Avvolgi il codice di parsing in un blocco try‑catch, catturando `ParserException` per registrare il problema e garantire la chiusura delle risorse.
+
+**Q: La mia regex non restituisce risultati—cosa c'è di sbagliato?**
+A: Controlla nuovamente il modello per caratteri di escape, verifica le impostazioni di sensibilità al caso e conferma che il testo target esista effettivamente nel sorgente HTML.
+
+**Q: Esiste un limite di dimensione per i file HTML?**
+A: GroupDocs.Parser può elaborare file fino a 2 GB; per file HTML estremamente grandi, considera di suddividerli o di streammare sezioni per rimanere entro i limiti di memoria.
+
+## Conclusione
+Seguendo questa guida ora sai **come cercare html** nei documenti usando un potente motore regex integrato in GroupDocs.Parser per Java. Puoi individuare rapidamente i pattern, estrarre dati significativi e integrare la soluzione in applicazioni Java più grandi o pipeline di dati.
+
+**Prossimi passi:** sperimenta con pattern più complessi, combina più `SearchOptions` o incorpora il parser in un microservizio Spring Boot per l'estrazione di testo on‑demand.

+# Java PDF 処理: 検索とハイライト with GroupDocs
+
+大量のドキュメント—PDF、Word ファイル、その他の形式—に埋もれて、特定の単語やフレーズを簡単に見つけられたらいいなと思ったことはありませんか？**Java PDF processing** がそれを可能にします。このガイドでは **GroupDocs.Parser for Java** を使用して PDF 内のテキストを検索し、ハイライトされたスニペットを生成する方法を学びます。ドキュメント分析ツールを構築する場合でも、コンテンツレビューを自動化する場合でも、以下の手順は明確で本番環境向けのソリューションを提供します。
+
+## クイック回答
+- **Java で PDF テキスト検索を処理するライブラリはどれですか？** GroupDocs.Parser for Java。
+- **開発にライセンスは必要ですか？** テスト用の一時ライセンスで動作しますが、本番環境ではフルライセンスが必要です。
+- **複数の出現箇所を同時にハイライトできますか？** はい—ハイライト半径を設定し、結果を反復処理します。
+- **検索は大文字と小文字を区別しますか？** デフォルトでは大文字小文字を区別しません；`SearchOptions` で切り替え可能です。
+- **サポートされているフォーマットは何ですか？** PDF、DOCX、XLSX、PPTX、HTML、画像など、50 以上の入力・出力フォーマットに対応しています。
+
+## Java PDF 処理とは何ですか？
+
+`Java PDF processing` は、Java ライブラリを使用して PDF ファイル上で実行される、抽出、検索、ハイライトなどのプログラム的操作の集合です。GroupDocs.Parser を使えば、サポートされている任意のドキュメントを検索し、周囲のコンテキストを取得し、ビジュアルハイライトを適用できます。ビューアでファイルを開く必要はありません。この機能により、数千ページに及ぶドキュメントでも高速で検索可能なアーカイブや自動レビュー パイプラインを構築できます。
+
+## Java PDF 処理に GroupDocs.Parser を使用する理由
+
+GroupDocs.Parser は **50+ ファイル形式** をサポートし、**数百ページの PDF** をメモリ全体にロードせずに処理でき、ナイーブなアプローチと比較して RAM 使用量を最大 **70 %** 削減します。検索エンジンは正確なオフセットを返すため、カスタム UI ハイライトの構築や結果の他システムへのエクスポートが容易です。ライブラリは積極的にメンテナンスされ、Java 8+ に対応し、Maven と Gradle の両方のアーティファクトを提供して簡単に統合できます。
+
+## 前提条件
+
+作業を始める前に、以下の必須項目を用意してください：
+
+- **Java 開発環境**: JDK 8+ がインストールされていること。
+- **Maven または Gradle**: 依存関係管理とプロジェクト設定のため。
+- **GroupDocs.Parser for Java ライブラリ**: ダウンロードまたは依存関係として追加。
+- **サンプルドキュメント**: テスト用の PDF またはテキスト。
+- **基本的な Java 知識**: クラス、メソッド、ファイル操作に慣れていること。
+
+ライブラリがまだない場合は、[GroupDocs Downloads](https://releases.groupdocs.com/parser/java/) から最新バージョンを取得するか、Maven で追加してください。
+
+```xml
+
+ com.groupdocs
+ groupdocs-parser
+ 21.12
+
+```
+
+## パッケージのインポート
+
+まず、GroupDocs.Parser から必要なクラスをインポートします。
+
+`Parser` はドキュメントのロードと操作に使用される主要クラスです。`HighlightOptions` は一致したテキストのハイライト方法を設定します。`SearchOptions` は大文字小文字の区別など検索動作を定義します。`SearchResult` はドキュメント内で見つかった個々の一致を表します。
+
+```java
+import com.groupdocs.parser.Parser;
+import com.groupdocs.parser.search.HighlightOptions;
+import com.groupdocs.parser.search.SearchOptions;
+import com.groupdocs.parser.search.SearchResult;
+```
+
+これらのインポートは、ドキュメントの解析、ハイライトオプションの設定、検索操作のコア機能をカバーします。
+
+## 検索とハイライトのワークフローはどのように機能しますか？
+
+PDF をロードし、`HighlightOptions` オブジェクトを設定し、`parser.search` を実行し、`SearchResult` コレクションを反復処理してハイライトされたスニペットを作成します。プロセスは 2 段階で実行されます：最初にパーサーがドキュメント構造を読み取り、次に検索エンジンがテキストストリームを走査し、定義したオプションを適用します。このアプローチにより、大容量ファイルでも高いパフォーマンスが保証されます。
+
+## ハイライト付きテキスト検索のステップバイステップガイド
+
+プロセスを管理しやすく明確なステップに分割して説明します。各ステップには「なぜ」や「どうやって」の理解を助ける解説が付いています。
+
+### ステップ 1: ドキュメントで Parser を初期化する
+
+**What’s happening here?**
+`Parser` クラスのインスタンスをドキュメントファイルに結び付けることで、コンテンツへのアクセスと解析が可能になります。
+
+`Parser` はドキュメントをロードし、テキスト抽出や検索のメソッドを提供します。
+
+```java
+try (Parser parser = new Parser("path/to/your/document.pdf")) {
+ // your code here
+}
+```
+
+**In actuality:**
+`try-with-resources` 文により、処理後にファイルが適切に閉じられ、リソースリークが防止されます。`"path/to/your/document.pdf"` を実際のファイルパスまたは URL に置き換えてください。
+
+### ステップ 2: ハイライトオプションを設定する
+
+**Why define highlight options?**
+検索ヒットのハイライト表示方法（マッチ周辺の文字数や色など）を制御したい場合があります。
+
+この例ではハイライト半径を 15 文字に設定しています：
+
+`HighlightOptions` はハイライト検索ヒットのコンテキスト半径とビジュアル設定を指定します。
+
+```java
+HighlightOptions highlightOptions = new HighlightOptions(15);
+```
+
+これにより、見つかったテキストが周囲のコンテキストで囲まれ、キーワードがどこに出現しているかが一目で分かります。
+
+### ステップ 3: ドキュメント内で検索を実行する
+
+**How does the search work?**
+`parser.search` を使用してキーワードまたはフレーズ、検索オプションを指定し、`SearchResult` オブジェクトの反復可能コレクションを取得します。
+
+`SearchOptions` は大文字小文字の区別など検索パラメータを設定します。`SearchResult` は各一致の詳細（一致テキストと位置）を保持します。
+
+```java
+Iterable results = parser.search("lorem", new SearchOptions(true, false, false, highlightOptions));
+```
+
+`SearchOptions` コンストラクタの内訳：
+
+- `true`: 大文字小文字を区別しない検索を有効化。
+- `false`: 完全一致（単語単位）のみを対象にしない。
+- `false`: 正規表現パターン検索を行わない。
+- `highlightOptions`: ハイライト設定を渡す。
+
+この設定により、`"lorem"` のすべての出現箇所を大文字小文字を無視して検索し、ハイライトされたスニペットが生成されます。
+
+### ステップ 4: 検索サポートと結果の処理
+
+**Check if search is supported**
+一部のフォーマットは検索をサポートしない可能性があるため、常に確認してください：
+
+`parser.isSearchSupported()` は、ロードされたドキュメント形式がテキスト検索を許可しているかどうかを示すブール値を返します。
+
+```java
+if (results == null) {
+ System.out.println("Search isn't supported in this document format.");
+ return;
+}
+```
+
+**Process each search hit**
+結果をループして、ハイライト付きのマッチングスニペットを抽出・表示します：
+
+`SearchResult` オブジェクトから一致したフレーズとその周囲コンテキストにアクセスできます。
+
+```java
+for (SearchResult result : results) {
+ String snippet = String.format("%s%s%s",
+ result.getLeftHighlightItem().getText(),
+ result.getText(),
+ result.getRightHighlightItem().getText());
+ System.out.println(snippet);
+}
+```
+
+## 一般的な問題と解決策
+
+| Issue | Reason | Fix |
+|-------|--------|-----|
+| **結果が返されない** | ドキュメント形式が検索非対応 | `parser.isSearchSupported()` が `true` を返すことを確認してください。 |
+| **ハイライト半径が小さすぎる** | デフォルト半径は 10 文字 | `HighlightOptions` の半径を増やす（例: `new HighlightOptions(20)`）。 |
+| **大容量 PDF で Out‑of‑memory エラー** | ファイル全体がメモリにロードされる | ストリーミングモードで `Parser` を使用するか、ファイルをチャンクで処理してください。GroupDocs.Parser は大きなファイルを効率的にストリーミングします。 |
+| **大文字小文字の挙動が期待通りでない** | `caseSensitive` フラグが誤設定 | `SearchOptions(true, …)` が大文字小文字非区別の正しいブール値を設定していることを確認してください。 |
+
+## よくある質問
+
+**Q: 複数のキーワードを同時に検索できますか？**
+A: 直接はできません。各キーワードを順にイテレートするか、すべての対象語にマッチする正規表現パターンを構築してください。
+
+**Q: ハイライト半径はすべてのドキュメント形式に影響しますか？**
+A: 大半のサポート形式で半径は均一に機能しますが、テキストレイヤーを持たない画像ベースの形式では無視されます。
+
+**Q: ハイライトの色を変更できますか？**
+A: `HighlightOptions` はコンテキスト半径を制御します。色は PDF をレンダリングするビューアに依存し、パーサー自体では設定できません。
+
+**Q: デフォルトで検索は大文字小文字を区別しますか？**
+A: いいえ。`SearchOptions` で `caseSensitive` を `false` に設定すると、検索は大文字小文字を区別しなくなります。
+
+**Q: スキャンした画像でも動作しますか、テキストベースのファイルだけですか？**
+A: 検索はテキストベースのドキュメントでのみ機能します。スキャン画像の場合は OCR 機能が必要で、これは別モジュールの GroupDocs OCR が提供します。

+
+## クイック回答
+- **Java で EPUB を解析するライブラリは何ですか？** GroupDocs.Parser for Java.
+- **EPUB 検索に正規表現を使用できますか？** はい – API は Java Pattern オブジェクトを受け付けます。
+- **大文字小文字を区別した検索を実行するには？** `SearchOptions.setIgnoreCase(false)` を設定します。
+- **ライセンスは必要ですか？** 無料トライアルでテスト可能です。フルライセンスを取得すれば制限が解除されます。
+- **必要な Java バージョンはどれですか？** JDK 8 以上。
+
+## GroupDocs.Parser とは何ですか？
+GroupDocs.Parser は、EPUB を含む 50 以上のドキュメント形式からテキスト、画像、メタデータを抽出する Java ライブラリです。高レベルの `Parser` クラスがファイル処理を抽象化し、低レベルのパースに煩わされることなく検索ロジックに集中できます。ライブラリはコンテンツを効率的にストリーミングし、メモリ制約のある環境でも動作し、解析済みテキストに直接作用する組み込み検索機能を提供します。
+
+## EPUB に対して GroupDocs.Parser と正規表現を使用する理由
+- **Broad format support:** 50 以上の入力形式に対応し、外部コンバータなしで EPUB を処理できます。
+- **Memory‑efficient processing:** コンテンツをストリーミングし、数百ページに及ぶ EPUB でも全体を RAM にロードせずに検索できます。
+- **Precise pattern matching:** 正規表現を使用すれば、単語、フレーズ、日付や ISBN などの複雑なパターンを単一呼び出しで特定できます。
+
+## 前提条件
+- **Java Development Kit (JDK) 8+** がインストールされ、IDE またはビルドツールで設定されていること。
+- **GroupDocs.Parser for Java** ライブラリ（Maven もしくは直接ダウンロードで入手可能）。
+- Java の構文と正規表現の概念に基本的に慣れていること。
+
+## EPUB ファイル内のテキスト検索に正規表現を使用する方法？
+
+`new Parser("book.epub")` で EPUB をロードし、コンパイル済み `Pattern` を使って `search` を呼び出します。この 2 段階アプローチにより、ファイルのロードとパターン実行を分離し、大規模コレクションでも最適なパフォーマンスを実現します。
+
+### 手順 1: パーサーの初期化
+`Parser` クラスは EPUB ファイルのロードと処理のエントリーポイントです。
+```java
+// ```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/parser/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5
+
+
+```
+```
+
+### 手順 2: 正規表現パターンの構築
+Java の `Pattern` クラスは正規表現をコンパイルします。たとえば、空白文字の後に「list」で始まる単語を検索するには `\\slist\\w*` を使用します。
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+// Initialize Parser object with an EPUB file path
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.epub")) {
+ // Your code here
+}
+```
+```
+
+### 手順 3: 検索オプションの設定
+`SearchOptions` は検索の動作（大文字小文字の区別やファジーマッチングなど）を構成します。
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+String epubFilePath = "YOUR_DOCUMENT_DIRECTORY/sample.epub";
+
+try (Parser parser = new Parser(epubFilePath)) {
+ // Further processing steps go here
+}
+```
+```
+
+### 手順 4: 検索の実行
+`SearchResult` は単一の一致を表し、テキスト、ページ番号、文字オフセットを含みます。
+```java
+// ```java
+String regexPattern = \\slist; // Matches any word preceded by whitespace and 'list'
+```
+```
+
+### 手順 5: 結果の処理
+`SearchResult` コレクションを反復処理して一致をログに記録したり、データベースに保存したり、インデックス作成やアラートなどの下流ワークフローをトリガーします。
+```java
+// ```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options for search
+SearchOptions options = new SearchOptions(true /* case match */, false /* whole word */, true /* fuzzy */);
+```
+```
+
+## Java で大文字小文字を区別した検索を実行する方法
+`SearchOptions.setIgnoreCase(false)` を設定して、正確な大文字小文字の一致を強制します。識別子、コードスニペット、ブランド名など、元のケースを保持する必要がある検索で重要です。
+
+## 主なユースケース
+1. **Digital Library Indexing:** 数千の EPUB タイトルに対して検索可能なインデックスを自動生成します。
+2. **Content Curation:** 複数の書籍からテーマ別セクション（例: “Chapter 5”）を検索し、研究に活用します。
+3. **Data Mining:** カスタマイズした正規表現パターンを使用して、ISBN、日付、著者名などの構造化エンティティを抽出します。
+4. **E‑Learning Integration:** コースプラットフォームに即時全文検索機能を追加し、PDF や EPUB の教材を高速に検索できるようにします。
+
+## パフォーマンスのヒント
+- **Optimize regex patterns:** バックトラッキングが重い構造よりもシンプルな文字クラスを優先し、CPU 使用率を低く抑えます。
+- **Chunk large EPUBs:** ファイルが 200 MB を超える場合は章単位で処理し、メモリスパイクを回避します。
+- **Cache frequent queries:** 人気のパターン（例: 共通キーワード）の結果を軽量なインメモリマップに保存します。
+
+## よくある質問
+
+**Q: `search` と `extractText` の違いは何ですか？**
+A: `search` は正規表現パターンを適用し一致したフラグメントだけを返すのに対し、`extractText` はフィルタリングせずにドキュメント全体の内容を返します。
+
+**Q: 複数の EPUB ファイルを一度に検索できますか？**
+A: 単一の API 呼び出しでバッチ処理はできませんが、ファイルリストをループし、同じ `Pattern` と `SearchOptions` を各ファイルに再利用できます。
+
+**Q: ファジー検索はどのように機能しますか？**
+A: `SearchOptions` でファジーモードを有効にすると、最大 2 文字のレーベンシュタイン距離を許容し、スペルミスや軽微な変形をキャッチします。
+
+**Q: ドキュメントサイズに制限はありますか？**
+A: GroupDocs.Parser は最大 500 MB の EPUB を処理できます。より大きなファイルは分割するか手動でストリーミングしてください。
+
+**Q: 開発用にライセンスは必要ですか？**
+A: 無料トライアルでフル API アクセスと使用時の透かしが提供されます。永続ライセンスを取得すれば制限が解除され、商用利用が可能になります。

+ }
+ }
+}
+```
+
+## GroupDocs.Parser for Java を使用した HTML の検索方法？
+HTML ファイルを `Parser` クラスで読み込み、わずか 2 行のコードで正規表現検索を実行します。`Parser` クラスは、サポートされているドキュメントタイプを読み取り解析するエントリーポイントで、テキスト抽出や検索のメソッドを提供します。`SearchOptions` を設定することで、パターンを正規表現として扱うようパーサーに指示でき、大小文字の区別や完全一致検索をオプションで有効にできます。
+
+### ステップバイステップ実装
+
+### ステップ 1: 正規表現パターンを定義する
+まず、必要なテキストにマッチする正規表現パターンを作成します。この例では、**“Sub”** で始まり数字が続く単語（例: `Sub1`, `Sub9`）を検索します。
+
+```java
+String regexPattern = "Sub[0-9]";
+```
+
+### ステップ 2: SearchOptions の設定
+`SearchOptions` は、正規表現モードや大小文字の感度など、検索動作を指定する構成オブジェクトです。
+`SearchOptions` オブジェクトを設定して正規表現モードを有効にし、大小文字の感度を設定し、完全一致のみを検索するかどうかを決定します。`SearchOptions` は、パーサーに検索方法を指示する構成ホルダーです。
+
+```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options: case-sensitive, whole word, use regex
+SearchOptions options = new SearchOptions(true, false, true);
+```
+
+### ステップ 3: 検索を実行する
+`Parser` インスタンスの `search` メソッドを呼び出し、HTML ファイルのパス、パターン、オプションを渡します。このメソッドは `SearchResult` オブジェクトのコレクションを返し、各オブジェクトは一致したテキストと文書内の位置を含みます。
+
+```java
+import com.groupdocs.parser.data.SearchResult;
+
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.html")) {
+ Iterable results = parser.search(regexPattern, options);
+
+ for (SearchResult result : results) {
+ System.out.println(String.format("At %d: %s", result.getPosition(), result.getText()));
+ }
+} catch (Exception e) {
+ e.printStackTrace();
+}
+```
+
+**Key Configuration Options**
+- **Case Sensitivity** – 完全な大文字小文字の一致を求める場合は `true` を設定します。
+- **Whole Word Search** – `false` にすると部分一致も含まれます。
+- **Use Regular Expressions** – 正規表現処理を有効にするには `true` にする必要があります。
+
+## よくある問題と解決策
+- **Incorrect file path** – HTML ファイルがアプリケーションの作業ディレクトリからアクセス可能か確認してください。
+- **Invalid regex syntax** – コードに組み込む前に、オンライン正規表現テスターでパターンをテストしてください。
+- **Memory leaks** – 常に `Parser` インスタンスを閉じるか、try‑with‑resources を使用してストリームが解放されるようにしてください。
+
+## 実用的な活用例
+HTML で正規表現駆動検索を活用することで、さまざまな実務シナリオが可能になります：
+
+1. **Data Extraction** – 大量の HTML レポートから請求書番号、ID、タイムスタンプなどを抽出します。
+2. **Content Filtering** – 禁止キーワードを含むセクションを自動的に削除またはフラグ付けします。
+3. **Log Analysis** – HTML 形式のログをスキャンし、エラーパターンやパフォーマンス指標を検出します。
+4. **ETL Pipelines** – パーサーをデータ取り込みワークフローに統合し、ウェブスクレイピングされたコンテンツを正規化します。
+
+## パフォーマンス上の考慮点
+大規模な HTML コーパスを扱う際は、以下のポイントに留意してください：
+
+- **Optimize regex patterns** – 過度なバックトラッキングを避け、可能な場合はアトミックグループやポゼッシブ量指定子を使用してください。
+- **Streamline memory usage** – パース処理を try‑with‑resources ブロックでラップし、JVM がバッファを速やかに回収できるようにします。
+- **Parallel processing** – Java の `ForkJoinPool` を活用して複数のドキュメントを同時に検索し、マルチコアサーバーで線形にスケールさせます。
+
+## よくある質問
+
+**Q: 正規表現とは何ですか？**
+A: 正規表現（regex）は、文字列内の文字シーケンスにマッチするための簡潔なパターンベースの言語で、検証、検索、テキスト操作に広く使用されます。
+
+**Q: GroupDocs.Parser は非 HTML ファイルを処理できますか？**
+A: はい、PDF、DOCX、XLSX、PPTX など 70 以上のフォーマットをサポートしているため、同じ検索ロジックがさまざまなドキュメントタイプで機能します。
+
+**Q: パースエラーはどのように処理すべきですか？**
+A: パースコードを try‑catch ブロックで囲み、`ParserException` を捕捉して問題をログに記録し、リソースが確実に閉じられるようにします。
+
+**Q: 正規表現が結果を返さないのですが、何が問題ですか？**
+A: エスケープ文字を含むパターンを再確認し、大小文字感度設定を確認し、対象テキストが HTML ソースに実際に存在するかを確かめてください。
+
+**Q: HTML ファイルのサイズ制限はありますか？**
+A: GroupDocs.Parser は最大 2 GB のファイルを処理できます。極端に大きな HTML ファイルの場合は、ファイルを分割するか、セクションをストリーミングしてメモリ制約内に収めることを検討してください。

+GroupDocs.Parser는 **50개 이상의 파일 형식**을 지원하며 전체 파일을 메모리에 로드하지 않고 **수백 페이지 PDF**를 처리할 수 있어, 단순한 방법에 비해 RAM 사용량을 최대 **70 %**까지 줄여줍니다. 검색 엔진은 정확한 오프셋을 반환하므로 맞춤 UI 강조 표시를 만들거나 결과를 다른 시스템으로 내보낼 수 있습니다. 이 라이브러리는 활발히 유지 관리되고 있으며, Java 8+와 호환되고 Maven 및 Gradle 아티팩트를 모두 제공하여 손쉽게 통합할 수 있습니다.
+
+## 사전 요구 사항
+
+본격적으로 시작하기 전에, 다음 필수 항목들을 준비했는지 확인하세요:
+
+- **Java 개발 환경**: JDK 8+가 설치되어 있어야 합니다.
+- **Maven 또는 Gradle**: 의존성 관리 및 프로젝트 설정용.
+- **GroupDocs.Parser for Java 라이브러리**: 다운로드하거나 의존성으로 추가합니다.
+- **샘플 문서**: 검색할 테스트용 PDF 또는 텍스트.
+- **기본 Java 지식**: 클래스, 메서드 및 파일 처리에 익숙함.
+
+아직 라이브러리가 없으시다면, 최신 버전을 [GroupDocs Downloads](https://releases.groupdocs.com/parser/java/)에서 다운로드하거나 Maven을 통해 추가할 수 있습니다:
+
+```xml
+
+ com.groupdocs
+ groupdocs-parser
+ 21.12
+
+```
+
+## 패키지 가져오기
+
+시작하기 위해 GroupDocs.Parser에서 필수 클래스를 가져오겠습니다:
+
+`Parser`는 문서를 로드하고 상호 작용하는 데 사용되는 주요 클래스입니다. `HighlightOptions`는 일치하는 텍스트가 어떻게 강조 표시되는지를 구성합니다. `SearchOptions`는 대소문자 구분과 같은 검색 동작을 정의합니다. `SearchResult`는 문서에서 발견된 개별 매치를 나타냅니다.
+
+```java
+import com.groupdocs.parser.Parser;
+import com.groupdocs.parser.search.HighlightOptions;
+import com.groupdocs.parser.search.SearchOptions;
+import com.groupdocs.parser.search.SearchResult;
+```
+
+이러한 import는 문서 파싱, 강조 옵션 설정 및 검색 작업을 수행하기 위한 핵심 기능을 포함합니다.
+
+## 검색 및 강조 워크플로우는 어떻게 작동하나요?
+
+PDF를 로드하고 `HighlightOptions` 객체를 구성한 뒤 `parser.search`를 실행하고, `SearchResult` 컬렉션을 반복하여 강조된 스니펫을 만듭니다. 전체 과정은 두 단계로 진행됩니다: 첫 번째로 파서는 문서 구조를 읽고, 두 번째로 검색 엔진은 정의한 옵션을 적용하면서 텍스트 스트림을 스캔합니다. 이 접근 방식은 대용량 파일에서도 높은 성능을 보장합니다.
+
+## 강조와 함께 텍스트 검색 단계별 가이드
+
+프로세스를 관리하기 쉬운 단계로 나누어 살펴보겠습니다. 각 단계마다 왜와 어떻게에 대한 설명이 포함되어 있습니다.
+
+### 단계 1: 문서로 Parser 초기화
+
+**여기서 무슨 일이 일어나나요?**
+`Parser` 클래스의 인스턴스를 문서 파일에 연결하여 생성하면 해당 콘텐츠에 접근하고 분석할 수 있습니다.
+
+`Parser`는 문서를 로드하고 텍스트 추출 및 검색 메서드를 제공합니다.
+
+```java
+try (Parser parser = new Parser("path/to/your/document.pdf")) {
+ // your code here
+}
+```
+
+**실제로:**
+`try-with-resources` 구문은 처리 후 파일이 올바르게 닫히도록 보장하여 리소스 누수를 방지합니다. `"path/to/your/document.pdf"`를 실제 파일 경로나 URL로 교체하세요.
+
+### 단계 2: 강조 옵션 설정
+
+**왜 강조 옵션을 정의하나요?**
+검색 결과가 강조 표시되는 방식의 외관이나 동작을 제어하고 싶을 수 있습니다—예를 들어 매치 주변에 표시할 문자 수나 색상(지원되는 경우) 등.
+
+이 예시에서는 강조 반경을 15자로 설정합니다:
+
+`HighlightOptions`는 강조된 검색 결과에 대한 컨텍스트 반경 및 시각적 설정을 지정합니다.
+
+```java
+HighlightOptions highlightOptions = new HighlightOptions(15);
+```
+
+이렇게 하면 찾은 텍스트가 주변 컨텍스트와 함께 감싸져, 키워드 주변을 확대경으로 보는 것처럼 매치가 발생한 위치를 쉽게 파악할 수 있습니다.
+
+### 단계 3: 문서에서 검색 수행
+
+**검색은 어떻게 작동하나요?**
+`parser.search`를 사용하여 키워드 또는 구문과 검색 옵션을 지정하면 `SearchResult` 객체의 반복 가능한 컬렉션을 얻을 수 있습니다.
+
+`SearchOptions`는 대소문자 구분과 같은 검색 매개변수를 구성합니다. `SearchResult`는 매치된 텍스트와 위치 등 각 매치에 대한 세부 정보를 보유합니다.
+
+```java
+Iterable results = parser.search("lorem", new SearchOptions(true, false, false, highlightOptions));
+```
+
+`SearchOptions` 생성자를 자세히 살펴보면:
+
+- `true`: 대소문자 구분 없는 검색 활성화.
+- `false`: 전체 단어만 일치하지 않음.
+- `false`: 정규식 패턴 검색 안 함.
+- `highlightOptions`: 우리의 강조 설정을 전달.
+
+이 설정은 대소문자를 무시하고 모든 `"lorem"` 발생을 검색하며, 강조된 스니펫을 제공합니다.
+
+### 단계 4: 검색 지원 및 결과 처리
+
+**검색 지원 여부 확인**
+일부 형식은 검색을 지원하지 않을 수 있으므로 항상 확인하세요:
+
+`parser.isSearchSupported()`는 로드된 문서 형식이 텍스트 검색을 허용하는지 여부를 나타내는 boolean을 반환합니다.
+
+```java
+if (results == null) {
+ System.out.println("Search isn't supported in this document format.");
+ return;
+}
+```
+
+**각 검색 결과 처리**
+결과를 반복하여 일치하는 스니펫을 추출하고 강조 표시와 함께 표시합니다:
+
+`SearchResult` 객체를 통해 매치된 구문과 주변 컨텍스트에 접근할 수 있습니다.
+
+```java
+for (SearchResult result : results) {
+ String snippet = String.format("%s%s%s",
+ result.getLeftHighlightItem().getText(),
+ result.getText(),
+ result.getRightHighlightItem().getText());
+ System.out.println(snippet);
+}
+```
+
+## 일반적인 문제와 해결책
+
+| 문제 | 원인 | 해결 방법 |
+|-------|--------|-----|
+| **결과가 반환되지 않음** | 문서 형식이 검색을 지원하지 않음 | `parser.isSearchSupported()`가 `true`를 반환하는지 확인하세요. |
+| **강조 반경이 너무 작음** | 기본 반경은 10자입니다. | `HighlightOptions`에서 반경을 늘리세요(예: `new HighlightOptions(20)`). |
+| **대용량 PDF에서 메모리 부족 오류** | 전체 파일이 메모리에 로드됨 | `Parser`를 스트리밍 모드로 사용하거나 파일을 청크로 처리하세요; GroupDocs.Parser는 이미 대용량 파일을 효율적으로 스트리밍합니다. |
+| **대소문자 구분이 예상대로 동작하지 않음** | `caseSensitive` 플래그가 잘못 설정됨 | `SearchOptions(true, …)`가 대소문자 구분 비활성화를 올바르게 설정했는지 확인하세요. |
+
+## 자주 묻는 질문
+
+**Q: 여러 키워드를 한 번에 검색할 수 있나요?**
+A: 직접적으로는 불가능합니다; 각 키워드를 반복하거나 원하는 모든 용어를 매치하는 정규식 패턴을 구성하세요.
+
+**Q: 강조 반경이 모든 문서 형식에 영향을 미치나요?**
+A: 대부분의 지원 형식에서는 반경이 동일하게 적용되지만, 텍스트 레이어가 없는 이미지 기반 형식은 이를 무시합니다.
+
+**Q: 강조 색상을 변경할 수 있나요?**
+A: `HighlightOptions`는 컨텍스트 반경을 제어하며, 시각적 색상은 PDF를 렌더링하는 뷰어에 따라 달라지고 파서는 직접 색상을 지정하지 않습니다.
+
+**Q: 검색이 기본적으로 대소문자를 구분하나요?**
+A: 아니요. `SearchOptions`에서 `caseSensitive`를 `false`로 설정하면 검색이 대소문자를 구분하지 않게 됩니다.
+
+**Q: 스캔한 이미지에서도 작동하나요, 아니면 텍스트 기반 파일에만 적용되나요?**
+A: 검색은 텍스트 기반 문서에서만 작동합니다. 스캔 이미지의 경우 별도의 OCR 기능이 필요하며, 이는 GroupDocs OCR에서 별도 모듈로 제공됩니다.

+# GroupDocs.Parser를 사용한 EPUB 텍스트 검색을 위한 정규식 사용 방법
+
+이 실습 가이드에서는 Java용 GroupDocs.Parser를 사용하여 EPUB 파일 내부의 텍스트를 검색하기 위해 **정규식을 사용하는 방법**을 알아봅니다. 디지털 라이브러리 인덱서를 구축하거나 수천 권의 전자책에서 특정 구문을 찾아야 할 때, 정규식 검색을 마스터하면 시간 절약과 정확도 향상에 도움이 됩니다. 설정, 핵심 클래스 및 실용적인 패턴을 단계별로 살펴보며 **EPUB 파일을 효율적으로 검색하는 방법**을 다룹니다.
+
+## 빠른 답변
+- **Java에서 EPUB을 파싱하는 라이브러리는 무엇인가요?** GroupDocs.Parser for Java.
+- **EPUB 검색에 정규식을 사용할 수 있나요?** Yes – the API accepts Java Pattern objects.
+- **대소문자 구분 검색을 수행하려면 어떻게 해야 하나요?** Set `SearchOptions.setIgnoreCase(false)`.
+- **라이선스가 필요합니까?** A free trial works for testing; a full license removes limits.
+- **필요한 Java 버전은 무엇인가요?** JDK 8 or higher.
+
+## GroupDocs.Parser란 무엇인가요?
+GroupDocs.Parser는 EPUB을 포함한 50개 이상의 문서 형식에서 텍스트, 이미지 및 메타데이터를 추출하는 Java 라이브러리입니다. 파일 처리를 추상화하는 고수준 `Parser` 클래스를 제공하여 저수준 파싱보다 검색 로직에 집중할 수 있게 합니다. 이 라이브러리는 콘텐츠를 효율적으로 스트리밍하고, 메모리 제한 환경을 지원하며, 파싱된 텍스트에 직접 작동하는 내장 검색 기능을 제공합니다.
+
+## EPUB에 대해 GroupDocs.Parser와 정규식을 사용하는 이유는?
+- **광범위한 형식 지원:** 외부 변환기 없이 EPUB을 포함한 50개 이상의 입력 형식을 처리합니다.
+- **메모리 효율적인 처리:** 콘텐츠를 스트리밍하여 전체 파일을 RAM에 로드하지 않고도 수백 페이지에 달하는 EPUB을 검색할 수 있습니다.
+- **정밀한 패턴 매칭:** 정규식을 사용하면 전체 단어, 구문 또는 복잡한 패턴(예: 날짜, ISBN) 등을 한 번의 호출로 찾을 수 있습니다.
+
+## 전제 조건
+- **Java Development Kit (JDK) 8+**가 IDE 또는 빌드 도구에 설치되고 구성되어 있어야 합니다.
+- **GroupDocs.Parser for Java** 라이브러리(Maven 또는 직접 다운로드 가능).
+- Java 구문 및 정규식 개념에 대한 기본적인 이해.
+
+## EPUB 파일에서 텍스트를 검색하기 위해 정규식을 사용하는 방법
+EPUB 파일을 `new Parser("book.epub")` 로 로드하고 컴파일된 `Pattern`을 사용하여 `search`를 호출합니다. 이 두 단계 접근 방식은 파일 로딩을 패턴 실행과 분리하여 대규모 컬렉션에서도 최적의 성능을 보장합니다.
+
+### 1단계: Parser 초기화
+`Parser` 클래스는 EPUB 파일을 로드하고 처리하기 위한 진입점입니다.
+```java
+// ```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/parser/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5
+
+
+```
+```
+
+### 2단계: 정규식 패턴 만들기
+Java의 `Pattern` 클래스는 정규식을 컴파일합니다. 예를 들어, 공백 문자 뒤에 “list”로 시작하는 모든 단어를 찾으려면 `\\slist\\w*`를 사용합니다.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+// Initialize Parser object with an EPUB file path
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.epub")) {
+ // Your code here
+}
+```
+```
+
+### 3단계: 검색 옵션 구성
+`SearchOptions`는 대소문자 구분 및 퍼지 매칭과 같은 검색 동작 방식을 구성합니다.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+String epubFilePath = "YOUR_DOCUMENT_DIRECTORY/sample.epub";
+
+try (Parser parser = new Parser(epubFilePath)) {
+ // Further processing steps go here
+}
+```
+```
+
+### 4단계: 검색 실행
+`SearchResult`는 텍스트, 페이지 번호 및 문자 오프셋을 포함하는 단일 매치를 나타냅니다.
+```java
+// ```java
+String regexPattern = \\slist; // Matches any word preceded by whitespace and 'list'
+```
+```
+
+### 5단계: 결과 처리
+`SearchResult` 컬렉션을 반복하여 매치를 로그에 기록하고, 데이터베이스에 저장하거나 인덱싱 및 알림과 같은 하위 워크플로를 트리거합니다.
+```java
+// ```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options for search
+SearchOptions options = new SearchOptions(true /* case match */, false /* whole word */, true /* fuzzy */);
+```
+```
+
+## Java에서 대소문자 구분 검색을 수행하는 방법
+정확한 대소문자 매치를 강제하려면 `SearchOptions.setIgnoreCase(false)`를 설정합니다. 이는 식별자, 코드 스니펫 또는 원래 대소문자를 유지해야 하는 브랜드 이름을 검색할 때 필수적입니다.
+
+## 일반적인 사용 사례
+1. **디지털 라이브러리 인덱싱:** 수천 개의 EPUB 제목에 대한 검색 가능한 인덱스를 자동으로 생성합니다.
+2. **콘텐츠 큐레이션:** 연구를 위해 여러 책에서 주제별 섹션(예: “Chapter 5”)을 찾아냅니다.
+3. **데이터 마이닝:** 맞춤형 정규식 패턴을 사용하여 ISBN, 날짜 또는 저자 이름과 같은 구조화된 엔터티를 추출합니다.
+4. **E‑Learning 통합:** 코스 자료 PDF 및 EPUB에 대한 즉시 전체 텍스트 검색 기능을 제공하여 교육 플랫폼을 강화합니다.
+
+## 성능 팁
+- **정규식 패턴 최적화:** CPU 사용량을 낮게 유지하기 위해 백트래킹이 많은 구조보다 간단한 문자 클래스를 선호합니다.
+- **대형 EPUB 분할:** 파일이 200 MB를 초과하면 메모리 급증을 방지하기 위해 챕터별로 개별 처리합니다.
+- **자주 사용하는 쿼리 캐시:** 인기 패턴(예: 일반 키워드)의 결과를 가벼운 인‑메모리 맵에 저장합니다.
+
+## 자주 묻는 질문
+**Q: `search`와 `extractText`의 차이점은 무엇인가요?**
+A: `search`는 정규식 패턴을 적용하여 일치하는 조각만 반환하고, `extractText`는 필터링 없이 전체 문서 내용을 반환합니다.
+
+**Q: 한 번의 호출로 여러 EPUB 파일을 검색할 수 있나요?**
+A: 단일 API 호출로 배치를 처리할 수는 없지만 파일 목록을 반복하면서 동일한 `Pattern` 및 `SearchOptions`를 각 파일에 재사용할 수 있습니다.
+
+**Q: 퍼지 검색은 어떻게 작동하나요?**
+A: `SearchOptions`에서 퍼지 모드를 활성화하면 최대 두 번의 편집 거리(Levenshtein distance)를 허용하여 오타 및 작은 변형을 포착합니다.
+
+**Q: 문서 크기에 제한이 있나요?**
+A: GroupDocs.Parser는 최대 500 MB까지의 EPUB을 처리할 수 있으며, 더 큰 파일은 직접 분할하거나 스트리밍해야 합니다.
+
+**Q: 개발에 라이선스가 필요합니까?**
+A: 무료 체험판은 사용 워터마크와 함께 전체 API 접근을 제공하고, 정식 라이선스는 제한을 제거하고 상업적 권리를 부여합니다.

+- **Do I need a license for development?** A free trial works for testing; a permanent license is required for production.
+- **Which Java version is required?** Java 8 or higher (JDK 11 recommended).
+- **Can I search multiple files at once?** Yes—wrap the parser call in a loop or use Java streams.
+- **What performance can I expect?** GroupDocs.Parser processes 500‑page HTML files in under 2 seconds on a typical server.
+
+## 정규식을 사용한 “how to search html”이란 무엇인가요?
+**“How to search html”**은 정규식을 사용하여 HTML 마크업 내부의 텍스트 패턴을 찾는 것을 의미합니다. 이 기술을 사용하면 전체 DOM 트리를 파싱하지 않고도 단어, 숫자 또는 사용자 정의 태그를 정확히 찾아낼 수 있습니다. 정규식을 원시 HTML 소스에 직접 적용함으로써 개발자는 특정 데이터를 빠르게 추출하고, 콘텐츠를 검증하거나, 섹션을 필터링할 수 있어 전체 DOM 파싱에 비해 가벼운 대안이 됩니다.
+
+## 정규식 검색에 GroupDocs.Parser for Java를 사용하는 이유
+GroupDocs.Parser는 **70+** 입력 및 출력 형식을 지원합니다—HTML, DOCX, XLSX, PDF 등을 포함—전체 파일을 메모리에 로드하지 않고도 수백 페이지 문서를 처리합니다. 기본 제공 `SearchOptions` 클래스를 통해 정규식을 활성화하고, 대소문자 구분을 제어하며, 결과 수를 제한할 수 있어 빠르고 메모리 효율적인 스캔을 제공합니다.

+**초기화**
+라이브러리를 추가한 후, Java 애플리케이션에서 GroupDocs.Parser를 사용하도록 초기화합니다:
+
+```java
+import com.groupdocs.parser.Parser;
+
+public class SetupExample {
+ public static void main(String[] args) {
+ String filePath = "path/to/your/document.html";
+ try (Parser parser = new Parser(filePath)) {
+ // Initialization complete, ready to parse and search!
+ } catch (Exception e) {
+ e.printStackTrace();
+ }
+ }
+}
+```
+
+## GroupDocs.Parser for Java를 사용하여 HTML 검색하는 방법?
+`Parser` 클래스로 HTML 파일을 로드하고 두 줄의 코드만으로 정규식 검색을 실행합니다. `Parser` 클래스는 지원되는 문서 유형을 읽고 파싱하는 진입점이며, 텍스트 추출 및 검색 메서드를 제공합니다. `SearchOptions`를 구성하면 패턴을 정규식으로 처리하도록 지정하고, 필요에 따라 대소문자 구분 또는 전체 단어 매칭을 활성화할 수 있습니다.
+
+### 단계별 구현
+
+### 단계 1: 정규식 패턴 정의
+먼저 필요한 텍스트와 일치하는 정규식 패턴을 작성합니다. 이 예제에서는 **“Sub”**으로 시작하고 뒤에 숫자가 오는 단어(예: `Sub1`, `Sub9`)를 찾습니다.
+
+```java
+String regexPattern = "Sub[0-9]";
+```
+
+### 단계 2: Search Options 설정
+`SearchOptions`는 정규식 모드와 대소문자 구분 등 검색 동작을 지정하는 구성 객체입니다.
+`SearchOptions` 객체를 구성하여 정규식 모드를 활성화하고, 대소문자 구분을 설정하며, 전체 단어만 매칭할지 여부를 결정합니다. `SearchOptions`는 파서에게 검색 방식을 알려주는 구성 보관소 역할을 합니다.
+
+```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options: case-sensitive, whole word, use regex
+SearchOptions options = new SearchOptions(true, false, true);
+```
+
+### 단계 3: 검색 실행
+HTML 파일 경로, 패턴, 옵션을 전달하여 `Parser` 인스턴스의 `search` 메서드를 호출합니다. 이 메서드는 `SearchResult` 객체 컬렉션을 반환하며, 각 객체는 매칭된 텍스트와 문서 내 위치를 포함합니다.
+
+```java
+import com.groupdocs.parser.data.SearchResult;
+
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.html")) {
+ Iterable results = parser.search(regexPattern, options);
+
+ for (SearchResult result : results) {
+ System.out.println(String.format("At %d: %s", result.getPosition(), result.getText()));
+ }
+} catch (Exception e) {
+ e.printStackTrace();
+}
+```
+
+**핵심 구성 옵션**
+- **Case Sensitivity** – 정확한 대소문자 매칭을 위해 `true`로 설정합니다.
+- **Whole Word Search** – `false`이면 부분 매칭도 포함됩니다.
+- **Use Regular Expressions** – 정규식 처리를 활성화하려면 `true`여야 합니다.
+
+## 일반적인 문제 및 해결책
+- **Incorrect file path** – HTML 파일이 애플리케이션 작업 디렉터리에서 접근 가능한지 확인하세요.
+- **Invalid regex syntax** – 코딩 전에 온라인 정규식 테스트기로 패턴을 검증하세요.
+- **Memory leaks** – `Parser` 인스턴스를 항상 닫거나 try‑with‑resources를 사용해 스트림이 해제되도록 하세요.
+
+## 실용적인 적용 사례
+HTML에서 정규식 기반 검색을 활용하면 다양한 실제 시나리오에 활용할 수 있습니다:
+
+1. **Data Extraction** – 대량 HTML 보고서에서 청구서 번호, ID, 타임스탬프 등을 추출합니다.
+2. **Content Filtering** – 금지된 키워드가 포함된 섹션을 자동으로 제거하거나 표시합니다.
+3. **Log Analysis** – HTML 형식 로그에서 오류 패턴이나 성능 지표를 스캔합니다.
+4. **ETL Pipelines** – 파서를 데이터 수집 워크플로에 통합해 웹 스크래핑된 콘텐츠를 정규화합니다.
+
+## 성능 고려 사항
+대용량 HTML 컬렉션을 처리할 때 다음 팁을 기억하세요:
+
+- **Optimize regex patterns** – 과도한 백트래킹을 피하고 가능한 경우 원자 그룹이나 소유량 수량자를 사용합니다.
+- **Streamline memory usage** – 파싱을 try‑with‑resources 블록으로 감싸 JVM이 버퍼를 즉시 회수하도록 합니다.
+- **Parallel processing** – Java `ForkJoinPool`을 활용해 여러 문서를 동시에 검색하면 멀티코어 서버에서 선형 확장이 가능합니다.
+
+## 자주 묻는 질문
+
+**Q: 정규식이란 무엇인가요?**
+A: 정규식(regex)은 문자열 내 문자 시퀀스를 매칭하기 위한 간결하고 패턴 기반의 언어로, 검증, 검색 및 텍스트 조작에 널리 사용됩니다.
+
+**Q: GroupDocs.Parser가 HTML이 아닌 파일도 처리할 수 있나요?**
+A: 네, PDF, DOCX, XLSX, PPTX 등 70개 이상의 형식을 지원하므로 동일한 검색 로직을 다양한 문서 유형에 적용할 수 있습니다.
+
+**Q: 파싱 오류는 어떻게 처리하나요?**
+A: 파싱 코드를 try‑catch 블록으로 감싸 `ParserException`을 잡아 로그를 남기고 리소스가 닫히도록 합니다.
+
+**Q: 정규식이 결과를 반환하지 않는데, 무엇이 문제인가요?**
+A: 이스케이프 문자 여부, 대소문자 구분 설정, 그리고 대상 텍스트가 실제 HTML 소스에 존재하는지 확인하세요.
+
+**Q: HTML 파일 크기 제한이 있나요?**
+A: GroupDocs.Parser는 최대 2 GB까지 처리할 수 있습니다. 매우 큰 HTML 파일은 메모리 제한을 피하기 위해 분할하거나 섹션별 스트리밍을 고려하세요.
+
+## 결론
+이 가이드를 따라 **how to search html** 문서를 GroupDocs.Parser for Java에 내장된 강력한 정규식 엔진으로 검색하는 방법을 익혔습니다. 이제 패턴을 빠르게 찾아내고 의미 있는 데이터를 추출하며, 이 솔루션을 더 큰 Java 애플리케이션이나 데이터 파이프라인에 손쉽게 통합할 수 있습니다.
+
+**Next Steps:** 더 복잡한 패턴을 실험하고, 여러 `SearchOptions`를 결합하거나, 파서를 Spring Boot 마이크로서비스에 내장해 온‑디맨드 텍스트 추출을 구현해 보세요.

+# Przetwarzanie PDF w Javie: Wyszukiwanie i podświetlanie za pomocą GroupDocs
+
+Czy kiedykolwiek czujesz się przytłoczony morzem dokumentów — PDF‑ów, plików Word czy innych formatów — i chciałbyś łatwo znaleźć konkretne słowa lub frazy? **Java PDF processing** umożliwia to. W tym przewodniku nauczysz się, jak wyszukiwać tekst w plikach PDF i generować podświetlone fragmenty przy użyciu **GroupDocs.Parser for Java**. Niezależnie od tego, czy tworzysz narzędzie do analizy dokumentów, czy automatyzujesz przegląd treści, poniższe kroki zapewniają jasne, gotowe do produkcji rozwiązanie.
+
+## Szybkie odpowiedzi
+- **Która biblioteka obsługuje wyszukiwanie tekstu PDF w Javie?** GroupDocs.Parser for Java.
+- **Czy potrzebuję licencji do rozwoju?** Tymczasowa licencja działa w testach; pełna licencja jest wymagana w produkcji.
+- **Czy mogę podświetlić wiele wystąpień jednocześnie?** Tak — ustaw promień podświetlenia i iteruj po wynikach.
+- **Czy wyszukiwanie rozróżnia wielkość liter?** Domyślnie jest niewrażliwe na wielkość liter; możesz to przełączyć za pomocą `SearchOptions`.
+- **Jakie formaty są obsługiwane?** Ponad 50 formatów wejściowych i wyjściowych, w tym PDF, DOCX, XLSX, PPTX, HTML i obrazy.
+
+## Co to jest przetwarzanie PDF w Javie?
+`Java PDF processing` to zestaw programistycznych operacji — takich jak wyodrębnianie, wyszukiwanie i podświetlanie tekstu — wykonywanych na plikach PDF przy użyciu bibliotek Java. Dzięki GroupDocs.Parser możesz przeszukiwać dowolny obsługiwany dokument, pobierać otaczający kontekst i stosować wizualne podświetlenia, wszystko bez otwierania pliku w przeglądarce. Ta funkcjonalność pozwala tworzyć szybkie, przeszukiwalne archiwa i zautomatyzowane pipeline’y przeglądu, które skalują się do tysięcy stron w jednym dokumencie.
+
+## Dlaczego warto używać GroupDocs.Parser do przetwarzania PDF w Javie?
+GroupDocs.Parser obsługuje **ponad 50 formatów plików** i może przetwarzać **PDF‑y o setkach stron** bez wczytywania całego pliku do pamięci, zmniejszając zużycie RAM o nawet **70 %** w porównaniu z naiwnymi podejściami. Jego silnik wyszukiwania zwraca precyzyjne offsety, co umożliwia tworzenie własnych podświetleń w interfejsie UI lub eksport wyników do innych systemów. Biblioteka jest aktywnie utrzymywana, kompatybilna z Java 8+ i oferuje artefakty zarówno dla Maven, jak i Gradle, co ułatwia integrację.
+
+## Wymagania wstępne
+
+Zanim zabierzemy się do pracy, upewnij się, że masz gotowe następujące niezbędne elementy:
+
+- **Środowisko programistyczne Java**: zainstalowany JDK 8+.
+- **Maven lub Gradle**: do zarządzania zależnościami i konfiguracji projektu.
+- **Biblioteka GroupDocs.Parser for Java**: pobierz lub dodaj jako zależność.
+- **Przykładowy dokument**: pliki PDF lub teksty do przeszukania.
+- **Podstawowa znajomość Javy**: znajomość klas, metod i obsługi plików.
+
+Jeśli jeszcze nie masz biblioteki, możesz pobrać najnowszą wersję z [GroupDocs Downloads](https://releases.groupdocs.com/parser/java/) lub dodać ją poprzez Maven:
+
+```xml
+
+ com.groupdocs
+ groupdocs-parser
+ 21.12
+
+```
+
+## Importowanie pakietów
+
+Na początek zaimportujmy niezbędne klasy z GroupDocs.Parser:
+
+`Parser` jest główną klasą używaną do ładowania i interakcji z dokumentami. `HighlightOptions` konfiguruje sposób podświetlania dopasowanego tekstu. `SearchOptions` definiuje zachowanie wyszukiwania, takie jak rozróżnianie wielkości liter. `SearchResult` reprezentuje pojedyncze dopasowanie znalezione w dokumencie.
+
+```java
+import com.groupdocs.parser.Parser;
+import com.groupdocs.parser.search.HighlightOptions;
+import com.groupdocs.parser.search.SearchOptions;
+import com.groupdocs.parser.search.SearchResult;
+```
+
+Te importy obejmują podstawowe funkcje parsowania dokumentów, ustawiania opcji podświetlania oraz wykonywania operacji wyszukiwania.
+
+## Jak działa przepływ pracy wyszukiwania i podświetlania?
+
+Wczytaj swój PDF, skonfiguruj obiekt `HighlightOptions`, wykonaj `parser.search`, a następnie iteruj po kolekcji `SearchResult`, aby utworzyć podświetlone fragmenty. Cały proces przebiega w dwóch krokach: najpierw parser odczytuje strukturę dokumentu; następnie silnik wyszukiwania skanuje strumień tekstu, stosując zdefiniowane opcje. Takie podejście zapewnia wysoką wydajność nawet przy dużych plikach.
+
+## Przewodnik krok po kroku: wyszukiwanie tekstu z podświetleniami
+
+Przejdźmy przez proces podzielony na przystępne, jasne kroki. Każdy krok ma własne wyjaśnienie, które pomoże zrozumieć dlaczego i jak.
+
+### Krok 1: Inicjalizacja parsera z dokumentem
+
+**Co się tutaj dzieje?**
+Tworzenie instancji klasy `Parser` powiązanej z plikiem dokumentu umożliwia dostęp i analizę jego zawartości.
+
+`Parser` ładuje dokument i udostępnia metody do wyodrębniania tekstu oraz wyszukiwania.
+
+```java
+try (Parser parser = new Parser("path/to/your/document.pdf")) {
+ // your code here
+}
+```
+
+**W praktyce:**
+Instrukcja `try-with-resources` zapewnia, że plik zostanie prawidłowo zamknięty po przetworzeniu, zapobiegając wyciekom zasobów. Zastąp `"path/to/your/document.pdf"` dokładną ścieżką do pliku lub URL.
+
+### Krok 2: Ustawienie opcji podświetlania
+
+**Dlaczego definiować opcje podświetlania?**
+Możesz chcieć kontrolować wygląd lub zachowanie podświetlania wyników wyszukiwania — na przykład liczbę znaków wyświetlanych wokół dopasowania lub kolor (jeśli jest obsługiwany).
+
+W tym przykładzie ustawiamy promień podświetlenia na 15 znaków:
+
+`HighlightOptions` określa promień kontekstu oraz ustawienia wizualne podświetlonych wyników wyszukiwania.
+
+```java
+HighlightOptions highlightOptions = new HighlightOptions(15);
+```
+
+To otacza znaleziony tekst otaczającym kontekstem — jak lupa wokół Twoich słów kluczowych — ułatwiając zauważenie, gdzie występują dopasowania.
+
+### Krok 3: Wykonanie wyszukiwania w dokumencie
+
+**Jak działa wyszukiwanie?**
+Korzystając z `parser.search`, podajesz słowo kluczowe lub frazę, opcje wyszukiwania, a następnie otrzymujesz iterowalną kolekcję obiektów `SearchResult`.
+
+`SearchOptions` konfiguruje parametry wyszukiwania, takie jak rozróżnianie wielkości liter. `SearchResult` zawiera szczegóły każdego dopasowania, w tym dopasowany tekst i jego położenie.
+
+```java
+Iterable results = parser.search("lorem", new SearchOptions(true, false, false, highlightOptions));
+```
+
+Rozbicie konstruktora `SearchOptions`:
+
+- `true`: Włącz wyszukiwanie bez rozróżniania wielkości liter.
+- `false`: Nie dopasowuj wyłącznie całych słów.
+- `false`: Nie wyszukuj wzorców regex.
+- `highlightOptions`: Przekaż naszą konfigurację podświetlania.
+
+Ta konfiguracja wyszukuje wszystkie wystąpienia `"lorem"`, ignorując wielkość liter, i zwraca podświetlone fragmenty.
+
+### Krok 4: Obsługa wsparcia wyszukiwania i wyników
+
+**Sprawdź, czy wyszukiwanie jest obsługiwane**
+Niektóre formaty mogą nie obsługiwać wyszukiwania — zawsze to potwierdzaj:
+
+`parser.isSearchSupported()` zwraca wartość boolean wskazującą, czy format załadowanego dokumentu umożliwia wyszukiwanie tekstu.
+
+```java
+if (results == null) {
+ System.out.println("Search isn't supported in this document format.");
+ return;
+}
+```
+
+**Przetwarzaj każde dopasowanie**
+Iteruj po wynikach, aby wyodrębnić i wyświetlić dopasowane fragmenty z podświetleniami:
+
+Obiekty `SearchResult` zapewniają dostęp do dopasowanej frazy oraz jej otaczającego kontekstu.
+
+```java
+for (SearchResult result : results) {
+ String snippet = String.format("%s%s%s",
+ result.getLeftHighlightItem().getText(),
+ result.getText(),
+ result.getRightHighlightItem().getText());
+ System.out.println(snippet);
+}
+```
+
+## Częste problemy i rozwiązania
+
+| Problem | Powód | Rozwiązanie |
+|-------|--------|-----|
+| **Brak wyników** | Format dokumentu nie obsługuje wyszukiwania | Sprawdź, czy `parser.isSearchSupported()` zwraca `true`. |
+| **Promień podświetlenia wydaje się za mały** | Domyślny promień to 10 znaków | Zwiększ promień w `HighlightOptions` (np. `new HighlightOptions(20)`). |
+| **Błąd braku pamięci przy dużych PDF‑ach** | Cały plik wczytywany do pamięci | Użyj `Parser` w trybie strumieniowym lub przetwarzaj plik w fragmentach; GroupDocs.Parser już efektywnie strumieniuje duże pliki. |
+| **Rozróżnianie wielkości liter nie działa zgodnie z oczekiwaniami** | Flaga `caseSensitive` ustawiona niepoprawnie | Upewnij się, że `SearchOptions(true, …)` ustawia właściwą wartość boolean dla braku rozróżniania wielkości liter. |
+
+## Najczęściej zadawane pytania
+
+**P: Czy mogę wyszukiwać wiele słów kluczowych jednocześnie?**
+O: Nie bezpośrednio; iteruj po każdym słowie kluczowym lub skonstruuj wyrażenie regularne, które dopasuje wszystkie pożądane terminy.
+
+**P: Czy promień podświetlenia wpływa na wszystkie formaty dokumentów?**
+O: Dla większości obsługiwanych formatów promień działa jednolicie; niektóre formaty oparte na obrazach go ignorują, ponieważ nie mają natywnej warstwy tekstowej.
+
+**P: Czy mogę zmienić kolory podświetlenia?**
+O: `HighlightOptions` kontroluje promień kontekstu; kolory wizualne zależą od przeglądarki PDF, której używasz do renderowania, a nie od samego parsera.
+
+**P: Czy wyszukiwanie rozróżnia wielkość liter domyślnie?**
+O: Nie. Ustawiając `caseSensitive` na `false` w `SearchOptions`, wyszukiwanie staje się niewrażliwe na wielkość liter.
+
+**P: Czy to działa z zeskanowanymi obrazami czy tylko z plikami tekstowymi?**
+O: Wyszukiwanie działa na dokumentach tekstowych. W przypadku zeskanowanych obrazów potrzebne są możliwości OCR, które zapewnia osobny moduł GroupDocs OCR.

+# Jak używać wyrażeń regularnych do wyszukiwania tekstu w plikach EPUB przy użyciu GroupDocs.Parser
+
+W tym praktycznym przewodniku odkryjesz **jak używać regex**, aby wyszukiwać tekst wewnątrz plików EPUB przy użyciu GroupDocs.Parser dla Javy. Niezależnie od tego, czy tworzysz indeksator biblioteki cyfrowej, czy potrzebujesz zlokalizować konkretne frazy w tysiącach e‑booków, opanowanie wyszukiwań wyrażeń regularnych zaoszczędzi Ci czas i zwiększy dokładność. Przejdziemy przez konfigurację, kluczowe klasy i praktyczne wzorce, jednocześnie omawiając **jak wyszukiwać epub** efektywnie.
+
+## Szybkie odpowiedzi
+- **What library parses EPUB in Java?** GroupDocs.Parser for Java.
+- **Can I use regex for EPUB search?** Yes – the API accepts Java Pattern objects.
+- **How to perform a case‑sensitive search?** Set `SearchOptions.setIgnoreCase(false)`.
+- **Do I need a license?** A free trial works for testing; a full license removes limits.
+- **Which Java version is required?** JDK 8 or higher.
+
+## Co to jest GroupDocs.Parser?
+GroupDocs.Parser to biblioteka Java, która wyodrębnia tekst, obrazy i metadane z ponad 50 formatów dokumentów, w tym EPUB. Udostępnia wysokopoziomową klasę `Parser`, która abstrahuje obsługę plików, pozwalając skupić się na logice wyszukiwania zamiast na niskopoziomowym parsowaniu. Biblioteka strumieniuje zawartość efektywnie, wspiera środowiska o ograniczonej pamięci i oferuje wbudowane możliwości wyszukiwania działające bezpośrednio na przetworzonym tekście.
+
+## Dlaczego używać regex z GroupDocs.Parser dla EPUB?
+- **Broad format support:** Handles 50+ input formats, EPUB included, without external converters.
+- **Memory‑efficient processing:** Streams content, allowing multi‑hundred‑page EPUBs to be searched without loading the entire file into RAM.
+- **Precise pattern matching:** Regex lets you locate whole words, phrases, or complex patterns (e.g., dates, ISBNs) in a single call.
+
+## Wymagania wstępne
+- **Java Development Kit (JDK) 8+** installed and configured in your IDE or build tool.
+- **GroupDocs.Parser for Java** library (available via Maven or direct download).
+- Basic familiarity with Java syntax and regular‑expression concepts.
+
+## Jak używać regex do wyszukiwania tekstu w plikach EPUB?
+
+Załaduj swój EPUB przy pomocy `new Parser("book.epub")` i wywołaj `search` używając skompilowanego `Pattern`. To dwustopniowe podejście oddziela ładowanie pliku od wykonania wzorca, zapewniając optymalną wydajność nawet przy dużych kolekcjach.
+
+### Krok 1: Inicjalizacja parsera
+Klasa `Parser` jest punktem wejścia do ładowania i obsługi pliku EPUB.
+```java
+// ```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/parser/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5
+
+
+```
+```
+
+### Krok 2: Zbuduj wzorzec regex
+Klasa `Pattern` w Javie kompiluje wyrażenie regularne. Na przykład, aby znaleźć każde słowo zaczynające się od „list” po znaku białej spacji, użyj `\\slist\\w*`.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+// Initialize Parser object with an EPUB file path
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.epub")) {
+ // Your code here
+}
+```
+```
+
+### Krok 3: Skonfiguruj opcje wyszukiwania
+`SearchOptions` konfiguruje sposób działania wyszukiwania, np. czułość na wielkość liter i dopasowanie przybliżone.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+String epubFilePath = "YOUR_DOCUMENT_DIRECTORY/sample.epub";
+
+try (Parser parser = new Parser(epubFilePath)) {
+ // Further processing steps go here
+}
+```
+```
+
+### Krok 4: Wykonaj wyszukiwanie
+`SearchResult` reprezentuje pojedyncze dopasowanie, zawierające tekst, numer strony i offsety znaków.
+```java
+// ```java
+String regexPattern = \\slist; // Matches any word preceded by whitespace and 'list'
+```
+```
+
+### Krok 5: Przetwórz wyniki
+Iteruj po kolekcji `SearchResult`, aby logować dopasowania, zapisywać je w bazie danych lub wyzwalać dalsze procesy, takie jak indeksowanie czy powiadamianie.
+```java
+// ```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options for search
+SearchOptions options = new SearchOptions(true /* case match */, false /* whole word */, true /* fuzzy */);
+```
+```
+
+## Jak wykonać wyszukiwanie rozróżniające wielkość liter w Javie?
+Ustaw `SearchOptions.setIgnoreCase(false)`, aby wymusić dopasowanie dokładnie takiej samej wielkości liter. Jest to niezbędne przy wyszukiwaniu identyfikatorów, fragmentów kodu lub nazw marek, które muszą zachować oryginalną wielkość liter.
+
+## Typowe przypadki użycia
+1. **Digital Library Indexing:** Automatically generate searchable indexes for thousands of EPUB titles.
+2. **Content Curation:** Locate thematic sections (e.g., “Chapter 5”) across multiple books for research.
+3. **Data Mining:** Extract structured entities like ISBNs, dates, or author names using tailored regex patterns.
+4. **E‑Learning Integration:** Enhance course platforms with instant full‑text search capabilities for course material PDFs and EPUBs.
+
+## Wskazówki dotyczące wydajności
+- **Optimize regex patterns:** Prefer simple character classes over back‑tracking‑heavy constructs to keep CPU usage low.
+- **Chunk large EPUBs:** Process chapters individually if the file exceeds 200 MB to avoid memory spikes.
+- **Cache frequent queries:** Store results of popular patterns (e.g., common keywords) in a lightweight in‑memory map.
+
+## Najczęściej zadawane pytania
+
+**Q: What is the difference between `search` and `extractText`?**
+A: `search` applies a regex pattern and returns only matching fragments, while `extractText` returns the entire document content without filtering.
+
+**Q: Can I search multiple EPUB files in one call?**
+A: No single API call processes a batch, but you can loop over a file list, reusing the same `Pattern` and `SearchOptions` for each file.
+
+**Q: How does fuzzy searching work?**
+A: Enable fuzzy mode in `SearchOptions` to allow a Levenshtein distance of up to two edits, which captures misspellings and minor variations.
+
+**Q: Is there a limit on document size?**
+A: GroupDocs.Parser can handle EPUBs up to 500 MB; larger files should be split or streamed manually.
+
+**Q: Do I need a license for development?**
+A: A free trial provides full API access with a usage watermark; a permanent license removes restrictions and grants commercial rights.

+
+**Inicjalizacja**
+Po dodaniu biblioteki zainicjalizuj aplikację Java, aby korzystała z GroupDocs.Parser:
+
+```java
+import com.groupdocs.parser.Parser;
+
+public class SetupExample {
+ public static void main(String[] args) {
+ String filePath = "path/to/your/document.html";
+ try (Parser parser = new Parser(filePath)) {
+ // Initialization complete, ready to parse and search!
+ } catch (Exception e) {
+ e.printStackTrace();
+ }
+ }
+}
+```
+
+## Jak przeszukiwać HTML przy użyciu GroupDocs.Parser dla Javy?
+Wczytaj plik HTML za pomocą klasy `Parser` i wykonaj wyszukiwanie regex w zaledwie dwóch linijkach kodu. Klasa `Parser` jest punktem wejścia, który odczytuje i parsuje obsługiwane typy dokumentów, udostępniając metody do wyodrębniania tekstu i wyszukiwania. Konfigurując `SearchOptions`, informujesz parser, aby traktował podany wzorzec jako wyrażenie regularne, opcjonalnie włączając dopasowanie uwzględniające wielkość liter lub całe wyrazy.
+
+### Implementacja krok po kroku
+
+### Krok 1: Zdefiniuj swój wzorzec wyrażenia regularnego
+Najpierw utwórz wzorzec regex, który pasuje do potrzebnego tekstu. W tym przykładzie szukamy słów zaczynających się od **„Sub”** i zakończonych cyfrą (np. `Sub1`, `Sub9`).
+
+```java
+String regexPattern = "Sub[0-9]";
+```
+
+### Krok 2: Skonfiguruj opcje wyszukiwania
+`SearchOptions` to obiekt konfiguracyjny określający zachowanie wyszukiwania, takie jak tryb regex i czułość na wielkość liter.
+Skonfiguruj obiekt `SearchOptions`, aby aktywować tryb regex, ustawić czułość na wielkość liter i zdecydować, czy dopasowywać tylko całe wyrazy. `SearchOptions` jest kontenerem ustawień, który instruuje parser, jak wykonać wyszukiwanie.
+
+```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options: case-sensitive, whole word, use regex
+SearchOptions options = new SearchOptions(true, false, true);
+```
+
+### Krok 3: Wykonaj wyszukiwanie
+Wywołaj metodę `search` na instancji `Parser`, przekazując ścieżkę do pliku HTML, wzorzec oraz opcje. Metoda zwraca kolekcję obiektów `SearchResult`, z których każdy zawiera dopasowany tekst i jego położenie w dokumencie.
+
+```java
+import com.groupdocs.parser.data.SearchResult;
+
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.html")) {
+ Iterable results = parser.search(regexPattern, options);
+
+ for (SearchResult result : results) {
+ System.out.println(String.format("At %d: %s", result.getPosition(), result.getText()));
+ }
+} catch (Exception e) {
+ e.printStackTrace();
+}
+```
+
+**Kluczowe opcje konfiguracyjne**
+- **Czułość na wielkość liter** – ustaw `true`, aby wymagać dokładnego dopasowania wielkości.
+- **Wyszukiwanie całych wyrazów** – `false` pozwala na dopasowania częściowe.
+- **Użycie wyrażeń regularnych** – musi być `true`, aby włączyć przetwarzanie regex.
+
+## Typowe problemy i rozwiązania
+- **Nieprawidłowa ścieżka pliku** – sprawdź, czy plik HTML jest dostępny z katalogu roboczego aplikacji.
+- **Błędna składnia regex** – przetestuj wzorzec w internetowym testerze regex przed umieszczeniem go w kodzie.
+- **Wycieki pamięci** – zawsze zamykaj instancję `Parser` lub używaj try‑with‑resources, aby zapewnić zwolnienie strumieni.
+
+## Praktyczne zastosowania
+Stosowanie wyszukiwań opartych na regex w HTML otwiera wiele realnych scenariuszy:
+
+1. **Ekstrakcja danych** – wyciąganie numerów faktur, identyfikatorów lub znaczników czasu z masowych raportów HTML.
+2. **Filtrowanie treści** – automatyczne usuwanie lub oznaczanie sekcji zawierających zakazane słowa kluczowe.
+3. **Analiza logów** – skanowanie logów w formacie HTML pod kątem wzorców błędów lub metryk wydajności.
+4. **Potoki ETL** – integracja parsera w procesach pobierania danych, które normalizują treści pobrane ze stron internetowych.
+
+## Rozważania dotyczące wydajności
+Przy obsłudze dużych zbiorów HTML pamiętaj o następujących wskazówkach:
+
+- **Optymalizuj wzorce regex** – unikaj nadmiernego backtrackingu; stosuj grupy atomowe lub kwantyfikatory posesywne, gdy to możliwe.
+- **Usprawnij zużycie pamięci** – otaczaj parsowanie blokiem try‑with‑resources, aby JVM mogło szybko zwolnić bufory.
+- **Przetwarzanie równoległe** – wykorzystaj `ForkJoinPool` Javy do jednoczesnego przeszukiwania wielu dokumentów, skalując liniowo na serwerach wielordzeniowych.
+
+## Najczęściej zadawane pytania
+
+**Q: Czym jest wyrażenie regularne?**
+A: Wyrażenie regularne (regex) to zwięzły język oparty na wzorcach służący do dopasowywania sekwencji znaków w łańcuchach, szeroko używany do walidacji, wyszukiwania i manipulacji tekstem.
+
+**Q: Czy GroupDocs.Parser obsługuje pliki nie‑HTML?**
+A: Tak, obsługuje ponad 70 formatów — w tym PDF, DOCX, XLSX i PPTX — więc ta sama logika wyszukiwania działa w różnych typach dokumentów.
+
+**Q: Jak obsługiwać błędy parsowania?**
+A: Otaczaj kod parsowania blokiem try‑catch, przechwytując `ParserException`, aby zalogować problem i zapewnić zamknięcie zasobów.
+
+**Q: Mój regex nie zwraca wyników — co jest nie tak?**
+A: Sprawdź, czy wzorzec ma poprawnie escapowane znaki, zweryfikuj ustawienia czułości na wielkość liter i upewnij się, że docelowy tekst rzeczywiście występuje w źródle HTML.
+
+**Q: Czy istnieje limit rozmiaru plików HTML?**
+A: GroupDocs.Parser może przetwarzać pliki do 2 GB; w przypadku bardzo dużych plików rozważ ich podział lub strumieniowe przetwarzanie fragmentów, aby nie przekroczyć ograniczeń pamięci.
+
+## Zakończenie
+Korzystając z tego przewodnika, wiesz już **jak przeszukiwać html** przy użyciu potężnego silnika regex wbudowanego w GroupDocs.Parser dla Javy. Możesz szybko lokalizować wzorce, wyodrębniać istotne dane i integrować rozwiązanie w większych aplikacjach Java lub potokach danych.
+
+**Kolejne kroki:** eksperymentuj z bardziej złożonymi wzorcami, łącz wielokrotne `SearchOptions` lub osadź parser w mikroserwisie Spring Boot, aby zapewnić wyodrębnianie tekstu na żądanie.

+# Processamento de PDF em Java: Busca e Realce com GroupDocs
+
+Já se pegou afogado em um mar de documentos—PDFs, arquivos Word ou outros formatos—e desejando encontrar palavras ou frases específicas com facilidade? **Java PDF processing** torna isso possível. Neste guia, você aprenderá como buscar texto dentro de PDFs e gerar trechos realçados usando **GroupDocs.Parser for Java**. Seja construindo uma ferramenta de análise de documentos ou automatizando a revisão de conteúdo, os passos abaixo fornecem uma solução clara e pronta para produção.
+
+## Respostas Rápidas
+- **Qual biblioteca lida com a busca de texto em PDF em Java?** GroupDocs.Parser for Java.
+- **Preciso de uma licença para desenvolvimento?** Uma licença temporária funciona para testes; uma licença completa é necessária para produção.
+- **Posso realçar múltiplas ocorrências de uma vez?** Sim—defina um raio de realce e itere sobre os resultados.
+- **A busca diferencia maiúsculas de minúsculas?** Por padrão, não diferencia; você pode alternar isso via `SearchOptions`.
+- **Quais formatos são suportados?** Mais de 50 formatos de entrada e saída, incluindo PDF, DOCX, XLSX, PPTX, HTML e imagens.
+
+## O que é o processamento de PDF em Java?
+`Java PDF processing` é o conjunto de operações programáticas—como extração, busca e realce de texto—executadas em arquivos PDF usando bibliotecas Java. Com o GroupDocs.Parser você pode buscar em qualquer documento suportado, recuperar o contexto ao redor e aplicar realces visuais, tudo sem abrir o arquivo em um visualizador. Essa capacidade permite construir arquivos rápidos e pesquisáveis e pipelines de revisão automatizadas que escalam para milhares de páginas por documento.
+
+## Por que usar o GroupDocs.Parser para o processamento de PDF em Java?
+O GroupDocs.Parser suporta **mais de 50 formatos de arquivo** e pode processar **PDFs com centenas de páginas** sem carregar o arquivo inteiro na memória, reduzindo o uso de RAM em até **70 %** comparado a abordagens ingênuas. Seu motor de busca retorna deslocamentos precisos, permitindo que você crie realces de UI personalizados ou exporte resultados para outros sistemas. A biblioteca é mantida ativamente, compatível com Java 8+ e oferece artefatos Maven e Gradle para fácil integração.
+
+## Pré-requisitos
+
+- **Ambiente de Desenvolvimento Java**: JDK 8+ instalado.
+- **Maven ou Gradle**: Para gerenciamento de dependências e configuração do projeto.
+- **Biblioteca GroupDocs.Parser for Java**: Baixe ou adicione via dependência.
+- **Um documento de exemplo**: PDFs ou textos de teste para buscar.
+- **Conhecimento básico de Java**: Familiaridade com classes, métodos e manipulação de arquivos.
+
+Se ainda não possui a biblioteca, você pode obter a versão mais recente em [GroupDocs Downloads](https://releases.groupdocs.com/parser/java/) ou adicioná‑la via Maven:
+
+```xml
+
+ com.groupdocs
+ groupdocs-parser
+ 21.12
+
+```
+
+## Importar Pacotes
+
+Para começar, vamos importar as classes essenciais do GroupDocs.Parser:
+
+`Parser` é a classe principal usada para carregar e interagir com documentos. `HighlightOptions` configura como o texto correspondido é realçado. `SearchOptions` define o comportamento da busca, como sensibilidade a maiúsculas/minúsculas. `SearchResult` representa uma correspondência individual encontrada no documento.
+
+```java
+import com.groupdocs.parser.Parser;
+import com.groupdocs.parser.search.HighlightOptions;
+import com.groupdocs.parser.search.SearchOptions;
+import com.groupdocs.parser.search.SearchResult;
+```
+
+Essas importações cobrem funcionalidades principais para analisar documentos, definir opções de realce e executar operações de busca.
+
+## Como funciona o fluxo de trabalho de busca e realce?
+
+Carregue seu PDF, configure um objeto `HighlightOptions`, execute `parser.search` e então itere sobre a coleção `SearchResult` para construir trechos realçados. Todo o processo ocorre em duas etapas: primeiro, o parser lê a estrutura do documento; segundo, o motor de busca varre o fluxo de texto aplicando as opções definidas. Essa abordagem garante alto desempenho mesmo em arquivos grandes.
+
+## Guia Passo a Passo para Buscar Texto com Realces
+
+Vamos percorrer o processo subdividido em etapas manejáveis e claras. Cada etapa tem sua própria explicação para ajudá‑lo a entender o porquê e o como.
+
+### Etapa 1: Inicializar o Parser com Seu Documento
+
+**O que está acontecendo aqui?**
+Criar uma instância da classe `Parser` vinculada ao seu arquivo de documento permite acessar e analisar seu conteúdo.
+
+`Parser` carrega um documento e fornece métodos para extração de texto e busca.
+
+```java
+try (Parser parser = new Parser("path/to/your/document.pdf")) {
+ // your code here
+}
+```
+
+**Na prática:**
+A instrução `try-with-resources` garante que seu arquivo seja fechado corretamente após o processamento, evitando vazamentos de recursos. Substitua `"path/to/your/document.pdf"` pelo caminho exato do seu arquivo ou URL.
+
+### Etapa 2: Configurar Opções de Realce
+
+**Por que definir opções de realce?**
+Você pode querer controlar a aparência ou o comportamento de como os resultados da busca são realçados—como o número de caracteres a mostrar ao redor da correspondência ou a cor (se suportada).
+
+Neste exemplo, definimos um raio de realce de 15 caracteres:
+
+`HighlightOptions` especifica o raio de contexto e as configurações visuais para os resultados de busca realçados.
+
+```java
+HighlightOptions highlightOptions = new HighlightOptions(15);
+```
+
+Isso envolve o texto encontrado com o contexto ao redor—como uma lupa ao redor das suas palavras‑chave—facilitando a visualização de onde as correspondências ocorrem.
+
+### Etapa 3: Executar a Busca no Documento
+
+**Como a busca funciona?**
+Usando `parser.search`, você especifica a palavra‑chave ou frase, as opções de busca e então obtém uma coleção iterável de objetos `SearchResult`.
+
+`SearchOptions` configura parâmetros de busca como sensibilidade a maiúsculas/minúsculas. `SearchResult` contém detalhes de cada correspondência, incluindo o texto encontrado e sua localização.
+
+```java
+Iterable results = parser.search("lorem", new SearchOptions(true, false, false, highlightOptions));
+```
+
+Desmembrando o construtor `SearchOptions`:
+
+- `true`: Habilita busca sem diferenciação de maiúsculas/minúsculas.
+- `false`: Não corresponde apenas a palavras inteiras.
+- `false`: Não busca por padrões regex.
+- `highlightOptions`: Passa nossa configuração de realce.
+
+Esta configuração busca todas as ocorrências de `"lorem"`, ignorando maiúsculas/minúsculas, e com trechos realçados.
+
+### Etapa 4: Manipular Suporte à Busca e Resultados
+
+**Verificar se a busca é suportada**
+Alguns formatos podem não suportar busca — sempre confirme:
+
+`parser.isSearchSupported()` retorna um boolean indicando se o formato do documento carregado permite busca de texto.
+
+```java
+if (results == null) {
+ System.out.println("Search isn't supported in this document format.");
+ return;
+}
+```
+
+**Processar cada resultado de busca**
+Itere pelos resultados para extrair e exibir trechos correspondentes com realces:
+
+Objetos `SearchResult` dão acesso à frase correspondida e ao seu contexto ao redor.
+
+```java
+for (SearchResult result : results) {
+ String snippet = String.format("%s%s%s",
+ result.getLeftHighlightItem().getText(),
+ result.getText(),
+ result.getRightHighlightItem().getText());
+ System.out.println(snippet);
+}
+```
+
+## Problemas Comuns e Soluções
+
+| Problema | Motivo | Correção |
+|----------|--------|----------|
+| **Nenhum resultado retornado** | Formato do documento não pesquisável | Verifique se `parser.isSearchSupported()` retorna `true`. |
+| **O raio de realce parece muito pequeno** | O raio padrão é de 10 caracteres | Aumente o raio em `HighlightOptions` (ex.: `new HighlightOptions(20)`). |
+| **Erro de falta de memória em PDFs grandes** | Arquivo inteiro carregado na memória | Use `Parser` em modo de streaming ou processe o arquivo em partes; o GroupDocs.Parser já faz streaming de arquivos grandes de forma eficiente. |
+| **Sensibilidade a maiúsculas/minúsculas não se comporta como esperado** | Flag `caseSensitive` configurada incorretamente | Certifique‑se de que `SearchOptions(true, …)` define o boolean correto para insensibilidade a maiúsculas/minúsculas. |
+
+## Perguntas Frequentes
+
+**Q: Posso buscar múltiplas palavras‑chave de uma vez?**
+A: Não diretamente; itere sobre cada palavra‑chave ou construa um padrão regex que corresponda a todos os termos desejados.
+
+**Q: O raio de realce afeta todos os formatos de documento?**
+A: Na maioria dos formatos suportados o raio funciona uniformemente; alguns formatos baseados em imagem o ignoram porque não possuem camadas de texto nativas.
+
+**Q: Posso mudar as cores de realce?**
+A: `HighlightOptions` controla o raio de contexto; as cores visuais dependem do visualizador que você usa para renderizar o PDF, não do parser em si.
+
+**Q: A busca diferencia maiúsculas/minúsculas por padrão?**
+A: Não. Definindo `caseSensitive` como `false` em `SearchOptions`, a busca torna‑se insensível a maiúsculas/minúsculas.
+
+**Q: Isso funciona com imagens escaneadas ou apenas arquivos baseados em texto?**
+A: A busca funciona em documentos baseados em texto. Para imagens escaneadas, você precisa de capacidades OCR, que o GroupDocs OCR fornece como módulo separado.

Seja construindo um indexador de biblioteca digital ou precisando localizar frases específicas em milhares de e‑books, dominar buscas com expressões regulares economizará tempo e melhorará a precisão. Vamos percorrer a configuração, classes principais e padrões práticos, tudo enquanto cobrimos **como buscar arquivos epub** de forma eficiente.
+
+## Respostas Rápidas
+- **Qual biblioteca analisa EPUB em Java?** GroupDocs.Parser for Java.
+- **Posso usar regex para busca em EPUB?** Sim – a API aceita objetos Java Pattern.
+- **Como executar uma busca sensível a maiúsculas/minúsculas?** Defina `SearchOptions.setIgnoreCase(false)`.
+- **Preciso de uma licença?** Um teste gratuito funciona para testes; uma licença completa remove limites.
+- **Qual versão do Java é necessária?** JDK 8 ou superior.
+
+## O que é GroupDocs.Parser?
+GroupDocs.Parser é uma biblioteca Java que extrai texto, imagens e metadados de mais de 50 formatos de documentos, incluindo EPUB. Ela fornece uma classe de alto nível `Parser` que abstrai o manuseio de arquivos, permitindo que você se concentre na lógica de busca em vez do parsing de baixo nível. A biblioteca transmite conteúdo de forma eficiente, suporta ambientes com memória limitada e oferece recursos de busca integrados que funcionam diretamente no texto analisado.
+
+## Por que Usar Regex com GroupDocs.Parser para EPUB?
+- **Suporte amplo a formatos:** Lida com mais de 50 formatos de entrada, incluindo EPUB, sem conversores externos.
+- **Processamento eficiente em memória:** Transmite o conteúdo, permitindo que EPUBs com centenas de páginas sejam pesquisados sem carregar o arquivo inteiro na RAM.
+- **Correspondência de padrões precisa:** Regex permite localizar palavras inteiras, frases ou padrões complexos (por exemplo, datas, ISBNs) em uma única chamada.
+
+## Pré-requisitos
+- **Java Development Kit (JDK) 8+** instalado e configurado em sua IDE ou ferramenta de build.
+- **GroupDocs.Parser for Java** (biblioteca disponível via Maven ou download direto).
+- Familiaridade básica com a sintaxe Java e conceitos de expressões regulares.
+
+## Como Usar Regex para Buscar Texto em Arquivos EPUB?
+Carregue seu EPUB com `new Parser("book.epub")` e invoque `search` usando um `Pattern` compilado. Essa abordagem em duas etapas isola o carregamento do arquivo da execução do padrão, garantindo desempenho ideal mesmo em coleções grandes.
+
+### Etapa 1: Inicializar o Parser
+A classe `Parser` é o ponto de entrada para carregar e manipular um arquivo EPUB.
+```java
+// ```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/parser/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5
+
+
+```
+```
+
+### Etapa 2: Construir um Padrão Regex
+A classe `Pattern` do Java compila a expressão regular. Por exemplo, para encontrar qualquer palavra que comece com “list” após um caractere de espaço, use `\\slist\\w*`.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+// Initialize Parser object with an EPUB file path
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.epub")) {
+ // Your code here
+}
+```
+```
+
+### Etapa 3: Configurar Opções de Busca
+`SearchOptions` configura como a busca opera, como sensibilidade a maiúsculas/minúsculas e correspondência difusa.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+String epubFilePath = "YOUR_DOCUMENT_DIRECTORY/sample.epub";
+
+try (Parser parser = new Parser(epubFilePath)) {
+ // Further processing steps go here
+}
+```
+```
+
+### Etapa 4: Executar a Busca
+`SearchResult` representa uma correspondência única, incluindo texto, número da página e deslocamentos de caracteres.
+```java
+// ```java
+String regexPattern = \\slist; // Matches any word preceded by whitespace and 'list'
+```
+```
+
+### Etapa 5: Processar os Resultados
+Itere sobre a coleção `SearchResult` para registrar correspondências, armazená‑las em um banco de dados ou acionar fluxos de trabalho subsequentes, como indexação ou alertas.
+```java
+// ```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options for search
+SearchOptions options = new SearchOptions(true /* case match */, false /* whole word */, true /* fuzzy */);
+```
+```
+
+## Como Executar uma Busca Sensível a Maiúsculas/Minúsculas em Java?
+Defina `SearchOptions.setIgnoreCase(false)` para impor correspondência exata de maiúsculas/minúsculas. Isso é essencial ao buscar identificadores, trechos de código ou nomes de marcas que devem manter a capitalização original.
+
+## Casos de Uso Comuns
+1. **Indexação de Biblioteca Digital:** Gera automaticamente índices pesquisáveis para milhares de títulos EPUB.
+2. **Curadoria de Conteúdo:** Localiza seções temáticas (por exemplo, “Capítulo 5”) em vários livros para pesquisa.
+3. **Mineração de Dados:** Extrai entidades estruturadas como ISBNs, datas ou nomes de autores usando padrões regex personalizados.
+4. **Integração de E‑Learning:** Aprimora plataformas de cursos com busca instantânea de texto completo para PDFs e EPUBs de material de curso.
+
+## Dicas de Performance
+- **Otimizar padrões regex:** Prefira classes de caracteres simples em vez de construções que causem back‑tracking intenso para manter o uso de CPU baixo.
+- **Dividir EPUBs grandes:** Processar capítulos individualmente se o arquivo exceder 200 MB para evitar picos de memória.
+- **Cache de consultas frequentes:** Armazene resultados de padrões populares (por exemplo, palavras‑chave comuns) em um mapa leve na memória.
+
+## Perguntas Frequentes
+
+**Q: Qual é a diferença entre `search` e `extractText`?**
+**A:** `search` aplica um padrão regex e retorna apenas fragmentos correspondentes, enquanto `extractText` devolve todo o conteúdo do documento sem filtragem.
+
+**Q: Posso buscar múltiplos arquivos EPUB em uma única chamada?**
+**A:** Nenhuma chamada única da API processa um lote, mas você pode iterar sobre uma lista de arquivos, reutilizando o mesmo `Pattern` e `SearchOptions` para cada arquivo.
+
+**Q: Como funciona a busca difusa?**
+**A:** Ative o modo difuso em `SearchOptions` para permitir uma distância de Levenshtein de até duas edições, capturando erros de digitação e variações menores.
+
+**Q: Existe um limite de tamanho de documento?**
+**A:** O GroupDocs.Parser pode lidar com EPUBs de até 500 MB; arquivos maiores devem ser divididos ou transmitidos manualmente.
+
+**Q: Preciso de uma licença para desenvolvimento?**
+**A:** Um teste gratuito fornece acesso total à API com marca d'água de uso; uma licença permanente remove restrições e concede direitos comerciais.

+# Como Pesquisar HTML Usando GroupDocs.Parser para Java
+
+Pesquisar arquivos HTML massivos em busca de padrões específicos pode parecer procurar uma agulha no palheiro. **How to search html** eficientemente é uma pergunta comum para desenvolvedores Java que precisam extrair dados, filtrar conteúdo ou automatizar a análise de relatórios. Neste tutorial você descobrirá uma abordagem prática, baseada em regex, impulsionada pelo **GroupDocs.Parser for Java** — desde a configuração até a solução de problemas — para que você possa localizar com confiança qualquer padrão de texto dentro de documentos HTML.
+
+## Respostas Rápidas
+- **Qual biblioteca lida com pesquisa regex em HTML no Java?** GroupDocs.Parser for Java.
+- **Preciso de uma licença para desenvolvimento?** Um teste gratuito funciona para testes; uma licença permanente é necessária para produção.
+- **Qual versão do Java é necessária?** Java 8 ou superior (JDK 11 recomendado).
+- **Posso pesquisar vários arquivos ao mesmo tempo?** Sim—envolva a chamada do parser em um loop ou use streams do Java.
+- **Qual desempenho posso esperar?** GroupDocs.Parser processa arquivos HTML de 500 páginas em menos de 2 segundos em um servidor típico.
+
+## O que é “how to search html” com regex?
+**“How to search html”** refere-se ao uso de expressões regulares para localizar padrões de texto dentro da marcação HTML. Essa técnica permite identificar palavras, números ou tags personalizadas sem analisar toda a árvore DOM. Aplicando regex diretamente ao código-fonte HTML bruto, os desenvolvedores podem extrair rapidamente dados específicos, validar conteúdo ou filtrar seções, tornando-a uma alternativa leve ao parsing completo do DOM.
+
+## Por que usar GroupDocs.Parser para Java para pesquisas regex?
+GroupDocs.Parser suporta **70+** formatos de entrada e saída — incluindo HTML, DOCX, XLSX e PDF — enquanto processa documentos com centenas de páginas sem carregar o arquivo inteiro na memória. Sua classe nativa `SearchOptions` permite habilitar expressões regulares, controlar a sensibilidade a maiúsculas/minúsculas e limitar resultados, proporcionando varreduras rápidas e eficientes em memória.
+
+## Pré-requisitos
+Antes de mergulhar, certifique‑se de que você tem:
+
+1. **GroupDocs.Parser for Java** (versão mais recente, por exemplo, 25.5 ou mais nova).
+2. **Java Development Kit** 8 ou posterior instalado e configurado na sua IDE.
+3. Familiaridade básica com **sintaxe regex do Java** (por exemplo, `\d+`, `\bSub\w*`).
+
+## Configurando GroupDocs.Parser para Java
+Para começar, adicione a dependência Maven ao seu `pom.xml`:
+
+```xml
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5
+
+```
+
+Para downloads diretos, visite [GroupDocs.Parser for Java releases](https://releases.groupdocs.com/parser/java/) para obter a versão mais recente.
+
+**Aquisição de Licença**
+- **Free Trial** – explore os recursos principais sem custo.
+- **Temporary License** – solicite uma chave de teste estendida no [GroupDocs' website](https://purchase.groupdocs.com/temporary-license/).
+- **Purchase** – obtenha uma licença completa para uso ilimitado em produção.
+
+**Inicialização**
+Uma vez que a biblioteca esteja adicionada, inicialize sua aplicação Java para usar GroupDocs.Parser:
+
+```java
+import com.groupdocs.parser.Parser;
+
+public class SetupExample {
+ public static void main(String[] args) {
+ String filePath = "path/to/your/document.html";
+ try (Parser parser = new Parser(filePath)) {
+ // Initialization complete, ready to parse and search!
+ } catch (Exception e) {
+ e.printStackTrace();
+ }
+ }
+}
+```
+
+## Como Pesquisar HTML Usando GroupDocs.Parser para Java?
+Carregue seu arquivo HTML com a classe `Parser` e execute uma pesquisa regex em apenas duas linhas de código. A classe `Parser` é o ponto de entrada que lê e analisa os tipos de documentos suportados, expondo métodos para extração de texto e pesquisa. Ao configurar `SearchOptions`, você indica ao parser que seu padrão deve ser tratado como uma expressão regular, podendo habilitar opcionalmente a correspondência sensível a maiúsculas/minúsculas ou de palavra inteira.
+
+### Implementação Passo a Passo
+
+### Etapa 1: Defina Seu Padrão de Expressão Regular
+Primeiro, crie o padrão regex que corresponde ao texto que você precisa. Neste exemplo buscamos palavras que começam com **“Sub”** seguidas por um dígito (ex.: `Sub1`, `Sub9`).
+
+```java
+String regexPattern = "Sub[0-9]";
+```
+
+### Etapa 2: Configurar Opções de Pesquisa
+`SearchOptions` é um objeto de configuração que especifica o comportamento da pesquisa, como modo regex e sensibilidade a maiúsculas/minúsculas.
+Configure o objeto `SearchOptions` para ativar o modo regex, definir a sensibilidade a maiúsculas/minúsculas e decidir se deve corresponder apenas a palavras inteiras. `SearchOptions` é um contêiner de configuração que informa ao parser como executar a pesquisa.
+
+```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options: case-sensitive, whole word, use regex
+SearchOptions options = new SearchOptions(true, false, true);
+```
+
+### Etapa 3: Executar a Pesquisa
+Invoque o método `search` em uma instância de `Parser`, passando o caminho do arquivo HTML, o padrão e as opções. O método retorna uma coleção de objetos `SearchResult`, cada um contendo o texto correspondido e sua localização no documento.
+
+```java
+import com.groupdocs.parser.data.SearchResult;
+
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.html")) {
+ Iterable results = parser.search(regexPattern, options);
+
+ for (SearchResult result : results) {
+ System.out.println(String.format("At %d: %s", result.getPosition(), result.getText()));
+ }
+} catch (Exception e) {
+ e.printStackTrace();
+}
+```
+
+**Opções de Configuração Principais**
+- **Case Sensitivity** – defina `true` para correspondências exatas de maiúsculas/minúsculas.
+- **Whole Word Search** – `false` inclui correspondências parciais.
+- **Use Regular Expressions** – deve ser `true` para habilitar o processamento de regex.
+
+## Problemas Comuns e Soluções
+- **Incorrect file path** – verifique se o arquivo HTML está acessível a partir do diretório de trabalho da sua aplicação.
+- **Invalid regex syntax** – teste seu padrão com um validador de regex online antes de incorporá‑lo ao código.
+- **Memory leaks** – sempre feche a instância `Parser` ou use try‑with‑resources para garantir que os streams sejam liberados.
+
+## Aplicações Práticas
+Empregar pesquisas guiadas por regex em HTML abre portas para diversos cenários reais:
+
+1. **Data Extraction** – extraia números de nota fiscal, IDs ou timestamps de relatórios HTML em massa.
+2. **Content Filtering** – remova ou sinalize automaticamente seções contendo palavras‑chave proibidas.
+3. **Log Analysis** – analise logs formatados em HTML em busca de padrões de erro ou métricas de desempenho.
+4. **ETL Pipelines** – integre o parser em fluxos de ingestão de dados que normalizam conteúdo raspado da web.
+
+## Considerações de Desempenho
+Ao lidar com grandes corpora de HTML, mantenha estas dicas em mente:
+
+- **Optimize regex patterns** – evite backtracking excessivo; use grupos atômicos ou quantificadores possessivos quando possível.
+- **Streamline memory usage** – envolva o parsing em um bloco try‑with‑resources para que a JVM recupere buffers prontamente.
+- **Parallel processing** – aproveite o `ForkJoinPool` do Java para pesquisar múltiplos documentos simultaneamente, escalando linearmente em servidores multi‑core.
+
+## Perguntas Frequentes
+
+**Q: O que é uma expressão regular?**
+A: Uma expressão regular (regex) é uma linguagem concisa baseada em padrões para corresponder sequências de caracteres dentro de strings, amplamente usada para validação, busca e manipulação de texto.
+
+**Q: O GroupDocs.Parser pode lidar com arquivos que não sejam HTML?**
+A: Sim, ele suporta mais de 70 formatos — incluindo PDF, DOCX, XLSX e PPTX — de modo que a mesma lógica de pesquisa funciona em diversos tipos de documentos.
+
+**Q: Como devo tratar erros de parsing?**
+A: Envolva o código de parsing em um bloco try‑catch, capturando `ParserException` para registrar o problema e garantir que os recursos sejam fechados.
+
+**Q: Meu regex não retorna resultados — o que há de errado?**
+A: Verifique novamente o padrão quanto a caracteres escapados, confirme as configurações de sensibilidade a maiúsculas/minúsculas e assegure‑se de que o texto alvo realmente exista no código‑fonte HTML.
+
+**Q: Existe um limite de tamanho para arquivos HTML?**
+A: O GroupDocs.Parser pode processar arquivos de até 2 GB; para arquivos HTML extremamente grandes, considere dividi‑los ou fazer streaming de seções para permanecer dentro dos limites de memória.
+
+## Conclusão
+Seguindo este guia, você agora sabe **how to search html** em documentos usando um poderoso motor de regex incorporado ao GroupDocs.Parser para Java. Você pode localizar rapidamente padrões, extrair dados significativos e integrar a solução em aplicações Java maiores ou pipelines de dados.
+
+**Próximos Passos:** experimente padrões mais complexos, combine múltiplas `SearchOptions` ou incorpore o parser em um microserviço Spring Boot para extração de texto sob demanda.

+# Обработка PDF в Java: Поиск и выделение с GroupDocs
+
+Когда‑то вы чувствуете, что тонете в море документов — PDF, Word‑файлах или других форматах — и хотите без усилий находить конкретные слова или фразы? **Java PDF processing** делает это возможным. В этом руководстве вы узнаете, как искать текст внутри PDF и генерировать выделенные фрагменты с помощью **GroupDocs.Parser for Java**. Независимо от того, создаёте ли вы инструмент анализа документов или автоматизируете проверку контента, нижеописанные шаги предоставят вам чёткое, готовое к продакшну решение.
+
+## Быстрые ответы
+- **Какая библиотека обрабатывает поиск текста PDF в Java?** GroupDocs.Parser for Java.
+- **Нужна ли лицензия для разработки?** Временная лицензия подходит для тестирования; полная лицензия требуется для продакшна.
+- **Могу ли я выделять несколько вхождений одновременно?** Да — задайте радиус выделения и пройдитесь по результатам.
+- **Поиск чувствителен к регистру?** По умолчанию поиск нечувствителен к регистру; вы можете переключить его через `SearchOptions`.
+- **Какие форматы поддерживаются?** Более 50 входных и выходных форматов, включая PDF, DOCX, XLSX, PPTX, HTML и изображения.
+
+## Что такое обработка PDF в Java?
+`Java PDF processing` — это набор программных операций, таких как извлечение, поиск и выделение текста, выполняемых над PDF‑файлами с помощью Java‑библиотек. С GroupDocs.Parser вы можете искать любой поддерживаемый документ, получать окружающий контекст и применять визуальные выделения, не открывая файл в просмотрщике. Эта возможность позволяет создавать быстрые, поисковые архивы и автоматизированные конвейеры проверки, масштабируемые до тысяч страниц в документе.
+
+## Почему стоит использовать GroupDocs.Parser для обработки PDF в Java?
+GroupDocs.Parser поддерживает **более 50 форматов файлов** и может обрабатывать **многосотстраничные PDF** без загрузки всего файла в память, сокращая использование ОЗУ до **70 %** по сравнению с наивными подходами. Его поисковый движок возвращает точные смещения, позволяя создавать пользовательские UI‑выделения или экспортировать результаты в другие системы. Библиотека активно поддерживается, совместима с Java 8+, и предлагает артефакты для Maven и Gradle для простой интеграции.
+
+## Требования
+
+Перед тем как приступить, убедитесь, что у вас есть всё необходимое:
+
+- **Java Development Environment**: установлен JDK 8+.
+- **Maven или Gradle**: для управления зависимостями и настройки проекта.
+- **GroupDocs.Parser for Java library**: скачайте или добавьте через зависимость.
+- **Пример документа**: тестовые PDF или тексты для поиска.
+- **Базовые знания Java**: знакомство с классами, методами и работой с файлами.
+
+Если у вас ещё нет библиотеки, вы можете получить последнюю версию с [GroupDocs Downloads](https://releases.groupdocs.com/parser/java/) или добавить её через Maven:
+
+```xml
+
+ com.groupdocs
+ groupdocs-parser
+ 21.12
+
+```
+
+## Импорт пакетов
+
+Для начала импортируем необходимые классы из GroupDocs.Parser:
+
+`Parser` — основной класс, используемый для загрузки и взаимодействия с документами. `HighlightOptions` настраивает, как будет выделяться найденный текст. `SearchOptions` определяет поведение поиска, например чувствительность к регистру. `SearchResult` представляет отдельное совпадение, найденное в документе.
+
+```java
+import com.groupdocs.parser.Parser;
+import com.groupdocs.parser.search.HighlightOptions;
+import com.groupdocs.parser.search.SearchOptions;
+import com.groupdocs.parser.search.SearchResult;
+```
+
+Эти импорты покрывают основные функции парсинга документов, настройки параметров выделения и выполнения поисковых операций.
+
+## Как работает процесс поиска и выделения?
+
+Загрузите ваш PDF, настройте объект `HighlightOptions`, выполните `parser.search`, а затем пройдитесь по коллекции `SearchResult`, чтобы собрать выделенные фрагменты. Весь процесс происходит в два шага: сначала парсер считывает структуру документа; затем поисковый движок сканирует текстовый поток, применяя заданные параметры. Такой подход обеспечивает высокую производительность даже для больших файлов.
+
+## Пошаговое руководство по поиску текста с выделением
+
+Рассмотрим процесс, разбитый на понятные шаги. Каждый шаг сопровождается объяснением, чтобы вы понимали, почему и как он работает.
+
+### Шаг 1: Инициализировать Parser с вашим документом
+
+**Что происходит здесь?**
+Создание экземпляра класса `Parser`, привязанного к вашему файлу документа, позволяет получить доступ к его содержимому и проанализировать его.
+
+`Parser` загружает документ и предоставляет методы для извлечения текста и поиска.
+
+```java
+try (Parser parser = new Parser("path/to/your/document.pdf")) {
+ // your code here
+}
+```
+
+**На самом деле:**
+Инструкция `try-with-resources` гарантирует, что ваш файл будет корректно закрыт после обработки, предотвращая утечки ресурсов. Замените `"path/to/your/document.pdf"` на точный путь к вашему файлу или URL.
+
+### Шаг 2: Настроить параметры выделения
+
+**Зачем определять параметры выделения?**
+Возможно, вы хотите контролировать внешний вид или поведение выделения найденных совпадений — например, количество символов вокруг совпадения или цвет (если поддерживается).
+
+В этом примере мы задаём радиус выделения в 15 символов:
+
+`HighlightOptions` указывает радиус контекста и визуальные настройки для выделенных поисковых совпадений.
+
+```java
+HighlightOptions highlightOptions = new HighlightOptions(15);
+```
+
+Это оборачивает найденный текст окружающим контекстом — как лупа вокруг ваших ключевых слов — делая проще увидеть, где находятся совпадения.
+
+### Шаг 3: Выполнить поиск в документе
+
+**Как работает поиск?**
+С помощью `parser.search` вы указываете ключевое слово или фразу, параметры поиска, а затем получаете итерируемую коллекцию объектов `SearchResult`.
+
+`SearchOptions` настраивает параметры поиска, такие как чувствительность к регистру. `SearchResult` содержит детали каждого совпадения, включая найденный текст и его расположение.
+
+```java
+Iterable results = parser.search("lorem", new SearchOptions(true, false, false, highlightOptions));
+```
+
+Разбор конструктора `SearchOptions`:
+
+- `true`: включить нечувствительный к регистру поиск.
+- `false`: не ограничиваться только полными словами.
+- `false`: не использовать регулярные выражения.
+- `highlightOptions`: передать нашу конфигурацию выделения.
+
+Эта настройка ищет все вхождения `"lorem"`, игнорируя регистр, и возвращает выделенные фрагменты.
+
+### Шаг 4: Обработать поддержку поиска и результаты
+
+**Проверить, поддерживается ли поиск**
+Некоторые форматы могут не поддерживать поиск — всегда проверяйте:
+
+`parser.isSearchSupported()` возвращает булево значение, указывающее, позволяет ли формат загруженного документа выполнять текстовый поиск.
+
+```java
+if (results == null) {
+ System.out.println("Search isn't supported in this document format.");
+ return;
+}
+```
+
+**Обработать каждое найденное совпадение**
+Пройдитесь по результатам, чтобы извлечь и отобразить совпадающие фрагменты с выделением:
+
+`SearchResult` предоставляет доступ к найденной фразе и её окружающему контексту.
+
+```java
+for (SearchResult result : results) {
+ String snippet = String.format("%s%s%s",
+ result.getLeftHighlightItem().getText(),
+ result.getText(),
+ result.getRightHighlightItem().getText());
+ System.out.println(snippet);
+}
+```
+
+## Распространённые проблемы и решения
+
+| Проблема | Причина | Решение |
+|----------|---------|---------|
+| **No results returned** | Формат документа не поддерживает поиск | Убедитесь, что `parser.isSearchSupported()` возвращает `true`. |
+| **Highlight radius seems too small** | Радиус по умолчанию равен 10 символам | Увеличьте радиус в `HighlightOptions` (например, `new HighlightOptions(20)`). |
+| **Out‑of‑memory error on large PDFs** | Весь файл загружается в память | Используйте `Parser` в режиме потоковой передачи или обрабатывайте файл частями; GroupDocs.Parser уже эффективно стримит большие файлы. |
+| **Case‑sensitivity not behaving as expected** | Неправильно установлен флаг `caseSensitive` | Убедитесь, что `SearchOptions(true, …)` задаёт корректное значение для нечувствительности к регистру. |
+
+## Часто задаваемые вопросы
+
+**Q: Могу ли я искать несколько ключевых слов одновременно?**
+A: Не напрямую; перебирайте каждое ключевое слово отдельно или сформируйте регулярное выражение, которое охватывает все нужные термины.
+
+**Q: Влияет ли радиус выделения на все форматы документов?**
+A: Для большинства поддерживаемых форматов радиус работает одинаково; некоторые форматы на основе изображений игнорируют его, поскольку у них нет собственного текстового слоя.
+
+**Q: Могу ли я изменить цвета выделения?**
+A: `HighlightOptions` управляет радиусом контекста; визуальные цвета зависят от просмотрщика PDF, а не от самого парсера.
+
+**Q: Поиск чувствителен к регистру по умолчанию?**
+A: Нет. Установив `caseSensitive` в `false` в `SearchOptions`, вы делаете поиск нечувствительным к регистру.
+
+**Q: Работает ли это со сканированными изображениями или только с текстовыми файлами?**
+A: Поиск работает только с текстовыми документами. Для сканированных изображений требуется OCR, который предоставляется отдельным модулем GroupDocs OCR.

+# Как использовать регулярные выражения для поиска текста в EPUB с GroupDocs.Parser
+
+В этом практическом руководстве вы узнаете **как использовать regex** для поиска текста внутри EPUB‑файлов с помощью GroupDocs.Parser для Java. Независимо от того, создаёте ли вы индексатор цифровой библиотеки или вам нужно находить конкретные фразы в тысячах электронных книг, освоение поиска с помощью регулярных выражений сэкономит ваше время и повысит точность. Мы пройдём настройку, ключевые классы и практические шаблоны, одновременно рассматривая **как эффективно искать epub** файлы.
+
+## Быстрые ответы
+- **Какая библиотека парсит EPUB в Java?** GroupDocs.Parser for Java.
+- **Можно ли использовать regex для поиска в EPUB?** Yes – the API accepts Java Pattern objects.
+- **Как выполнить поиск с учётом регистра?** Set `SearchOptions.setIgnoreCase(false)`.
+- **Нужна ли лицензия?** A free trial works for testing; a full license removes limits.
+- **Какая версия Java требуется?** JDK 8 or higher.
+
+## Что такое GroupDocs.Parser?
+GroupDocs.Parser — это Java‑библиотека, которая извлекает текст, изображения и метаданные из более чем 50 форматов документов, включая EPUB. Она предоставляет высокоуровневый класс `Parser`, который абстрагирует работу с файлами, позволяя сосредоточиться на логике поиска, а не на низкоуровневом разборе. Библиотека эффективно потоково обрабатывает контент, поддерживает среды с ограниченной памятью и предлагает встроенные возможности поиска, работающие непосредственно с разобранным текстом.
+
+## Почему использовать Regex с GroupDocs.Parser для EPUB?
+- **Широкая поддержка форматов:** Обрабатывает более 50 входных форматов, включая EPUB, без внешних конвертеров.
+- **Эффективная по памяти обработка:** Потоково обрабатывает контент, позволяя искать в EPUB‑файлах с сотнями страниц без загрузки всего файла в ОЗУ.
+- **Точное сопоставление шаблонов:** Regex позволяет находить отдельные слова, фразы или сложные шаблоны (например, даты, ISBN) одним вызовом.
+
+## Предварительные требования
+- **Java Development Kit (JDK) 8+** установлен и настроен в вашей IDE или системе сборки.
+- **GroupDocs.Parser for Java** библиотека (доступна через Maven или прямую загрузку).
+- Базовое знакомство с синтаксисом Java и концепциями регулярных выражений.
+
+## Как использовать Regex для поиска текста в EPUB‑файлах?
+Загрузите ваш EPUB с помощью `new Parser("book.epub")` и вызовите `search`, используя скомпилированный `Pattern`. Такой двухшаговый подход отделяет загрузку файла от выполнения шаблона, обеспечивая оптимальную производительность даже при работе с большими коллекциями.
+
+### Шаг 1: Инициализация Parser
+Класс `Parser` является точкой входа для загрузки и обработки EPUB‑файла.
+```java
+// ```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/parser/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5
+
+
+```
+```
+
+### Шаг 2: Создание Regex‑шаблона
+Класс `Pattern` в Java компилирует регулярное выражение. Например, чтобы найти любое слово, начинающееся с «list» после пробельного символа, используйте `\\slist\\w*`.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+// Initialize Parser object with an EPUB file path
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.epub")) {
+ // Your code here
+}
+```
+```
+
+### Шаг 3: Настройка параметров поиска
+`SearchOptions` настраивает работу поиска, например, чувствительность к регистру и нечеткое сопоставление.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+String epubFilePath = "YOUR_DOCUMENT_DIRECTORY/sample.epub";
+
+try (Parser parser = new Parser(epubFilePath)) {
+ // Further processing steps go here
+}
+```
+```
+
+### Шаг 4: Выполнение поиска
+`SearchResult` представляет собой отдельное совпадение, включая текст, номер страницы и смещения символов.
+```java
+// ```java
+String regexPattern = \\slist; // Matches any word preceded by whitespace and 'list'
+```
+```
+
+### Шаг 5: Обработка результатов
+Итерируйте коллекцию `SearchResult`, чтобы записывать совпадения, сохранять их в базе данных или запускать последующие процессы, такие как индексация или оповещение.
+```java
+// ```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options for search
+SearchOptions options = new SearchOptions(true /* case match */, false /* whole word */, true /* fuzzy */);
+```
+```
+
+## Как выполнить поиск с учётом регистра в Java?
+Установите `SearchOptions.setIgnoreCase(false)`, чтобы обеспечить точное совпадение с учётом регистра. Это важно при поиске идентификаторов, фрагментов кода или брендов, которым необходимо сохранять оригинальный регистр.
+
+## Распространённые сценарии использования
+1. **Индексация цифровой библиотеки:** Автоматически генерировать поисковые индексы для тысяч названий EPUB.
+2. **Курирование контента:** Находить тематические разделы (например, «Глава 5») в нескольких книгах для исследований.
+3. **Анализ данных:** Извлекать структурированные сущности, такие как ISBN, даты или имена авторов, используя специализированные regex‑шаблоны.
+4. **Интеграция в e‑learning:** Улучшать учебные платформы мгновенным полнотекстовым поиском по материалам курсов в PDF и EPUB.
+
+## Советы по производительности
+- **Оптимизировать regex‑шаблоны:** Предпочитайте простые классы символов вместо тяжёлых конструкций с обратным трекингом, чтобы снизить нагрузку на CPU.
+- **Разбивать большие EPUB‑файлы:** Обрабатывайте главы по отдельности, если файл превышает 200 МБ, чтобы избежать всплесков памяти.
+- **Кешировать часто используемые запросы:** Сохраняйте результаты популярных шаблонов (например, часто встречающихся ключевых слов) в лёгкой карте в памяти.
+
+## Часто задаваемые вопросы
+
+**Q: В чём разница между `search` и `extractText`?**
+A: `search` применяет regex‑шаблон и возвращает только совпадающие фрагменты, тогда как `extractText` возвращает всё содержимое документа без фильтрации.
+
+**Q: Можно ли искать по нескольким EPUB‑файлам за один вызов?**
+A: Один вызов API не обрабатывает пакет, но вы можете перебрать список файлов, повторно используя один и тот же `Pattern` и `SearchOptions` для каждого файла.
+
+**Q: Как работает нечеткий поиск?**
+A: Включите нечеткий режим в `SearchOptions`, чтобы разрешить расстояние Левенштейна до двух правок, что захватывает опечатки и небольшие вариации.
+
+**Q: Есть ли ограничение на размер документа?**
+A: GroupDocs.Parser может обрабатывать EPUB‑файлы до 500 МБ; более крупные файлы следует разбивать или потоково обрабатывать вручную.
+
+**Q: Нужна ли лицензия для разработки?**
+A: Бесплатная пробная версия предоставляет полный доступ к API с водяным знаком использования; постоянная лицензия снимает ограничения и предоставляет коммерческие права.

+- **Какую производительность можно ожидать?** GroupDocs.Parser обрабатывает HTML‑файлы объёмом 500 страниц менее чем за 2 секунды на типичном сервере.
+
+## Что такое «how to search html» с помощью regex?
+**“How to search html”** относится к использованию регулярных выражений для поиска текстовых шаблонов внутри HTML‑разметки. Эта техника позволяет точно находить слова, числа или пользовательские теги без парсинга всего дерева DOM. Применяя regex непосредственно к исходному HTML, разработчики могут быстро извлекать конкретные данные, проверять контент или фильтровать секции, делая это лёгкой альтернативой полному парсингу DOM.
+
+## Почему использовать GroupDocs.Parser для Java для regex‑поисков?
+GroupDocs.Parser поддерживает **70+** форматов ввода и вывода — включая HTML, DOCX, XLSX и PDF — при обработке многосотстраничных документов без загрузки всего файла в память. Его встроенный класс `SearchOptions` позволяет включать регулярные выражения, управлять чувствительностью к регистру и ограничивать результаты, обеспечивая быстрые и экономные по памяти сканирования.
+
+## Предварительные требования
+1. **GroupDocs.Parser for Java** (последняя версия, например 25.5 или новее).
+2. **Java Development Kit** 8 или новее, установленный и настроенный в вашей IDE.
+3. Базовое знакомство с **Java regex syntax** (например `\d+`, `\bSub\w*`).
+
+## Настройка GroupDocs.Parser для Java
+Для начала добавьте зависимость Maven в ваш `pom.xml`:
+
+```xml
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5
+
+```
+
+Для прямой загрузки посетите [GroupDocs.Parser for Java releases](https://releases.groupdocs.com/parser/java/) чтобы получить последнюю версию.
+
+**Получение лицензии**
+- **Free Trial** – изучайте основные функции бесплатно.
+- **Temporary License** – запросите расширенный тестовый ключ на [GroupDocs' website](https://purchase.groupdocs.com/temporary-license/).
+- **Purchase** – получите полную лицензию для неограниченного использования в продакшн.
+
+**Инициализация**
+После добавления библиотеки инициализируйте ваше Java‑приложение для использования GroupDocs.Parser:
+
+```java
+import com.groupdocs.parser.Parser;
+
+public class SetupExample {
+ public static void main(String[] args) {
+ String filePath = "path/to/your/document.html";
+ try (Parser parser = new Parser(filePath)) {
+ // Initialization complete, ready to parse and search!
+ } catch (Exception e) {
+ e.printStackTrace();
+ }
+ }
+}
+```
+
+## Как искать HTML с помощью GroupDocs.Parser для Java?
+Загрузите ваш HTML‑файл с помощью класса `Parser` и выполните поиск regex всего в две строки кода. Класс `Parser` является точкой входа, который читает и парсит поддерживаемые типы документов, предоставляя методы для извлечения текста и поиска. Настраивая `SearchOptions`, вы указываете парсеру рассматривать ваш шаблон как регулярное выражение, при необходимости включая чувствительность к регистру или поиск целых слов.
+
+### Пошаговая реализация
+
+### Шаг 1: Определите ваш шаблон регулярного выражения
+Сначала составьте шаблон regex, который соответствует нужному вам тексту. В этом примере мы ищем слова, начинающиеся с **“Sub”** и за которыми следует цифра (например, `Sub1`, `Sub9`).
+
+```java
+String regexPattern = "Sub[0-9]";
+```
+
+### Шаг 2: Настройте параметры поиска
+`SearchOptions` — это объект конфигурации, который задаёт поведение поиска, такое как режим regex и чувствительность к регистру.
+Настройте объект `SearchOptions`, чтобы активировать режим regex, установить чувствительность к регистру и решить, искать только целые слова. `SearchOptions` является держателем конфигурации, который указывает парсеру, как выполнять поиск.
+
+```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options: case-sensitive, whole word, use regex
+SearchOptions options = new SearchOptions(true, false, true);
+```
+
+### Шаг 3: Выполните поиск
+Вызовите метод `search` у экземпляра `Parser`, передав путь к HTML‑файлу, шаблон и параметры. Метод возвращает коллекцию объектов `SearchResult`, каждый из которых содержит найденный текст и его расположение в документе.
+
+```java
+import com.groupdocs.parser.data.SearchResult;
+
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.html")) {
+ Iterable results = parser.search(regexPattern, options);
+
+ for (SearchResult result : results) {
+ System.out.println(String.format("At %d: %s", result.getPosition(), result.getText()));
+ }
+} catch (Exception e) {
+ e.printStackTrace();
+}
+```
+
+**Ключевые параметры конфигурации**
+- **Case Sensitivity** – установите `true` для точного совпадения регистра.
+- **Whole Word Search** – `false` включает частичные совпадения.
+- **Use Regular Expressions** – должно быть `true`, чтобы включить обработку regex.
+
+## Распространённые проблемы и решения
+- **Incorrect file path** – проверьте, что HTML‑файл доступен из рабочей директории вашего приложения.
+- **Invalid regex syntax** – протестируйте ваш шаблон с помощью онлайн‑тестера regex перед тем, как внедрять его в код.
+- **Memory leaks** – всегда закрывайте экземпляр `Parser` или используйте try‑with‑resources, чтобы гарантировать освобождение потоков.
+
+## Практические применения
+Использование поисков на основе regex в HTML открывает возможности для множества реальных сценариев:
+1. **Data Extraction** – извлекать номера счетов, идентификаторы или метки времени из массовых HTML‑отчётов.
+2. **Content Filtering** – автоматически удалять или помечать секции, содержащие запрещённые ключевые слова.
+3. **Log Analysis** – сканировать логи в формате HTML на предмет шаблонов ошибок или метрик производительности.
+4. **ETL Pipelines** – интегрировать парсер в процессы загрузки данных, которые нормализуют контент, полученный веб‑скрейпингом.
+
+## Соображения по производительности
+При работе с большими корпусами HTML учитывайте следующие рекомендации:
+- **Optimize regex patterns** – избегайте избыточного отката; при возможности используйте атомарные группы или жадные квантификаторы.
+- **Streamline memory usage** – оберните парсинг в блок try‑with‑resources, чтобы JVM быстро освобождала буферы.
+- **Parallel processing** – используйте `ForkJoinPool` Java для одновременного поиска в нескольких документах, масштабируя линейно на многопроцессорных серверах.
+
+## Часто задаваемые вопросы
+
+**Q: Что такое регулярное выражение?**
+A: Регулярное выражение (regex) — это лаконичный язык, основанный на шаблонах, для сопоставления последовательностей символов в строках, широко используемый для валидации, поиска и манипуляций с текстом.
+
+**Q: Может ли GroupDocs.Parser работать с файлами, не являющимися HTML?**
+A: Да, он поддерживает более 70 форматов — включая PDF, DOCX, XLSX и PPTX — поэтому та же логика поиска работает с различными типами документов.
+
+**Q: Как следует обрабатывать ошибки парсинга?**
+A: Оберните код парсинга в блок try‑catch, ловя `ParserException`, чтобы записать проблему в журнал и гарантировать закрытие ресурсов.
+
+**Q: Мой regex не возвращает результатов — в чём проблема?**
+A: Проверьте шаблон на наличие экранированных символов, убедитесь в правильных настройках чувствительности к регистру и подтвердите, что целевой текст действительно присутствует в исходном HTML.
+
+**Q: Есть ли ограничение по размеру HTML‑файлов?**
+A: GroupDocs.Parser может обрабатывать файлы размером до 2 ГБ; для чрезвычайно больших HTML‑файлов рассмотрите их разбиение или потоковую обработку секций, чтобы оставаться в пределах ограничений памяти.
+
+## Заключение
+Следуя этому руководству, вы теперь знаете **how to search html** документы, используя мощный движок regex, встроенный в GroupDocs.Parser для Java. Вы можете быстро находить шаблоны, извлекать значимые данные и интегрировать решение в более крупные Java‑приложения или конвейеры данных.
+
+**Следующие шаги:** экспериментировать с более сложными шаблонами, комбинировать несколько `SearchOptions` или внедрить парсер в микросервис Spring Boot для извлечения текста по запросу.

+- questions:
+ - answer: Not directly; iterate over each keyword or construct a regex pattern that

+ question: Can I search multiple keywords at once?
+ - answer: For most supported formats the radius works uniformly; some image‑based
+ formats ignore it because they lack native text layers.
+ question: Does the highlight radius affect all document formats?
+ - answer: '`HighlightOptions` controls context radius; visual colors depend on the
+ viewer you use to render the PDF, not the parser itself.'
+ question: Can I change highlight colors?
+ - answer: No. By setting `caseSensitive` to `false` in `SearchOptions`, the search
+ becomes case‑insensitive.
+ question: Is search case‑sensitive by default?
+ - answer: Search works on text‑based documents. For scanned images you need OCR
+ capabilities, which GroupDocs OCR provides as a separate module.

+¿Alguna vez te has sentido abrumado por una gran cantidad de documentos—PDF, archivos Word u otros formatos—y deseas encontrar palabras o frases específicas sin esfuerzo? **El procesamiento de PDF en Java** lo hace posible. En esta guía aprenderás a buscar texto dentro de PDFs y generar fragmentos resaltados usando **GroupDocs.Parser para Java**. Ya sea que estés construyendo una herramienta de análisis de documentos o automatizando la revisión de contenido, los pasos a continuación te ofrecen una solución clara y lista para producción.
+
+## Respuestas rápidas
+- **¿Qué biblioteca maneja la búsqueda de texto en PDF en Java?** GroupDocs.Parser para Java.
+- **¿Necesito una licencia para desarrollo?** Una licencia temporal funciona para pruebas; se requiere una licencia completa para producción.
+- **¿Puedo resaltar múltiples ocurrencias a la vez?** Sí—establece un radio de resaltado e itera sobre los resultados.
+- **¿La búsqueda distingue entre mayúsculas y minúsculas?** Por defecto no distingue; puedes cambiarlo mediante `SearchOptions`.
+- **¿Qué formatos son compatibles?** Más de 50 formatos de entrada y salida, incluidos PDF, DOCX, XLSX, PPTX, HTML e imágenes.
+
+## ¿Qué es el procesamiento de PDF en Java?
+`Java PDF processing` es el conjunto de operaciones programáticas—como extraer, buscar y resaltar texto—realizadas sobre archivos PDF usando bibliotecas Java. Con GroupDocs.Parser puedes buscar en cualquier documento compatible, obtener el contexto circundante y aplicar resaltados visuales, todo sin abrir el archivo en un visor. Esta capacidad te permite crear archivos archivísticos rápidos y buscables, y pipelines de revisión automatizados que escalan a miles de páginas por documento.
+
+## ¿Por qué usar GroupDocs.Parser para el procesamiento de PDF en Java?
+GroupDocs.Parser admite **más de 50 formatos de archivo** y puede procesar **PDFs de cientos de páginas** sin cargar todo el archivo en memoria, reduciendo el uso de RAM hasta en **un 70 %** comparado con enfoques ingenuos. Su motor de búsqueda devuelve desplazamientos precisos, lo que te permite crear resaltados personalizados en la UI o exportar resultados a otros sistemas. La biblioteca se mantiene activamente, es compatible con Java 8+ y ofrece artefactos tanto para Maven como para Gradle, facilitando la integración.
+
+## Requisitos previos
+
+Antes de arremangarnos, asegúrate de tener lo esencial listo:
+
+- **Entorno de desarrollo Java**: JDK 8+ instalado.
+- **Maven o Gradle**: Para la gestión de dependencias y la configuración del proyecto.
+- **Biblioteca GroupDocs.Parser para Java**: Descárgala o añádela mediante dependencia.
+- **Un documento de muestra**: PDFs o textos de prueba para buscar dentro.
+- **Conocimientos básicos de Java**: Familiaridad con clases, métodos y manejo de archivos.
+
+Si aún no tienes la biblioteca, puedes obtener la última versión en [GroupDocs Downloads](https://releases.groupdocs.com/parser/java/) o agregarla mediante Maven:
+
+```xml
+
+ com.groupdocs
+ groupdocs-parser
+ 21.12
+
+```
+
+## Importar paquetes
+
+Para comenzar, importemos las clases esenciales de GroupDocs.Parser:
+
+`Parser` es la clase principal utilizada para cargar e interactuar con documentos. `HighlightOptions` configura cómo se resaltará el texto coincidente. `SearchOptions` define el comportamiento de búsqueda, como la sensibilidad a mayúsculas. `SearchResult` representa una coincidencia individual encontrada en el documento.
+
+```java
+import com.groupdocs.parser.Parser;
+import com.groupdocs.parser.search.HighlightOptions;
+import com.groupdocs.parser.search.SearchOptions;
+import com.groupdocs.parser.search.SearchResult;
+```
+
+Estas importaciones cubren las funcionalidades centrales para analizar documentos, establecer opciones de resaltado y ejecutar operaciones de búsqueda.
+
+## ¿Cómo funciona el flujo de trabajo de búsqueda y resaltado?
+
+Carga tu PDF, configura un objeto `HighlightOptions`, ejecuta `parser.search` y luego itera sobre la colección `SearchResult` para construir fragmentos resaltados. El proceso completo se ejecuta en dos pasos: primero, el parser lee la estructura del documento; segundo, el motor de búsqueda escanea el flujo de texto aplicando las opciones que definiste. Este enfoque garantiza alto rendimiento incluso en archivos grandes.
+
+## Guía paso a paso para buscar texto con resaltados
+
+Recorramos el proceso subdividido en pasos manejables y claros. Cada paso tiene su propia explicación para ayudarte a comprender el porqué y el cómo.
+
+### Paso 1: Inicializar el Parser con tu documento
+
+**¿Qué ocurre aquí?**
+Crear una instancia de la clase `Parser` vinculada a tu archivo de documento te permite acceder y analizar su contenido.
+
+`Parser` carga un documento y proporciona métodos para la extracción de texto y la búsqueda.
+
+```java
+try (Parser parser = new Parser("path/to/your/document.pdf")) {
+ // your code here
+}
+```
+
+**En la práctica:**
+La instrucción `try-with-resources` garantiza que tu archivo se cierre correctamente después del procesamiento, evitando fugas de recursos. Reemplaza `"path/to/your/document.pdf"` con la ruta o URL exacta de tu archivo.
+
+### Paso 2: Configurar opciones de resaltado
+
+**¿Por qué definir opciones de resaltado?**
+Puede que quieras controlar la apariencia o el comportamiento de cómo se resaltan los resultados de búsqueda—por ejemplo, la cantidad de caracteres que se muestran alrededor de la coincidencia o el color (si es compatible).
+
+En este ejemplo, establecemos un radio de resaltado de 15 caracteres:
+
+`HighlightOptions` especifica el radio de contexto y la configuración visual para los resultados de búsqueda resaltados.
+
+```java
+HighlightOptions highlightOptions = new HighlightOptions(15);
+```
+
+Esto envuelve el texto encontrado con el contexto circundante—como una lupa alrededor de tus palabras clave—facilitando la identificación de dónde ocurren las coincidencias.
+
+### Paso 3: Ejecutar la búsqueda en el documento
+
+**¿Cómo funciona la búsqueda?**
+Usando `parser.search`, especificas la palabra clave o frase, las opciones de búsqueda y luego obtienes una colección iterable de objetos `SearchResult`.
+
+`SearchOptions` configura parámetros de búsqueda como la sensibilidad a mayúsculas. `SearchResult` contiene los detalles de cada coincidencia, incluido el texto coincidente y su ubicación.
+
+```java
+Iterable results = parser.search("lorem", new SearchOptions(true, false, false, highlightOptions));
+```
+
+Desglose del constructor `SearchOptions`:
+
+- `true`: Habilita la búsqueda sin distinción de mayúsculas y minúsculas.
+- `false`: No limitar a coincidencias de palabras completas.
+- `false`: No buscar patrones regex.
+- `highlightOptions`: Pasa nuestra configuración de resaltado.
+
+Esta configuración busca todas las ocurrencias de `"lorem"` ignorando mayúsculas y con fragmentos resaltados.
+
+### Paso 4: Manejar el soporte de búsqueda y los resultados
+
+**Verificar si la búsqueda es compatible**
+Algunos formatos pueden no soportar búsqueda—siempre confirma:
+
+`parser.isSearchSupported()` devuelve un booleano que indica si el formato del documento cargado permite la búsqueda de texto.
+
+```java
+if (results == null) {
+ System.out.println("Search isn't supported in this document format.");
+ return;
+}
+```
+
+**Procesar cada coincidencia**
+Recorre los resultados para extraer y mostrar fragmentos coincidentes con resaltados:
+
+Los objetos `SearchResult` dan acceso a la frase encontrada y su contexto circundante.
+
+```java
+for (SearchResult result : results) {
+ String snippet = String.format("%s%s%s",
+ result.getLeftHighlightItem().getText(),
+ result.getText(),
+ result.getRightHighlightItem().getText());
+ System.out.println(snippet);
+}
+```
+
+## Problemas comunes y soluciones
+
+| Problema | Razón | Solución |
+|----------|-------|----------|
+| **No se devuelven resultados** | Formato del documento no buscable | Verifica que `parser.isSearchSupported()` devuelva `true`. |
+| **El radio de resaltado parece demasiado pequeño** | El radio predeterminado es de 10 caracteres | Aumenta el radio en `HighlightOptions` (p. ej., `new HighlightOptions(20)`). |
+| **Error de falta de memoria en PDFs grandes** | El archivo completo se carga en memoria | Usa `Parser` en modo streaming o procesa el archivo por fragmentos; GroupDocs.Parser ya transmite archivos grandes de forma eficiente. |
+| **La sensibilidad a mayúsculas no funciona como se espera** | Bandera `caseSensitive` mal configurada | Asegúrate de que `SearchOptions(true, …)` establezca el booleano correcto para la insensibilidad a mayúsculas. |
+
+## Preguntas frecuentes
+
+**P: ¿Puedo buscar múltiples palabras clave a la vez?**
+R: No directamente; itera sobre cada palabra clave o construye un patrón regex que coincida con todos los términos deseados.
+
+**P: ¿El radio de resaltado afecta a todos los formatos de documento?**
+R: Para la mayoría de los formatos compatibles el radio funciona de manera uniforme; algunos formatos basados en imágenes lo ignoran porque carecen de capas de texto nativas.
+
+**P: ¿Puedo cambiar los colores de resaltado?**
+R: `HighlightOptions` controla el radio de contexto; los colores visuales dependen del visor que uses para renderizar el PDF, no del parser en sí.
+
+**P: ¿La búsqueda distingue entre mayúsculas y minúsculas por defecto?**
+R: No. Al establecer `caseSensitive` a `false` en `SearchOptions`, la búsqueda se vuelve insensible a mayúsculas.
+
+**P: ¿Esto funciona con imágenes escaneadas o solo con archivos basados en texto?**
+R: La búsqueda funciona en documentos basados en texto. Para imágenes escaneadas necesitas capacidades OCR, que GroupDocs OCR ofrece como módulo separado.

Recorreremos la configuración, las clases clave y patrones prácticos, todo mientras cubrimos **cómo buscar epub** de manera eficiente.
+
+## Respuestas rápidas
+- **¿Qué biblioteca analiza EPUB en Java?** GroupDocs.Parser for Java.
+- **¿Puedo usar regex para buscar en EPUB?** Sí – la API acepta objetos Java Pattern.
+- **¿Cómo realizar una búsqueda sensible a mayúsculas/minúsculas?** Set `SearchOptions.setIgnoreCase(false)`.
+- **¿Necesito una licencia?** Una prueba gratuita funciona para pruebas; una licencia completa elimina los límites.
+- **¿Qué versión de Java se requiere?** JDK 8 o superior.
+
+## Qué es GroupDocs.Parser?
+GroupDocs.Parser es una biblioteca Java que extrae texto, imágenes y metadatos de más de 50 formatos de documentos, incluido EPUB. Proporciona una clase de alto nivel `Parser` que abstrae el manejo de archivos, permitiéndote centrarte en la lógica de búsqueda en lugar del análisis de bajo nivel. La biblioteca transmite el contenido de manera eficiente, soporta entornos con memoria limitada y ofrece capacidades de búsqueda integradas que funcionan directamente sobre el texto analizado.
+
+## Por qué usar Regex con GroupDocs.Parser para EPUB?
+- **Amplio soporte de formatos:** Maneja más de 50 formatos de entrada, incluido EPUB, sin conversores externos.
+- **Procesamiento eficiente en memoria:** Transmite el contenido, permitiendo buscar EPUBs de cientos de páginas sin cargar todo el archivo en RAM.
+- **Coincidencia de patrones precisa:** Regex te permite localizar palabras completas, frases o patrones complejos (p. ej., fechas, ISBN) en una sola llamada.
+
+## Requisitos previos
+- **Java Development Kit (JDK) 8+** instalado y configurado en tu IDE o herramienta de compilación.
+- **GroupDocs.Parser for Java** biblioteca (disponible vía Maven o descarga directa).
+- Familiaridad básica con la sintaxis de Java y los conceptos de expresiones regulares.
+
+## Cómo usar Regex para buscar texto en archivos EPUB?
+Carga tu EPUB con `new Parser("book.epub")` y llama a `search` usando un `Pattern` compilado. Este enfoque de dos pasos aísla la carga del archivo de la ejecución del patrón, garantizando un rendimiento óptimo incluso en colecciones grandes.
+
+### Paso 1: Inicializar el Parser
+La clase `Parser` es el punto de entrada para cargar y manejar un archivo EPUB.
+```java
+// ```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/parser/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5
+
+
+```
+```
+
+### Paso 2: Construir un patrón Regex
+La clase `Pattern` de Java compila la expresión regular. Por ejemplo, para encontrar cualquier palabra que comience con “list” después de un carácter de espacio, usa `\\slist\\w*`.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+// Initialize Parser object with an EPUB file path
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.epub")) {
+ // Your code here
+}
+```
+```
+
+### Paso 3: Configurar opciones de búsqueda
+`SearchOptions` configura cómo opera la búsqueda, como la sensibilidad a mayúsculas y coincidencia difusa.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+String epubFilePath = "YOUR_DOCUMENT_DIRECTORY/sample.epub";
+
+try (Parser parser = new Parser(epubFilePath)) {
+ // Further processing steps go here
+}
+```
+```
+
+### Paso 4: Ejecutar la búsqueda
+`SearchResult` representa una coincidencia única, incluyendo texto, número de página y desplazamientos de caracteres.
+```java
+// ```java
+String regexPattern = \\slist; // Matches any word preceded by whitespace and 'list'
+```
+```
+
+### Paso 5: Procesar los resultados
+Itera sobre la colección `SearchResult` para registrar coincidencias, almacenarlas en una base de datos o activar flujos de trabajo posteriores como indexación o alertas.
+```java
+// ```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options for search
+SearchOptions options = new SearchOptions(true /* case match */, false /* whole word */, true /* fuzzy */);
+```
+```
+
+## Cómo realizar una búsqueda sensible a mayúsculas en Java?
+Establece `SearchOptions.setIgnoreCase(false)` para aplicar coincidencia exacta de mayúsculas/minúsculas. Esto es esencial al buscar identificadores, fragmentos de código o nombres de marca que deben conservar su capitalización original.
+
+## Casos de uso comunes
+1. **Indexación de bibliotecas digitales:** Genera automáticamente índices buscables para miles de títulos EPUB.
+2. **Curación de contenido:** Localiza secciones temáticas (p. ej., “Capítulo 5”) en varios libros para investigación.
+3. **Minería de datos:** Extrae entidades estructuradas como ISBN, fechas o nombres de autores usando patrones regex a medida.
+4. **Integración de e‑learning:** Mejora las plataformas de cursos con capacidades de búsqueda instantánea de texto completo para materiales de curso en PDF y EPUB.
+
+## Consejos de rendimiento
+- **Optimizar patrones regex:** Prefiere clases de caracteres simples sobre construcciones que generen mucho retroceso para mantener bajo el uso de CPU.
+- **Dividir EPUBs grandes:** Procesa capítulos individualmente si el archivo supera los 200 MB para evitar picos de memoria.
+- **Cachear consultas frecuentes:** Almacena los resultados de patrones populares (p. ej., palabras clave comunes) en un mapa ligero en memoria.
+
+## Preguntas frecuentes
+
+**Q: ¿Cuál es la diferencia entre `search` y `extractText`?**
+A: `search` aplica un patrón regex y devuelve solo los fragmentos coincidentes, mientras que `extractText` devuelve todo el contenido del documento sin filtrar.
+
+**Q: ¿Puedo buscar en varios archivos EPUB en una sola llamada?**
+A: Ninguna llamada única de la API procesa un lote, pero puedes iterar sobre una lista de archivos, reutilizando el mismo `Pattern` y `SearchOptions` para cada archivo.
+
+**Q: ¿Cómo funciona la búsqueda difusa?**
+A: Habilita el modo difuso en `SearchOptions` para permitir una distancia de Levenshtein de hasta dos ediciones, lo que captura errores tipográficos y variaciones menores.
+
+**Q: ¿Existe un límite de tamaño de documento?**
+A: GroupDocs.Parser puede manejar EPUBs de hasta 500 MB; los archivos más grandes deben dividirse o transmitirse manualmente.
+
+**Q: ¿Necesito una licencia para desarrollo?**
+A: Una prueba gratuita brinda acceso completo a la API con una marca de agua de uso; una licencia permanente elimina restricciones y otorga derechos comerciales.

+ }
+}
+```
+
+## ¿Cómo buscar HTML usando GroupDocs.Parser para Java?
+Cargue su archivo HTML con la clase `Parser` y ejecute una búsqueda regex en solo dos líneas de código. La clase `Parser` es el punto de entrada que lee y analiza los tipos de documentos compatibles, exponiendo métodos para la extracción de texto y la búsqueda. Al configurar `SearchOptions`, indica al parser que trate su patrón como una expresión regular, opcionalmente habilitando la coincidencia sensible a mayúsculas o de palabra completa.
+
+### Implementación paso a paso
+
+### Paso 1: Defina su patrón de expresión regular
+Primero, cree el patrón regex que coincida con el texto que necesita. En este ejemplo buscamos palabras que comiencen con **“Sub”** seguido de un dígito (p. ej., `Sub1`, `Sub9`).
+
+```java
+String regexPattern = "Sub[0-9]";
+```
+
+### Paso 2: Configurar opciones de búsqueda
+`SearchOptions` es un objeto de configuración que especifica el comportamiento de búsqueda, como el modo regex y la sensibilidad a mayúsculas.
+Configure el objeto `SearchOptions` para activar el modo regex, establecer la sensibilidad a mayúsculas y decidir si solo coincidir palabras completas. `SearchOptions` es un contenedor de configuración que indica al parser cómo realizar la búsqueda.
+
+```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options: case-sensitive, whole word, use regex
+SearchOptions options = new SearchOptions(true, false, true);
+```
+
+### Paso 3: Ejecutar la búsqueda
+Invoca el método `search` en una instancia de `Parser`, pasando la ruta del archivo HTML, el patrón y las opciones. El método devuelve una colección de objetos `SearchResult`, cada uno con el texto coincidente y su ubicación en el documento.
+
+```java
+import com.groupdocs.parser.data.SearchResult;
+
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.html")) {
+ Iterable results = parser.search(regexPattern, options);
+
+ for (SearchResult result : results) {
+ System.out.println(String.format("At %d: %s", result.getPosition(), result.getText()));
+ }
+} catch (Exception e) {
+ e.printStackTrace();
+}
+```
+
+**Opciones de configuración clave**
+- **Sensibilidad a mayúsculas** – establezca `true` para coincidencias exactas de mayúsculas.
+- **Búsqueda de palabra completa** – `false` incluye coincidencias parciales.
+- **Usar expresiones regulares** – debe ser `true` para habilitar el procesamiento regex.
+
+## Problemas comunes y soluciones
+- **Ruta de archivo incorrecta** – verifique que el archivo HTML sea accesible desde el directorio de trabajo de su aplicación.
+- **Sintaxis regex inválida** – pruebe su patrón con un probador de regex en línea antes de incorporarlo al código.
+- **Fugas de memoria** – siempre cierre la instancia `Parser` o use try‑with‑resources para asegurar que los flujos se liberen.
+
+## Aplicaciones prácticas
+El uso de búsquedas impulsadas por regex en HTML abre puertas a muchos escenarios del mundo real:
+
+1. **Extracción de datos** – extraiga números de factura, IDs o marcas de tiempo de informes HTML masivos.
+2. **Filtrado de contenido** – elimine o marque automáticamente secciones que contengan palabras clave prohibidas.
+3. **Análisis de registros** – escanee registros con formato HTML en busca de patrones de error o métricas de rendimiento.
+4. **Pipelines ETL** – integre el parser en flujos de ingestión de datos que normalizan contenido extraído de la web.
+
+## Consideraciones de rendimiento
+Al manejar grandes corpora HTML, tenga en cuenta estos consejos:
+
+- **Optimizar patrones regex** – evite retrocesos excesivos; use grupos atómicos o cuantificadores posesivos cuando sea posible.
+- **Optimizar uso de memoria** – envuelva el análisis en un bloque try‑with‑resources para que la JVM recupere los búferes rápidamente.
+- **Procesamiento paralelo** – aproveche `ForkJoinPool` de Java para buscar varios documentos simultáneamente, escalando linealmente en servidores multinúcleo.
+
+## Preguntas frecuentes
+
+**Q: ¿Qué es una expresión regular?**
+A: Una expresión regular (regex) es un lenguaje conciso basado en patrones para coincidir secuencias de caracteres dentro de cadenas, ampliamente usado para validación, búsqueda y manipulación de texto.
+
+**Q: ¿Puede GroupDocs.Parser manejar archivos que no sean HTML?**
+A: Sí, admite más de 70 formatos—incluidos PDF, DOCX, XLSX y PPTX—por lo que la misma lógica de búsqueda funciona en diversos tipos de documentos.
+
+**Q: ¿Cómo debo manejar los errores de análisis?**
+A: Encierre el código de análisis en un bloque try‑catch, capturando `ParserException` para registrar el problema y asegurar que los recursos se cierren.
+
+**Q: Mi regex no devuelve resultados—¿qué está mal?**
+A: Verifique el patrón en busca de caracteres escapados, confirme la configuración de sensibilidad a mayúsculas y asegúrese de que el texto objetivo realmente exista en el origen HTML.
+
+**Q: ¿Existe un límite de tamaño para los archivos HTML?**
+A: GroupDocs.Parser puede procesar archivos de hasta 2 GB; para archivos HTML extremadamente grandes, considere dividirlos o transmitir secciones para mantenerse dentro de los límites de memoria.
+
+## Conclusión
+Al seguir esta guía ahora sabe **how to search html** documentos usando un potente motor regex incorporado en GroupDocs.Parser para Java. Puede localizar rápidamente patrones, extraer datos significativos e integrar la solución en aplicaciones Java más grandes o pipelines de datos.
+
+**Próximos pasos:** experimente con patrones más complejos, combine múltiples `SearchOptions` o incruste el parser en un microservicio Spring Boot para extracción de texto bajo demanda.

+# Java PDF Processing: Sök och markera med GroupDocs
+
+Har du någonsin känt dig överväldigad av en mängd dokument—PDF‑filer, Word‑filer eller andra format—och önskat att du enkelt kunde hitta specifika ord eller fraser? **Java PDF processing** gör det möjligt. I den här guiden lär du dig hur du söker text i PDF‑filer och genererar markerade utdrag med **GroupDocs.Parser for Java**. Oavsett om du bygger ett dokumentanalysverktyg eller automatiserar innehållsgranskning, ger stegen nedan en tydlig, produktionsklar lösning.
+
+## Snabba svar
+- **Vilket bibliotek hanterar PDF‑text sökning i Java?** GroupDocs.Parser for Java.
+- **Behöver jag en licens för utveckling?** En tillfällig licens fungerar för testning; en full licens krävs för produktion.
+- **Kan jag markera flera förekomster samtidigt?** Ja—sätt en markeringsradie och iterera över resultaten.
+- **Är sökningen skiftlägeskänslig?** Som standard är den skiftlägesokänslig; du kan växla den via `SearchOptions`.
+- **Vilka format stöds?** Över 50 in‑ och utdataformat, inklusive PDF, DOCX, XLSX, PPTX, HTML och bilder.
+
+## Vad är java pdf processing?
+`Java PDF processing` är en uppsättning programatiska operationer—såsom extrahering, sökning och markering av text—som utförs på PDF‑filer med Java‑bibliotek. Med GroupDocs.Parser kan du söka i alla stödda dokument, hämta omgivande kontext och applicera visuella markeringar, utan att öppna filen i en visare. Denna funktionalitet låter dig bygga snabba, sökbara arkiv och automatiserade granskningspipelines som kan hantera tusentals sidor per dokument.
+
+## Varför använda GroupDocs.Parser för java pdf processing?
+GroupDocs.Parser stöder **50+ filformat** och kan bearbeta **PDF‑filer med flera hundra sidor** utan att ladda hela filen i minnet, vilket minskar RAM‑användningen med upp till **70 %** jämfört med naiva metoder. Dess sökmotor returnerar exakta offset‑värden, vilket gör det möjligt att bygga anpassade UI‑markeringar eller exportera resultat till andra system. Biblioteket underhålls aktivt, är kompatibelt med Java 8+ och erbjuder både Maven‑ och Gradle‑artefakter för enkel integration.
+
+## Förutsättningar
+
+Innan vi sätter igång, se till att du har dessa grundläggande saker redo:
+
+- **Java Development Environment**: JDK 8+ installerat.
+- **Maven eller Gradle**: För beroendehantering och projektuppsättning.
+- **GroupDocs.Parser for Java‑biblioteket**: Ladda ner eller lägg till via beroende.
+- **Ett exempel‑dokument**: Test‑PDF‑filer eller texter att söka i.
+- **Grundläggande Java‑kunskaper**: Bekantskap med klasser, metoder och filhantering.
+
+Om du ännu inte har biblioteket kan du hämta den senaste från [GroupDocs Downloads](https://releases.groupdocs.com/parser/java/) eller lägga till det via Maven:
+
+```xml
+
+ com.groupdocs
+ groupdocs-parser
+ 21.12
+
+```
+
+## Importera paket
+
+För att börja, låt oss importera de nödvändiga klasserna från GroupDocs.Parser:
+
+`Parser` är huvudklassen som används för att ladda och interagera med dokument. `HighlightOptions` konfigurerar hur matchad text markeras. `SearchOptions` definierar sökbeteende såsom skiftlägeskänslighet. `SearchResult` representerar en enskild träff som hittats i dokumentet.
+
+```java
+import com.groupdocs.parser.Parser;
+import com.groupdocs.parser.search.HighlightOptions;
+import com.groupdocs.parser.search.SearchOptions;
+import com.groupdocs.parser.search.SearchResult;
+```
+
+Dessa importeringar täcker kärnfunktionaliteten för att parsra dokument, ställa in markeringsalternativ och utföra sökoperationer.
+
+## Hur fungerar arbetsflödet för sökning och markering?
+
+Läs in din PDF, konfigurera ett `HighlightOptions`‑objekt, kör `parser.search` och iterera sedan över `SearchResult`‑samlingen för att bygga markerade utdrag. hela processen körs i två steg: först läser parsern dokumentstrukturen; sedan skannar sökmotorn textströmmen och tillämpar de alternativ du definierat. Detta tillvägagångssätt säkerställer hög prestanda även för stora filer.
+
+## Steg‑för‑steg‑guide för att söka text med markeringar
+
+Låt oss gå igenom processen uppdelad i hanterbara, tydliga steg. Varje steg har sin egen förklaring för att hjälpa dig förstå varför och hur.
+
+### Steg 1: Initiera Parser med ditt dokument
+
+**Vad händer här?**
+Att skapa en instans av `Parser`‑klassen kopplad till din dokumentfil gör att du kan komma åt och analysera dess innehåll.
+
+`Parser` laddar ett dokument och tillhandahåller metoder för textutdragning och sökning.
+
+```java
+try (Parser parser = new Parser("path/to/your/document.pdf")) {
+ // your code here
+}
+```
+
+**I praktiken:**
+`try-with-resources`‑satsen säkerställer att din fil stängs korrekt efter bearbetning, vilket förhindrar resurssläpp. Ersätt `"path/to/your/document.pdf"` med din exakta filsökväg eller URL.
+
+### Steg 2: Ställ in markeringsalternativ
+
+**Varför definiera markeringsalternativ?**
+Du kanske vill kontrollera utseendet eller beteendet för hur sökträffar markeras—t.ex. antalet tecken som visas runt matchen eller färgen (om den stöds).
+
+I detta exempel sätter vi en markeringsradie på 15 tecken:
+
+`HighlightOptions` specificerar kontextradien och visuella inställningar för markerade sökträffar.
+
+```java
+HighlightOptions highlightOptions = new HighlightOptions(15);
+```
+
+Det här omsluter den hittade texten med omgivande kontext—som ett förstoringsglas runt dina nyckelord—vilket gör det enklare att se var träffarna finns.
+
+### Steg 3: Utför sökningen i dokumentet
+
+**Hur fungerar sökningen?**
+Med `parser.search` anger du nyckelordet eller frasen, sökalternativen och får sedan en itererbar samling av `SearchResult`‑objekt.
+
+`SearchOptions` konfigurerar sökparametrar såsom skiftlägeskänslighet. `SearchResult` innehåller detaljer för varje träff, inklusive den matchade texten och dess plats.
+
+```java
+Iterable results = parser.search("lorem", new SearchOptions(true, false, false, highlightOptions));
+```
+
+Genomgång av `SearchOptions`‑konstruktorn:
+
+- `true`: Aktivera skiftlägesokänslig sökning.
+- `false`: Matcha inte endast hela ord.
+- `false`: Sök inte efter regex‑mönster.
+- `highlightOptions`: Skicka vår markeringskonfiguration.
+
+Denna konfiguration söker efter alla `"lorem"`‑förekomster, ignorerar skiftläge och med markerade utdrag.
+
+### Steg 4: Hantera sökstöd och resultat
+
+**Kontrollera om sökning stöds**
+Vissa format kanske inte stöder sökning — bekräfta alltid:
+
+`parser.isSearchSupported()` returnerar en boolean som indikerar om det laddade dokumentformatet tillåter textsökning.
+
+```java
+if (results == null) {
+ System.out.println("Search isn't supported in this document format.");
+ return;
+}
+```
+
+**Bearbeta varje sökträff**
+Loopa igenom resultaten för att extrahera och visa matchande utdrag med markeringar:
+
+`SearchResult`‑objekt ger åtkomst till den matchade frasen och dess omgivande kontext.
+
+```java
+for (SearchResult result : results) {
+ String snippet = String.format("%s%s%s",
+ result.getLeftHighlightItem().getText(),
+ result.getText(),
+ result.getRightHighlightItem().getText());
+ System.out.println(snippet);
+}
+```
+
+## Vanliga problem och lösningar
+
+| Problem | Orsak | Lösning |
+|---------|-------|---------|
+| **Inga resultat returnerade** | Dokumentformatet stöder inte sökning | Verifiera att `parser.isSearchSupported()` returnerar `true`. |
+| **Markeringsradien verkar för liten** | Standardradien är 10 tecken | Öka radien i `HighlightOptions` (t.ex. `new HighlightOptions(20)`). |
+| **Out‑of‑memory‑fel på stora PDF‑filer** | Hela filen laddas in i minnet | Använd `Parser` i streaming‑läge eller bearbeta filen i delar; GroupDocs.Parser strömmar redan stora filer effektivt. |
+| **Skiftlägeskänslighet fungerar inte som förväntat** | `caseSensitive`‑flaggan felinställd | Säkerställ att `SearchOptions(true, …)` sätter rätt boolean för skiftlägesokänslighet. |
+
+## Vanliga frågor
+
+**Q: Kan jag söka flera nyckelord samtidigt?**
+A: Inte direkt; iterera över varje nyckelord eller konstruera ett regex‑mönster som matchar alla önskade termer.
+
+**Q: Påverkar markeringsradien alla dokumentformat?**
+A: För de flesta stödda format fungerar radien enhetligt; vissa bildbaserade format ignorerar den eftersom de saknar inbyggda textlager.
+
+**Q: Kan jag ändra markeringsfärger?**
+A: `HighlightOptions` styr kontextradien; visuella färger beror på den visare du använder för att rendera PDF‑filen, inte på parsern själv.
+
+**Q: Är sökningen skiftlägeskänslig som standard?**
+A: Nej. Genom att sätta `caseSensitive` till `false` i `SearchOptions` blir sökningen skiftlägesokänslig.
+
+**Q: Fungerar detta med skannade bilder eller bara textbaserade filer?**
+A: Sökning fungerar på textbaserade dokument. För skannade bilder behövs OCR‑funktionalitet, vilket GroupDocs OCR erbjuder som en separat modul.

+
+## Vad är GroupDocs.Parser?
+GroupDocs.Parser är ett Java‑bibliotek som extraherar text, bilder och metadata från över 50 dokumentformat, inklusive EPUB. Det tillhandahåller en hög‑nivå `Parser`‑klass som abstraherar filhantering, så att du kan fokusera på söklogik snarare än låg‑nivå‑parsing. Biblioteket strömmar innehåll effektivt, stödjer minnesbegränsade miljöer och erbjuder inbyggda sökfunktioner som arbetar direkt på den parsade texten.
+
+## Varför använda regex med GroupDocs.Parser för EPUB?
+- **Brett formatstöd:** Hanterar 50+ inmatningsformat, inklusive EPUB, utan externa konverterare.
+- **Minneseffektiv bearbetning:** Strömmar innehåll, vilket möjliggör sökning i EPUB‑filer med flera hundra sidor utan att ladda hela filen i RAM.
+- **Precist mönstermatchning:** Regex låter dig hitta hela ord, fraser eller komplexa mönster (t.ex. datum, ISBN‑nummer) i ett enda anrop.
+
+## Förutsättningar
+- **Java Development Kit (JDK) 8+** installerat och konfigurerat i din IDE eller byggverktyg.
+- **GroupDocs.Parser for Java**‑bibliotek (tillgängligt via Maven eller direkt nedladdning).
+- Grundläggande kunskap om Java‑syntax och reguljära uttryckskoncept.
+
+## Hur man använder regex för att söka text i EPUB‑filer?
+Läs in din EPUB med `new Parser("book.epub")` och anropa `search` med ett kompilerat `Pattern`. Detta tvåstegs‑förfarande separerar filinläsning från mönsterexekvering, vilket säkerställer optimal prestanda även för stora samlingar.
+
+### Steg 1: Initiera Parsern
+`Parser`‑klassen är ingångspunkten för att läsa in och hantera en EPUB‑fil.
+```java
+// ```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/parser/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5
+
+
+```
+```
+
+### Steg 2: Bygg ett regex‑mönster
+Javas `Pattern`‑klass kompilerar det reguljära uttrycket. Till exempel, för att hitta vilket ord som helst som börjar med “list” efter ett blankstegstecken, använd `\\slist\\w*`.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+// Initialize Parser object with an EPUB file path
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.epub")) {
+ // Your code here
+}
+```
+```
+
+### Steg 3: Konfigurera sökalternativ
+`SearchOptions` konfigurerar hur sökningen fungerar, t.ex. skiftlägeskänslighet och fuzzy‑matchning.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+String epubFilePath = "YOUR_DOCUMENT_DIRECTORY/sample.epub";
+
+try (Parser parser = new Parser(epubFilePath)) {
+ // Further processing steps go here
+}
+```
+```
+
+### Steg 4: Utför sökningen
+`SearchResult` representerar en enskild träff, inklusive text, sidnummer och teckenoffset.
+```java
+// ```java
+String regexPattern = \\slist; // Matches any word preceded by whitespace and 'list'
+```
+```
+
+### Steg 5: Bearbeta resultaten
+Iterera över `SearchResult`‑samlingen för att logga träffar, lagra dem i en databas eller trigga efterföljande arbetsflöden såsom indexering eller avisering.
+```java
+// ```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options for search
+SearchOptions options = new SearchOptions(true /* case match */, false /* whole word */, true /* fuzzy */);
+```
+```
+
+## Hur man utför en skiftlägeskänslig sökning i Java?
+Ange `SearchOptions.setIgnoreCase(false)` för att tvinga exakt skiftlägesmatchning. Detta är viktigt när du söker efter identifierare, kodsnuttar eller varumärkesnamn som måste behålla sin ursprungliga versal‑/gemener‑form.
+
+## Vanliga användningsfall
+1. **Digitalt bibliotek‑indexering:** Generera automatiskt sökbara index för tusentals EPUB‑titlar.
+2. **Innehållskurering:** Hitta tematiska avsnitt (t.ex. “Chapter 5”) i flera böcker för forskning.
+3. **Datautvinning:** Extrahera strukturerade entiteter som ISBN‑nummer, datum eller författarnamn med skräddarsydda regex‑mönster.
+4. **E‑learning‑integration:** Förbättra kursplattformar med omedelbar fulltext‑sökning för kursmaterial i PDF‑ och EPUB‑format.
+
+## Prestandatips
+- **Optimera regex‑mönster:** Föredra enkla teckenklasser framför back‑tracking‑tunga konstruktioner för att hålla CPU‑användningen låg.
+- **Dela upp stora EPUB‑filer:** Bearbeta kapitel individuellt om filen överstiger 200 MB för att undvika minnesspikar.
+- **Cacha vanliga frågor:** Spara resultat av populära mönster (t.ex. vanliga nyckelord) i en lättviktig minnes‑karta.
+
+## Vanliga frågor
+**Q: Vad är skillnaden mellan `search` och `extractText`?**
+A: `search` tillämpar ett regex‑mönster och returnerar endast matchande fragment, medan `extractText` returnerar hela dokumentets innehåll utan filtrering.
+
+**Q: Kan jag söka i flera EPUB‑filer i ett anrop?**
+A: Ingen enskild API‑anrop bearbetar en batch, men du kan loopa över en fillista och återanvända samma `Pattern` och `SearchOptions` för varje fil.
+
+**Q: Hur fungerar fuzzy‑sökning?**
+A: Aktivera fuzzy‑läge i `SearchOptions` för att tillåta ett Levenshtein‑avstånd på upp till två redigeringar, vilket fångar stavfel och mindre variationer.
+
+**Q: Finns det en gräns för dokumentstorlek?**
+A: GroupDocs.Parser kan hantera EPUB‑filer upp till 500 MB; större filer bör delas upp eller strömmas manuellt.
+
+**Q: Behöver jag en licens för utveckling?**
+A: En gratis provversion ger full API‑åtkomst med en användningsvattenstämpel; en permanent licens tar bort begränsningar och ger kommersiella rättigheter.

+GroupDocs.Parser stöder **70+** in‑ och utdataformat—inklusive HTML, DOCX, XLSX och PDF—samtidigt som det bearbetar dokument med hundratals sidor utan att ladda hela filen i minnet. Dess inbyggda `SearchOptions`‑klass låter dig aktivera reguljära uttryck, kontrollera skiftlägeskänslighet och begränsa resultat, vilket ger snabba och minnes‑effektiva genomsökningar.
+
+## Förutsättningar
+1. **GroupDocs.Parser for Java** (senaste versionen, t.ex. 25.5 eller nyare).
+2. **Java Development Kit** 8 eller senare installerat och konfigurerat i din IDE.
+3. Grundläggande kunskap om **Java regex‑syntax** (t.ex. `\d+`, `\bSub\w*`).
+
+## Installera GroupDocs.Parser för Java
+För att börja, lägg till Maven‑beroendet i din `pom.xml`:
+
+```xml
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5
+
+```
+
+För direkta nedladdningar, besök [GroupDocs.Parser for Java releases](https://releases.groupdocs.com/parser/java/) för att hämta den senaste versionen.
+
+**Licensanskaffning**
+- **Gratis provversion** – utforska kärnfunktioner utan kostnad.
+- **Tillfällig licens** – begär en utökad testnyckel från [GroupDocs' website](https://purchase.groupdocs.com/temporary-license/).
+- **Köp** – skaffa en fullständig licens för obegränsad produktionsanvändning.
+
+**Initiering**
+När biblioteket har lagts till, initiera din Java‑applikation för att använda GroupDocs.Parser:
+
+```java
+import com.groupdocs.parser.Parser;
+
+public class SetupExample {
+ public static void main(String[] args) {
+ String filePath = "path/to/your/document.html";
+ try (Parser parser = new Parser(filePath)) {
+ // Initialization complete, ready to parse and search!
+ } catch (Exception e) {
+ e.printStackTrace();
+ }
+ }
+}
+```
+
+## Hur man söker i HTML med GroupDocs.Parser för Java?
+Läs in din HTML‑fil med `Parser`‑klassen och utför en regex‑sökning på bara två kodrader. `Parser`‑klassen är ingångspunkten som läser och parsar stödda dokumenttyper, och exponerar metoder för textutdragning och sökning. Genom att konfigurera `SearchOptions` instruerar du parsern att behandla ditt mönster som ett reguljärt uttryck, eventuellt med skiftlägeskänslig eller helordssökning.
+
+### Steg‑för‑Steg‑implementation
+
+### Steg 1: Definiera ditt reguljära uttrycksmönster
+Först, skapa regex‑mönstret som matchar den text du behöver. I detta exempel letar vi efter ord som börjar med **“Sub”** följt av en siffra (t.ex. `Sub1`, `Sub9`).
+
+```java
+String regexPattern = "Sub[0-9]";
+```
+
+### Steg 2: Ställ in sökalternativ
+`SearchOptions` är ett konfigurationsobjekt som specificerar sökbeteende såsom regex‑läge och skiftlägeskänslighet.
+Konfigurera `SearchOptions`‑objektet för att aktivera regex‑läge, sätta skiftlägeskänslighet och bestämma om endast hela ord ska matchas. `SearchOptions` är en konfigurationsbehållare som talar om för parsern hur sökningen ska utföras.
+
+```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options: case-sensitive, whole word, use regex
+SearchOptions options = new SearchOptions(true, false, true);
+```
+
+### Steg 3: Utför sökningen
+Anropa `search`‑metoden på en `Parser`‑instans, och skicka HTML‑filens sökväg, mönstret och alternativen. Metoden returnerar en samling av `SearchResult`‑objekt, var och en innehåller den matchade texten och dess plats i dokumentet.
+
+```java
+import com.groupdocs.parser.data.SearchResult;
+
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.html")) {
+ Iterable results = parser.search(regexPattern, options);
+
+ for (SearchResult result : results) {
+ System.out.println(String.format("At %d: %s", result.getPosition(), result.getText()));
+ }
+} catch (Exception e) {
+ e.printStackTrace();
+}
+```
+
+**Viktiga konfigurationsalternativ**
+- **Skiftlägeskänslighet** – sätt `true` för exakt skiftlägesmatchning.
+- **Helordsökning** – `false` inkluderar partiella matchningar.
+- **Använd reguljära uttryck** – måste vara `true` för att aktivera regex‑behandling.
+
+## Vanliga problem och lösningar
+- **Felaktig filsökväg** – verifiera att HTML‑filen är åtkomlig från applikationens arbetskatalog.
+- **Ogiltig regex‑syntax** – testa ditt mönster med en online‑regex‑tester innan du bäddar in det i koden.
+- **Minnesläckor** – stäng alltid `Parser`‑instansen eller använd try‑with‑resources för att säkerställa att strömmar frigörs.
+
+## Praktiska tillämpningar
+Att använda regex‑drivna sökningar i HTML öppnar dörrar till många verkliga scenarier:
+1. **Dataextraktion** – hämta fakturanummer, ID:n eller tidsstämplar från massiva HTML‑rapporter.
+2. **Innehållsfiltrering** – automatiskt ta bort eller flagga sektioner som innehåller förbjudna nyckelord.
+3. **Logganalys** – skanna HTML‑formaterade loggar för felmönster eller prestandamått.
+4. **ETL‑pipelines** – integrera parsern i data‑ingest‑arbetsflöden som normaliserar webb‑scrapad innehåll.
+
+## Prestandaöverväganden
+Vid hantering av stora HTML‑korpor, ha dessa tips i åtanke:
+- **Optimera regex‑mönster** – undvik överdriven backtracking; använd atomiska grupper eller possessiva kvantifierare när det är möjligt.
+- **Strömlinjeforma minnesanvändning** – omge parsning i ett try‑with‑resources‑block för att låta JVM återta buffertar snabbt.
+- **Parallell bearbetning** – utnyttja Javas `ForkJoinPool` för att söka i flera dokument samtidigt, vilket skalar linjärt på fler‑kärniga servrar.
+
+## Vanliga frågor
+
+**Q: Vad är ett reguljärt uttryck?**
+A: Ett reguljärt uttryck (regex) är ett koncist, mönsterbaserat språk för att matcha teckensekvenser inom strängar, som används i stor utsträckning för validering, sökning och textmanipulation.
+
+**Q: Kan GroupDocs.Parser hantera icke‑HTML‑filer?**
+A: Ja, det stöder över 70 format—inklusive PDF, DOCX, XLSX och PPTX—så samma söklogik fungerar över olika dokumenttyper.
+
+**Q: Hur bör jag hantera parsningsfel?**
+A: Omge parsningskoden med ett try‑catch‑block, fånga `ParserException` för att logga problemet och säkerställa att resurser stängs.
+
+**Q: Mitt regex returnerar inga resultat—vad är fel?**
+A: Dubbelkolla mönstret för escapade tecken, verifiera skiftlägeskänslighetsinställningarna och bekräfta att måltexten faktiskt finns i HTML‑källan.
+
+**Q: Finns det någon storleksgräns för HTML‑filer?**
+A: GroupDocs.Parser kan bearbeta filer upp till 2 GB; för extremt stora HTML‑filer, överväg att dela upp dem eller streama sektioner för att hålla dig inom minnesbegränsningarna.
+
+## Slutsats
+Genom att följa den här guiden vet du nu **how to search html** dokument med en kraftfull regex‑motor inbyggd i GroupDocs.Parser för Java. Du kan snabbt lokalisera mönster, extrahera meningsfull data och integrera lösningen i större Java‑applikationer eller datapipelines.
+
+**Nästa steg:** experimentera med mer komplexa mönster, kombinera flera `SearchOptions`, eller bädda in parsern i en Spring Boot‑mikrotjänst för on‑demand textutdragning.

+- questions:
+ - answer: Not directly; iterate over each keyword or construct a regex pattern that

+ question: Can I search multiple keywords at once?
+ - answer: For most supported formats the radius works uniformly; some image‑based

+ question: Does the highlight radius affect all document formats?
+ - answer: '`HighlightOptions` controls context radius; visual colors depend on the
+ viewer you use to render the PDF, not the parser itself.'
+ question: Can I change highlight colors?
+ - answer: No. By setting `caseSensitive` to `false` in `SearchOptions`, the search
+ becomes case‑insensitive.
+ question: Is search case‑sensitive by default?
+ - answer: Search works on text‑based documents. For scanned images you need OCR
+ capabilities, which GroupDocs OCR provides as a separate module.

+`Java PDF processing` คือชุดของการดำเนินการเชิงโปรแกรม—เช่นการสกัดข้อมูล, การค้นหา, และการไฮไลท์ข้อความ—ที่ทำบนไฟล์ PDF ด้วยไลบรารี Java ด้วย GroupDocs.Parser คุณสามารถค้นหาเอกสารที่รองรับใด ๆ ดึงบริบทรอบ ๆ และใช้ไฮไลท์แบบภาพได้ทั้งหมดโดยไม่ต้องเปิดไฟล์ในโปรแกรมดู นี่ทำให้คุณสร้างคลังข้อมูลที่ค้นหาได้เร็วและไหลงานตรวจทานอัตโนมัติที่ขยายได้ถึงหลายพันหน้าในแต่ละเอกสาร
+
+## ทำไมต้องใช้ GroupDocs.Parser สำหรับ java pdf processing?
+GroupDocs.Parser รองรับ **ไฟล์รูปแบบกว่า 50** และสามารถประมวลผล **PDF หลายร้อยหน้า** ได้โดยไม่ต้องโหลดไฟล์ทั้งหมดเข้าสู่หน่วยความจำ ลดการใช้ RAM ได้ถึง **70 %** เมื่อเทียบกับวิธีแบบง่าย ๆ เครื่องมือค้นหาของมันคืนค่า offset ที่แม่นยำ ทำให้คุณสร้างไฮไลท์ UI แบบกำหนดเองหรือส่งออกผลลัพธ์ไปยังระบบอื่นได้ ไลบรารีนี้ได้รับการบำรุงรักษาอย่างต่อเนื่อง เข้ากันได้กับ Java 8+ และมี artifacts ของ Maven และ Gradle เพื่อการรวมที่ง่าย
+
+## ข้อกำหนดเบื้องต้น
+
+ก่อนที่เราจะเริ่มทำงาน โปรดตรวจสอบว่าคุณมีสิ่งจำเป็นต่อไปนี้พร้อมใช้งาน:
+
+- **สภาพแวดล้อมการพัฒนา Java**: ติดตั้ง JDK 8+ แล้ว.
+- **Maven หรือ Gradle**: สำหรับการจัดการ dependencies และการตั้งค่าโครงการ.
+- **ไลบรารี GroupDocs.Parser for Java**: ดาวน์โหลดหรือเพิ่มผ่าน dependency.
+- **เอกสารตัวอย่าง**: PDF หรือข้อความทดสอบสำหรับการค้นหา.
+- **ความรู้พื้นฐาน Java**: ความคุ้นเคยกับคลาส, เมธอด, และการจัดการไฟล์.
+
+หากคุณยังไม่มีไลบรารี คุณสามารถดาวน์โหลดเวอร์ชันล่าสุดจาก [ดาวน์โหลด GroupDocs](https://releases.groupdocs.com/parser/java/) หรือเพิ่มผ่าน Maven:
+
+```xml
+
+ com.groupdocs
+ groupdocs-parser
+ 21.12
+
+```
+
+## นำเข้าแพ็กเกจ
+
+เพื่อเริ่มต้น ให้เรานำเข้าคลาสที่จำเป็นจาก GroupDocs.Parser: `Parser` คือคลาสหลักที่ใช้โหลดและโต้ตอบกับเอกสาร `HighlightOptions` กำหนดวิธีการไฮไลท์ข้อความที่ตรงกัน `SearchOptions` กำหนดพฤติกรรมการค้นหาเช่นการแยกแยะตัวพิมพ์ `SearchResult` แสดงผลการจับคู่แต่ละรายการในเอกสาร.
+
+```java
+import com.groupdocs.parser.Parser;
+import com.groupdocs.parser.search.HighlightOptions;
+import com.groupdocs.parser.search.SearchOptions;
+import com.groupdocs.parser.search.SearchResult;
+```
+
+การนำเข้าเหล่านี้ครอบคลุมฟังก์ชันหลักสำหรับการแยกเอกสาร, การตั้งค่าไฮไลท์, และการดำเนินการค้นหา.
+
+## การทำงานของกระบวนการค้นหาและไฮไลท์เป็นอย่างไร?
+
+โหลด PDF ของคุณ, ตั้งค่าอ็อบเจ็กต์ `HighlightOptions`, เรียกใช้ `parser.search` แล้ววนลูปผ่านคอลเลกชัน `SearchResult` เพื่อสร้างส่วนที่ไฮไลท์ กระบวนการทั้งหมดทำงานเป็นสองขั้นตอน: ขั้นแรก parser อ่านโครงสร้างเอกสาร; ขั้นที่สองเครื่องมือค้นหาสแกนสตรีมข้อความโดยใช้ตัวเลือกที่คุณกำหนด วิธีนี้ทำให้ประสิทธิภาพสูงแม้กับไฟล์ขนาดใหญ่.
+
+## คู่มือขั้นตอนต่อขั้นในการค้นหาข้อความพร้อมไฮไลท์
+
+เราจะเดินผ่านกระบวนการที่แบ่งเป็นขั้นตอนที่จัดการได้และชัดเจน แต่ละขั้นมีคำอธิบายของตนเองเพื่อช่วยให้คุณเข้าใจเหตุผลและวิธีการ
+
+### ขั้นตอนที่ 1: เริ่มต้น Parser ด้วยเอกสารของคุณ
+
+**เกิดอะไรขึ้นที่นี่?**
+การสร้างอินสแตนซ์ของคลาส `Parser` ที่เชื่อมโยงกับไฟล์เอกสารของคุณทำให้คุณสามารถเข้าถึงและวิเคราะห์เนื้อหาได้
+
+`Parser` โหลดเอกสารและให้เมธอดสำหรับการสกัดข้อความและการค้นหา.
+
+```java
+try (Parser parser = new Parser("path/to/your/document.pdf")) {
+ // your code here
+}
+```
+
+**ในความเป็นจริง:**
+คำสั่ง `try-with-resources` ทำให้แน่ใจว่าไฟล์ของคุณถูกปิดอย่างถูกต้องหลังการประมวลผล ป้องกันการรั่วของทรัพยากร แทนที่ `"path/to/your/document.pdf"` ด้วยเส้นทางไฟล์หรือ URL ที่แม่นยำของคุณ.
+
+### ขั้นตอนที่ 2: ตั้งค่า Highlight Options
+
+**ทำไมต้องกำหนด Highlight Options?**
+คุณอาจต้องการควบคุมลักษณะหรือพฤติกรรมของการไฮไลท์ผลการค้นหา—เช่นจำนวนอักขระที่แสดงรอบการจับคู่หรือสี (หากรองรับ)
+
+ในตัวอย่างนี้ เราตั้งรัศมีไฮไลท์เป็น 15 อักขระ:
+
+`HighlightOptions` ระบุรัศมีบริบทและการตั้งค่าภาพสำหรับผลการค้นหาที่ไฮไลท์.
+
+```java
+HighlightOptions highlightOptions = new HighlightOptions(15);
+```
+
+นี่จะห่อหุ้มข้อความที่พบด้วยบริบทรอบ ๆ—เหมือนแว่นขยายรอบคีย์เวิร์ดของคุณ—ทำให้ง่ายต่อการเห็นตำแหน่งที่ตรงกัน.
+
+### ขั้นตอนที่ 3: ดำเนินการค้นหาในเอกสาร
+
+**การค้นหาทำงานอย่างไร?**
+โดยใช้ `parser.search` คุณระบุคีย์เวิร์ดหรือวลี, ตัวเลือกการค้นหา, แล้วรับคอลเลกชันที่สามารถวนได้ของอ็อบเจ็กต์ `SearchResult`
+
+`SearchOptions` ตั้งค่าพารามิเตอร์การค้นหาเช่นการแยกแยะตัวพิมพ์ `SearchResult` เก็บรายละเอียดของแต่ละการจับคู่ รวมถึงข้อความที่ตรงและตำแหน่งของมัน.
+
+```java
+Iterable results = parser.search("lorem", new SearchOptions(true, false, false, highlightOptions));
+```
+
+อธิบายคอนสตรัคเตอร์ของ `SearchOptions`:
+
+- `true`: เปิดการค้นหาแบบไม่แยกแยะตัวพิมพ์.
+- `false`: ไม่จำกัดให้ตรงกับคำเต็มเท่านั้น.
+- `false`: ไม่ค้นหาแบบ regex.
+- `highlightOptions`: ส่งค่าการตั้งค่าไฮไลท์ของเรา.
+
+การตั้งค่านี้จะค้นหาทุกการปรากฏของ `"lorem"` โดยไม่สนใจตัวพิมพ์ และสร้างส่วนที่ไฮไลท์.
+
+### ขั้นตอนที่ 4: จัดการการสนับสนุนการค้นหาและผลลัพธ์
+
+**ตรวจสอบว่าการค้นหาถูกสนับสนุนหรือไม่**
+บางรูปแบบอาจไม่รองรับการค้นหา — ควรตรวจสอบเสมอ:
+
+`parser.isSearchSupported()` คืนค่า boolean ที่บ่งบอกว่ารูปแบบเอกสารที่โหลดรองรับการค้นหาข้อความหรือไม่.
+
+```java
+if (results == null) {
+ System.out.println("Search isn't supported in this document format.");
+ return;
+}
+```
+
+**ประมวลผลแต่ละผลการค้นหา**
+วนลูปผ่านผลลัพธ์เพื่อสกัดและแสดงส่วนที่ตรงกับไฮไลท์:
+
+อ็อบเจ็กต์ `SearchResult` ให้เข้าถึงวลีที่ตรงและบริบทรอบ ๆ
+
+```java
+for (SearchResult result : results) {
+ String snippet = String.format("%s%s%s",
+ result.getLeftHighlightItem().getText(),
+ result.getText(),
+ result.getRightHighlightItem().getText());
+ System.out.println(snippet);
+}
+```
+
+## ปัญหาทั่วไปและวิธีแก้
+
+| ปัญหา | สาเหตุ | วิธีแก้ |
+|-------|--------|-----|
+| **ไม่มีผลลัพธ์คืนค่า** | รูปแบบเอกสารไม่รองรับการค้นหา | ตรวจสอบว่า `parser.isSearchSupported()` คืนค่า `true`. |
+| **รัศมีไฮไลท์ดูเหมือนเล็กเกินไป** | รัศมีเริ่มต้นคือ 10 อักขระ | เพิ่มรัศมีใน `HighlightOptions` (เช่น `new HighlightOptions(20)`). |
+| **ข้อผิดพลาด Out‑of‑memory บน PDF ขนาดใหญ่** | ไฟล์ทั้งหมดถูกโหลดเข้าสู่หน่วยความจำ | ใช้ `Parser` ในโหมดสตรีมมิ่งหรือประมวลผลไฟล์เป็นชิ้นส่วน; GroupDocs.Parser มีการสตรีมไฟล์ขนาดใหญ่อย่างมีประสิทธิภาพแล้ว. |
+| **การแยกแยะตัวพิมพ์ไม่ทำงานตามที่คาดหวัง** | แฟล็ก `caseSensitive` ตั้งค่าไม่ถูกต้อง | ตรวจสอบว่า `SearchOptions(true, …)` ตั้งค่า boolean ที่ถูกต้องสำหรับการไม่แยกแยะตัวพิมพ์. |
+
+## คำถามที่พบบ่อย
+
+**Q: ฉันสามารถค้นหาคำหลายคำพร้อมกันได้หรือไม่?**
+A: ไม่โดยตรง; ให้วนลูปแต่ละคีย์เวิร์ดหรือสร้างแพทเทิร์น regex ที่จับคำที่ต้องการทั้งหมด.
+
+**Q: รัศมีไฮไลท์มีผลต่อรูปแบบเอกสารทั้งหมดหรือไม่?**
+A: สำหรับรูปแบบที่รองส่วนใหญ่ รัศมีทำงานสม่ำเสมอ; บางรูปแบบที่เป็นภาพจะละเลยเนื่องจากไม่มีเลเยอร์ข้อความพื้นฐาน.
+
+**Q: ฉันสามารถเปลี่ยนสีไฮไลท์ได้หรือไม่?**
+A: `HighlightOptions` ควบคุมรัศมีบริบท; สีภาพขึ้นอยู่กับโปรแกรมดู PDF ที่คุณใช้ ไม่ได้มาจาก parser เอง.
+
+**Q: การค้นหาแยกแยะตัวพิมพ์โดยค่าเริ่มต้นหรือไม่?**
+A: ไม่. โดยการตั้งค่า `caseSensitive` เป็น `false` ใน `SearchOptions` การค้นหาจะไม่แยกแยะตัวพิมพ์.
+
+**Q: วิธีนี้ทำงานกับภาพสแกนหรือเฉพาะไฟล์ที่เป็นข้อความเท่านั้น?**
+A: การค้นหาทำงานกับเอกสารที่เป็นข้อความ. สำหรับภาพสแกนต้องใช้ความสามารถ OCR ซึ่ง GroupDocs OCR มีเป็นโมดูลแยก.

+
+## GroupDocs.Parser คืออะไร?
+GroupDocs.Parser is a Java library that extracts text, images, and metadata from over 50 document formats, including EPUB. It provides a high‑level `Parser` class that abstracts file handling, letting you focus on search logic rather than low‑level parsing. The library streams content efficiently, supports memory‑constrained environments, and offers built‑in search capabilities that work directly on the parsed text.
+
+## ทำไมต้องใช้ Regex กับ GroupDocs.Parser สำหรับ EPUB?
+- **การสนับสนุนรูปแบบที่กว้างขวาง:** Handles 50+ input formats, EPUB included, without external converters.
+- **Memory‑efficient processing:** Streams content, allowing multi‑hundred‑page EPUBs to be searched without loading the entire file into RAM.
+- **Precise pattern matching:** Regex lets you locate whole words, phrases, or complex patterns (e.g., dates, ISBNs) in a single call.
+
+## ข้อกำหนดเบื้องต้น
+- **Java Development Kit (JDK) 8+** installed and configured in your IDE or build tool.
+- **GroupDocs.Parser for Java** library (available via Maven or direct download).
+- ความคุ้นเคยพื้นฐานกับไวยากรณ์ Java และแนวคิดของ regular‑expression
+
+## วิธีใช้ Regex เพื่อค้นหาข้อความในไฟล์ EPUB?
+
+Load your EPUB with `new Parser("book.epub")` and invoke `search` using a compiled `Pattern`. This two‑step approach isolates file loading from pattern execution, ensuring optimal performance even on large collections.
+
+### ขั้นตอน 1: เริ่มต้น Parser
+The `Parser` class is the entry point for loading and handling an EPUB file.
+```java
+// ```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/parser/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5
+
+
+```
+```
+
+### ขั้นตอน 2: สร้าง Regex Pattern
+Java’s `Pattern` class compiles the regular expression. For example, to find any word that starts with “list” after a whitespace character, use `\\slist\\w*`.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+// Initialize Parser object with an EPUB file path
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.epub")) {
+ // Your code here
+}
+```
+```
+
+### ขั้นตอน 3: กำหนดค่า Search Options
+`SearchOptions` configures how the search operates, such as case sensitivity and fuzzy matching.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+String epubFilePath = "YOUR_DOCUMENT_DIRECTORY/sample.epub";
+
+try (Parser parser = new Parser(epubFilePath)) {
+ // Further processing steps go here
+}
+```
+```
+
+### ขั้นตอน 4: ดำเนินการค้นหา
+`SearchResult` represents a single match, including text, page number, and character offsets.
+```java
+// ```java
+String regexPattern = \\slist; // Matches any word preceded by whitespace and 'list'
+```
+```
+
+### ขั้นตอน 5: ประมวลผลผลลัพธ์
+Iterate over the `SearchResult` collection to log matches, store them in a database, or trigger downstream workflows such as indexing or alerting.
+```java
+// ```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options for search
+SearchOptions options = new SearchOptions(true /* case match */, false /* whole word */, true /* fuzzy */);
+```
+```
+
+## วิธีทำการค้นหาแบบแยกแยะตัวพิมพ์ใหญ่‑เล็กใน Java?
+Set `SearchOptions.setIgnoreCase(false)` to enforce exact‑case matching. This is essential when searching identifiers, code snippets, or brand names that must retain their original casing.
+
+## กรณีการใช้งานทั่วไป
+1. **การทำดัชนีห้องสมุดดิจิทัล:** Automatically generate searchable indexes for thousands of EPUB titles.
+2. **Content Curation:** Locate thematic sections (e.g., “Chapter 5”) across multiple books for research.
+3. **Data Mining:** Extract structured entities like ISBNs, dates, or author names using tailored regex patterns.
+4. **E‑Learning Integration:** Enhance course platforms with instant full‑text search capabilities for course material PDFs and EPUBs.
+
+## เคล็ดลับด้านประสิทธิภาพ
+- **Optimize regex patterns:** Prefer simple character classes over back‑tracking‑heavy constructs to keep CPU usage low.
+- **Chunk large EPUBs:** Process chapters individually if the file exceeds 200 MB to avoid memory spikes.
+- **Cache frequent queries:** Store results of popular patterns (e.g., common keywords) in a lightweight in‑memory map.
+
+## คำถามที่พบบ่อย
+
+**Q: ความแตกต่างระหว่าง `search` กับ `extractText` คืออะไร?**
+A: `search` applies a regex pattern and returns only matching fragments, while `extractText` returns the entire document content without filtering.
+
+**Q: ฉันสามารถค้นหาไฟล์ EPUB หลายไฟล์ในคำสั่งเดียวได้หรือไม่?**
+A: No single API call processes a batch, but you can loop over a file list, reusing the same `Pattern` and `SearchOptions` for each file.
+
+**Q: การค้นหาแบบ fuzzy ทำงานอย่างไร?**
+A: Enable fuzzy mode in `SearchOptions` to allow a Levenshtein distance of up to two edits, which captures misspellings and minor variations.
+
+**Q: มีขีดจำกัดขนาดเอกสารหรือไม่?**
+A: GroupDocs.Parser can handle EPUBs up to 500 MB; larger files should be split or streamed manually.
+
+**Q: ฉันต้องการใบอนุญาตสำหรับการพัฒนาหรือไม่?**
+A: A free trial provides full API access with a usage watermark; a permanent license removes restrictions and grants commercial rights.

+
+## “how to search html” กับ regex คืออะไร?
+**“How to search html”** หมายถึงการใช้ regular expressions เพื่อค้นหารูปแบบข้อความภายใน markup ของ HTML. เทคนิคนี้ทำให้คุณสามารถระบุตำแหน่งคำ, ตัวเลข, หรือแท็กที่กำหนดเองได้โดยไม่ต้องพาร์สต้นไม้ DOM ทั้งหมด. ด้วยการใช้ regex โดยตรงกับแหล่งที่มาของ HTML ดิบ นักพัฒนาสามารถดึงข้อมูลเฉพาะอย่างรวดเร็ว, ตรวจสอบความถูกต้องของเนื้อหา, หรือกรองส่วนต่าง ๆ, ทำให้เป็นทางเลือกที่เบากว่าการพาร์ส DOM ทั้งหมด.
+
+## ทำไมต้องใช้ GroupDocs.Parser สำหรับ Java สำหรับการค้นหา regex?
+GroupDocs.Parser รองรับ **70+** รูปแบบการนำเข้าและส่งออก—including HTML, DOCX, XLSX, และ PDF—พร้อมประมวลผลเอกสารหลายร้อยหน้าโดยไม่ต้องโหลดไฟล์ทั้งหมดเข้าสู่หน่วยความจำ. คลาส `SearchOptions` ที่เป็นเนทีฟของมันทำให้คุณสามารถเปิดใช้งาน regular expressions, ควบคุมความไวต่อกรณี (case sensitivity), และจำกัดผลลัพธ์, ให้การสแกนที่เร็วและใช้หน่วยความจำน้อย.
+
+## ข้อกำหนดเบื้องต้น

+- **Purchase** – รับใบอนุญาตเต็มรูปแบบสำหรับการใช้งานผลิตภัณฑ์ไม่จำกัด.
+
+**Initialization**
+เมื่อเพิ่มไลบรารีแล้ว, เริ่มต้นแอปพลิเคชัน Java ของคุณให้ใช้ GroupDocs.Parser:
+
+```java
+import com.groupdocs.parser.Parser;
+
+public class SetupExample {
+ public static void main(String[] args) {
+ String filePath = "path/to/your/document.html";
+ try (Parser parser = new Parser(filePath)) {
+ // Initialization complete, ready to parse and search!
+ } catch (Exception e) {
+ e.printStackTrace();
+ }
+ }
+}
+```
+
+## วิธีค้นหา HTML ด้วย GroupDocs.Parser สำหรับ Java?
+โหลดไฟล์ HTML ของคุณด้วยคลาส `Parser` และดำเนินการค้นหา regex เพียงสองบรรทัดของโค้ด. คลาส `Parser` เป็นจุดเริ่มต้นที่อ่านและพาร์สประเภทเอกสารที่รองรับ, เปิดเผยเมธอดสำหรับการสกัดข้อความและการค้นหา. โดยการกำหนดค่า `SearchOptions`, คุณบอก parser ให้ถือรูปแบบของคุณเป็น regular expression, พร้อมเปิดใช้งานการจับคู่ที่คำนึงถึงตัวพิมพ์หรือการจับคู่แบบคำเต็มตามต้องการ.
+
+### การดำเนินการตามขั้นตอน
+
+### ขั้นตอนที่ 1: กำหนดรูปแบบ Regular Expression ของคุณ
+ก่อนอื่น, สร้างรูปแบบ regex ที่ตรงกับข้อความที่คุณต้องการ. ในตัวอย่างนี้เรามองหาคำที่เริ่มด้วย **“Sub”** ตามด้วยตัวเลข (เช่น `Sub1`, `Sub9`).
+
+```java
+String regexPattern = "Sub[0-9]";
+```
+
+### ขั้นตอนที่ 2: ตั้งค่า Search Options
+`SearchOptions` เป็นอ็อบเจ็กต์กำหนดค่าที่ระบุพฤติกรรมการค้นหาเช่นโหมด regex และความไวต่อกรณี.
+กำหนดอ็อบเจ็กต์ `SearchOptions` เพื่อเปิดใช้งานโหมด regex, ตั้งค่าความไวต่อกรณี, และตัดสินใจว่าจะจับคู่เฉพาะคำเต็มหรือไม่. `SearchOptions` เป็นตัวเก็บการกำหนดค่าที่บอก parser ว่าจะทำการค้นหาอย่างไร.
+
+```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options: case-sensitive, whole word, use regex
+SearchOptions options = new SearchOptions(true, false, true);
+```
+
+### ขั้นตอนที่ 3: ดำเนินการค้นหา
+เรียกเมธอด `search` บนอินสแตนซ์ `Parser`, ส่งพาธไฟล์ HTML, รูปแบบ, และตัวเลือก. เมธอดจะคืนคอลเลกชันของอ็อบเจ็กต์ `SearchResult`, แต่ละอ็อบเจ็กต์มีข้อความที่ตรงกันและตำแหน่งในเอกสาร.
+
+```java
+import com.groupdocs.parser.data.SearchResult;
+
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.html")) {
+ Iterable results = parser.search(regexPattern, options);
+
+ for (SearchResult result : results) {
+ System.out.println(String.format("At %d: %s", result.getPosition(), result.getText()));
+ }
+} catch (Exception e) {
+ e.printStackTrace();
+}
+```
+
+**Key Configuration Options**
+- **Case Sensitivity** – ตั้งค่า `true` สำหรับการจับคู่ที่ตรงกับตัวพิมพ์.
+- **Whole Word Search** – `false` รวมการจับคู่บางส่วน.
+- **Use Regular Expressions** – ต้องเป็น `true` เพื่อเปิดใช้งานการประมวลผล regex.
+
+## ปัญหาทั่วไปและวิธีแก้
+- **Incorrect file path** – ตรวจสอบว่าไฟล์ HTML สามารถเข้าถึงได้จากไดเรกทอรีทำงานของแอปพลิเคชันของคุณ.
+- **Invalid regex syntax** – ทดสอบรูปแบบของคุณด้วยเครื่องมือทดสอบ regex ออนไลน์ก่อนนำไปใส่ในโค้ด.
+- **Memory leaks** – ปิดอินสแตนซ์ `Parser` เสมอหรือใช้ try‑with‑resources เพื่อให้แน่ใจว่าการสตรีมถูกปล่อย.
+
+## การประยุกต์ใช้ในทางปฏิบัติ
+การใช้การค้นหาแบบ regex ใน HTML เปิดโอกาสสู่หลายสถานการณ์จริง:
+
+1. **Data Extraction** – ดึงหมายเลขใบแจ้งหนี้, ID, หรือ timestamp จากรายงาน HTML จำนวนมาก.
+2. **Content Filtering** – ลบหรือทำเครื่องหมายส่วนที่มีคำสำคัญที่ห้ามโดยอัตโนมัติ.
+3. **Log Analysis** – สแกนบันทึกที่จัดรูปแบบเป็น HTML เพื่อหารูปแบบข้อผิดพลาดหรือเมตริกประสิทธิภาพ.
+4. **ETL Pipelines** – ผสานรวม parser เข้าในกระบวนการ ingest ข้อมูลที่ทำให้เนื้อหาที่ดึงจากเว็บเป็นมาตรฐาน.
+
+## พิจารณาด้านประสิทธิภาพ
+เมื่อจัดการกับคอร์ปัส HTML ขนาดใหญ่, ควรจำแนวทางต่อไปนี้:
+
+- **Optimize regex patterns** – หลีกเลี่ยง backtracking มากเกินไป; ใช้ atomic groups หรือ possessive quantifiers เมื่อเป็นไปได้.
+- **Streamline memory usage** – ห่อการพาร์สในบล็อก try‑with‑resources เพื่อให้ JVM คืนบัฟเฟอร์อย่างรวดเร็ว.
+- **Parallel processing** – ใช้ `ForkJoinPool` ของ Java เพื่อค้นหาเอกสารหลายไฟล์พร้อมกัน, ขยายได้เชิงเส้นบนเซิร์ฟเวอร์หลายคอร์.
+
+## คำถามที่พบบ่อย
+
+**Q: regular expression คืออะไร?**
+A: regular expression (regex) เป็นภาษาที่กระชับและอิงรูปแบบสำหรับการจับคู่ลำดับอักขระภายในสตริง, ใช้กันอย่างกว้างขวางสำหรับการตรวจสอบ, การค้นหา, และการจัดการข้อความ.
+
+**Q: GroupDocs.Parser สามารถจัดการไฟล์ที่ไม่ใช่ HTML ได้หรือไม่?**
+A: ใช่, รองรับมากกว่า 70 รูปแบบ—including PDF, DOCX, XLSX, และ PPTX—ดังนั้นตรรกะการค้นหาเดียวกันทำงานได้กับประเภทเอกสารที่หลากหลาย.
+
+**Q: ควรจัดการข้อผิดพลาดการพาร์สอย่างไร?**
+A: ห่อโค้ดการพาร์สในบล็อก try‑catch, จับ `ParserException` เพื่อบันทึกปัญหาและให้แน่ใจว่าทรัพยากรถูกปิด.
+
+**Q: regex ของฉันไม่ให้ผลลัพธ์—มีอะไรผิด?**
+A: ตรวจสอบรูปแบบสำหรับอักขระที่ต้องหลีกเลี่ยง, ยืนยันการตั้งค่าความไวต่อกรณี, และตรวจสอบว่าข้อความเป้าหมายมีอยู่จริงในแหล่งที่มาของ HTML.
+
+**Q: มีขีดจำกัดขนาดไฟล์ HTML หรือไม่?**
+A: GroupDocs.Parser สามารถประมวลผลไฟล์ได้สูงสุด 2 GB; สำหรับไฟล์ HTML ที่ใหญ่มาก, พิจารณาแยกไฟล์หรือสตรีมส่วนเพื่ออยู่ในขอบเขตหน่วยความจำ.
+
+## สรุป
+โดยทำตามคู่มือนี้คุณจะรู้ **วิธีค้นหา html** ด้วยเอนจิน regex ที่ทรงพลังซึ่งฝังอยู่ใน GroupDocs.Parser for Java. คุณสามารถค้นหารูปแบบได้อย่างรวดเร็ว, ดึงข้อมูลที่มีความหมาย, และผสานโซลูชันนี้เข้าในแอปพลิเคชัน Java ขนาดใหญ่หรือไพป์ไลน์ข้อมูล.
+
+**ขั้นตอนต่อไป:** ทดลองกับรูปแบบที่ซับซ้อนมากขึ้น, ผสาน `SearchOptions` หลายตัว, หรือฝัง parser ใน microservice Spring Boot เพื่อสกัดข้อความตามความต้องการ.

+# Java PDF İşleme: Arama ve Vurgulama ile GroupDocs
+
+Kendinizi belgeler denizinde—PDF'ler, Word dosyaları veya diğer formatlar—boğulmuş buluyor musunuz ve belirli kelimeleri ya da ifadeleri zahmetsizce bulabilmeyi ister misiniz? **Java PDF processing** bunu mümkün kılar. Bu rehberde PDF'ler içinde metin aramayı ve **GroupDocs.Parser for Java** kullanarak vurgulanan alıntılar oluşturmayı öğreneceksiniz. Belge‑analiz aracı oluşturuyor ya da içerik incelemesini otomatikleştiriyor olun, aşağıdaki adımlar net, üretim‑hazır bir çözüm sunar.
+
+## Hızlı Yanıtlar
+- **Java'da PDF metin aramasını hangi kütüphane yönetir?** GroupDocs.Parser for Java.
+- **Geliştirme için bir lisansa ihtiyacım var mı?** Geçici bir lisans test için çalışır; üretim için tam lisans gereklidir.
+- **Birden fazla oluşumu aynı anda vurgulayabilir miyim?** Evet—bir vurgulama yarıçapı ayarlayın ve sonuçlar üzerinde yineleyin.
+- **Arama büyük/küçük harfe duyarlı mı?** Varsayılan olarak büyük/küçük harfe duyarsızdır; `SearchOptions` aracılığıyla değiştirebilirsiniz.
+- **Hangi formatlar destekleniyor?** PDF, DOCX, XLSX, PPTX, HTML ve görseller dahil olmak üzere 50'den fazla giriş ve çıkış formatı.
+
+## Java PDF işleme nedir?
+`Java PDF processing`, Java kütüphaneleri kullanarak PDF dosyalarında gerçekleştirilen metin çıkarma, arama ve vurgulama gibi programatik işlemlerin bütünüdür. GroupDocs.Parser ile desteklenen herhangi bir belgeyi arayabilir, çevresel bağlamı alabilir ve görsel vurgulamalar uygulayabilirsiniz; tüm bunlar dosyayı bir görüntüleyicide açmadan yapılır. Bu yetenek, belgeler başına binlerce sayfaya ölçeklenebilen hızlı, aranabilir arşivler ve otomatik inceleme boru hatları oluşturmanıza olanak tanır.
+
+## Neden GroupDocs.Parser'ı Java PDF işleme için kullanmalısınız?
+GroupDocs.Parser **50+ dosya formatını** destekler ve **çok sayfalı PDF'leri** tüm dosyayı belleğe yüklemeden işleyebilir, naif yaklaşımlara göre RAM kullanımını **%70'e** kadar azaltır. Arama motoru kesin konumları döndürür, böylece özel UI vurgulamaları oluşturabilir veya sonuçları diğer sistemlere aktarabilirsiniz. Kütüphane aktif olarak bakımda, Java 8+ ile uyumlu ve kolay entegrasyon için hem Maven hem de Gradle artefaktları sunar.
+
+## Önkoşullar
+
+Kolları sıvamadan önce, aşağıdaki temel gereksinimlerin hazır olduğundan emin olun:
+
+- **Java Development Environment**: JDK 8+ yüklü.
+- **Maven or Gradle**: Bağımlılık yönetimi ve proje kurulumu için.
+- **GroupDocs.Parser for Java library**: İndirin veya bağımlılık olarak ekleyin.
+- **A sample document**: İçinde arama yapacağınız test PDF'leri veya metinler.
+- **Basic Java knowledge**: Sınıflar, metodlar ve dosya işlemleri konusunda temel bilgi.
+
+Henüz kütüphaneyi edinmediyseniz, en son sürümü [GroupDocs Downloads](https://releases.groupdocs.com/parser/java/) adresinden alabilir veya Maven aracılığıyla ekleyebilirsiniz:
+
+```xml
+
+ com.groupdocs
+ groupdocs-parser
+ 21.12
+
+```
+
+## Paketleri İçe Aktarma
+
+Başlamak için GroupDocs.Parser'dan gerekli sınıfları içe aktaralım:
+
+`Parser` belgeleri yüklemek ve onlarla etkileşimde bulunmak için kullanılan temel sınıftır. `HighlightOptions` eşleşen metnin nasıl vurgulanacağını yapılandırır. `SearchOptions` büyük/küçük harf duyarlılığı gibi arama davranışını tanımlar. `SearchResult` belgede bulunan tek bir eşleşmeyi temsil eder.
+
+```java
+import com.groupdocs.parser.Parser;
+import com.groupdocs.parser.search.HighlightOptions;
+import com.groupdocs.parser.search.SearchOptions;
+import com.groupdocs.parser.search.SearchResult;
+```
+
+Bu içe aktarmalar, belgeleri ayrıştırma, vurgulama seçeneklerini ayarlama ve arama işlemlerini gerçekleştirme için temel işlevselliği kapsar.
+
+## Arama ve vurgulama iş akışı nasıl çalışır?
+PDF'nizi yükleyin, bir `HighlightOptions` nesnesi yapılandırın, `parser.search` metodunu çalıştırın ve ardından `SearchResult` koleksiyonunda yineleyerek vurgulanan alıntılar oluşturun. Tüm süreç iki adımlı bir şekilde yürütülür: önce parser belge yapısını okur; ikinci adımda arama motoru, tanımladığınız seçenekleri uygulayarak metin akışını tarar. Bu yaklaşım, büyük dosyalarda bile yüksek performans sağlar.
+
+## Vurgulamalı Metin Arama için Adım Adım Kılavuz
+
+Süreci yönetilebilir, net adımlara bölerek ilerleyelim. Her adım, neden ve nasıl yapıldığını açıklayan bir bölüme sahiptir.
+
+### Adım 1: Parser'ı Belgenizle Başlatın
+
+**What’s happening here?**
+`Parser` sınıfının belgenize bağlı bir örneğini oluşturmak, içeriğine erişmenizi ve analiz etmenizi sağlar.
+
+`Parser` bir belgeyi yükler ve metin çıkarma ve arama için metodlar sunar.
+
+```java
+try (Parser parser = new Parser("path/to/your/document.pdf")) {
+ // your code here
+}
+```
+
+**In actuality:**
+`try-with-resources` ifadesi, dosyanızın işleme sonrası düzgün bir şekilde kapatılmasını sağlar ve kaynak sızıntılarını önler. `"path/to/your/document.pdf"` ifadesini kesin dosya yolunuz veya URL'niz ile değiştirin.
+
+### Adım 2: Vurgulama Seçeneklerini Ayarlayın
+
+**Why define highlight options?**
+Arama sonuçlarının nasıl vurgulanacağını—eşleşme etrafında gösterilecek karakter sayısı veya renk (destekleniyorsa)—kontrol etmek isteyebilirsiniz.
+
+Bu örnekte 15 karakterlik bir vurgulama yarıçapı ayarlıyoruz:
+
+`HighlightOptions` vurgulanan arama sonuçları için bağlam yarıçapını ve görsel ayarları belirler.
+
+```java
+HighlightOptions highlightOptions = new HighlightOptions(15);
+```
+
+Bu, bulunan metni çevresel bağlamla sarar—anahtar kelimelerinizin etrafında bir büyüteç gibi—eşleşmelerin nerede gerçekleştiğini görmeyi kolaylaştırır.
+
+### Adım 3: Belgede Aramayı Gerçekleştirin
+
+**How does the search work?**
+`parser.search` kullanarak anahtar kelimeyi veya ifadeyi, arama seçeneklerini belirtebilir ve ardından `SearchResult` nesnelerinin yinelemeli bir koleksiyonunu alabilirsiniz.
+
+`SearchOptions` büyük/küçük harf duyarlılığı gibi arama parametrelerini yapılandırır. `SearchResult` her eşleşmenin detaylarını, eşleşen metni ve konumunu içerir.
+
+```java
+Iterable results = parser.search("lorem", new SearchOptions(true, false, false, highlightOptions));
+```
+
+`SearchOptions` yapıcı açıklaması:
+
+- `true`: Büyük/küçük harfe duyarsız aramayı etkinleştir.
+- `false`: Yalnızca tam kelime eşleşmesini devre dışı bırak.
+- `false`: Regex desenlerini aramayı devre dışı bırak.
+- `highlightOptions`: Vurgulama yapılandırmamızı geçir.
+
+Bu ayar, `"lorem"` ifadesinin tüm oluşumlarını büyük/küçük harf duyarsız olarak arar ve vurgulanan alıntılar üretir.
+
+### Adım 4: Arama Desteğini ve Sonuçları İşleyin
+
+**Check if search is supported**
+Bazı formatlar aramayı desteklemeyebilir — her zaman kontrol edin:
+
+`parser.isSearchSupported()` yüklü belge formatının metin aramasına izin verip vermediğini belirten bir boolean döndürür.
+
+```java
+if (results == null) {
+ System.out.println("Search isn't supported in this document format.");
+ return;
+}
+```
+
+**Process each search hit**
+Sonuçlar arasında döngü kurarak eşleşen alıntıları vurgularla birlikte çıkarın ve gösterin:
+
+`SearchResult` nesneleri, eşleşen ifadeye ve çevresel bağlama erişim sağlar.
+
+```java
+for (SearchResult result : results) {
+ String snippet = String.format("%s%s%s",
+ result.getLeftHighlightItem().getText(),
+ result.getText(),
+ result.getRightHighlightItem().getText());
+ System.out.println(snippet);
+}
+```
+
+## Yaygın Sorunlar ve Çözümler
+
+| Issue | Reason | Fix |
+|-------|--------|-----|
+| **Sonuç döndürülmedi** | Belge formatı aranabilir değil | `parser.isSearchSupported()`'ın `true` döndürdüğünü doğrulayın. |
+| **Vurgulama yarıçapı çok küçük görünüyor** | Varsayılan yarıçap 10 karakter | `HighlightOptions` içinde yarıçapı artırın (ör. `new HighlightOptions(20)`). |
+| **Büyük PDF'lerde bellek dışı hata** | Tüm dosya belleğe yüklendi | `Parser`'ı akış modunda kullanın veya dosyayı parçalara bölerek işleyin; GroupDocs.Parser zaten büyük dosyaları verimli bir şekilde akışlar. |
+| **Büyük/küçük harf duyarlılığı beklendiği gibi çalışmıyor** | `caseSensitive` bayrağı yanlış ayarlanmış | `SearchOptions(true, …)`'ın büyük/küçük harf duyarsızlığı için doğru boolean değeri ayarladığından emin olun. |
+
+## Sıkça Sorulan Sorular
+
+**Q: Birden fazla anahtar kelimeyi aynı anda arayabilir miyim?**
+A: Doğrudan değil; her anahtar kelimeyi ayrı ayrı yineleyin veya tüm istenen terimleri eşleyecek bir regex deseni oluşturun.
+
+**Q: Vurgulama yarıçapı tüm belge formatlarını etkiler mi?**
+A: Çoğu desteklenen formatta yarıçap aynı şekilde çalışır; bazı görüntü‑tabanlı formatlar yerel metin katmanı olmadığından bunu görmezden gelir.
+
+**Q: Vurgulama renklerini değiştirebilir miyim?**
+A: `HighlightOptions` bağlam yarıçapını kontrol eder; görsel renkler PDF'yi render eden görüntüleyiciye bağlıdır, parser'a değil.
+
+**Q: Arama varsayılan olarak büyük/küçük harfe duyarlı mı?**
+A: Hayır. `SearchOptions` içinde `caseSensitive` değerini `false` olarak ayarlayarak aramayı büyük/küçük harfe duyarsız hâle getirebilirsiniz.
+
+**Q: Bu, taranmış görüntülerde mi yoksa yalnızca metin tabanlı dosyalarda mı çalışır?**
+A: Arama metin tabanlı belgelerde çalışır. Taranmış görüntüler için OCR yeteneklerine ihtiyaç vardır; bu, GroupDocs OCR ayrı bir modül olarak sunar.

+# Regex'i EPUB Metin Araması için GroupDocs.Parser Nasıl Kullanılır
+
+Bu uygulamalı rehberde, Java için GroupDocs.Parser kullanarak EPUB dosyaları içinde metin aramak için **regex'in nasıl kullanılacağını** keşfedeceksiniz. Dijital kütüphane indeksleyicisi oluşturuyor olun ya da binlerce e‑kitapta belirli ifadeleri bulmanız gerekiyor olsun, düzenli ifade aramalarını ustalaşmak zaman kazandırır ve doğruluğu artırır. Kurulum, ana sınıflar ve pratik desenler üzerinden adım adım ilerleyecek, aynı zamanda **epub dosyalarını nasıl etkili bir şekilde arayacağınızı** ele alacağız.
+
+## Hızlı Yanıtlar
+- **Java'da EPUB'i ayrıştıran kütüphane hangisidir?** GroupDocs.Parser for Java.
+- **EPUB araması için regex kullanabilir miyim?** Evet – API Java Pattern nesnelerini kabul eder.
+- **Büyük/küçük harfe duyarlı bir arama nasıl yapılır?** `SearchOptions.setIgnoreCase(false)` ayarlayın.
+- **Lisans gerekiyor mu?** Ücretsiz deneme test için çalışır; tam lisans sınırlamaları kaldırır.
+- **Hangi Java sürümü gereklidir?** JDK 8 veya üzeri.
+
+## GroupDocs.Parser Nedir?
+GroupDocs.Parser, EPUB dahil olmak üzere 50'den fazla belge formatından metin, resim ve meta verileri çıkaran bir Java kütüphanesidir. Dosya işlemlerini soyutlayan yüksek seviyeli `Parser` sınıfını sağlar, böylece düşük seviyeli ayrıştırma yerine arama mantığına odaklanabilirsiniz. Kütüphane içeriği verimli bir şekilde akıtarak, bellek kısıtlı ortamları destekler ve ayrıştırılmış metin üzerinde doğrudan çalışan yerleşik arama yetenekleri sunar.
+
+## EPUB için GroupDocs.Parser ile Neden Regex Kullanmalı?
+- **Geniş format desteği:** 50+ giriş formatını, EPUB dahil, harici dönüştürücüler olmadan işler.
+- **Bellek‑verimli işleme:** İçeriği akıtarak, çok sayfalı EPUB'ların tamamını RAM'e yüklemeden aranmasını sağlar.
+- **Kesin desen eşleştirme:** Regex, tek bir çağrıda tam kelimeleri, ifadeleri veya karmaşık desenleri (ör. tarih, ISBN) bulmanızı sağlar.
+
+## Önkoşullar
+- **Java Development Kit (JDK) 8+** IDE'nizde veya derleme aracınızda kurulu ve yapılandırılmış.
+- **GroupDocs.Parser for Java** kütüphanesi (Maven üzerinden veya doğrudan indirme ile temin edilebilir).
+- Java sözdizimi ve düzenli ifade kavramlarına temel aşinalık.
+
+## EPUB Dosyalarında Metin Aramak İçin Regex Nasıl Kullanılır?
+`new Parser("book.epub")` ile EPUB dosyanızı yükleyin ve derlenmiş bir `Pattern` kullanarak `search` metodunu çağırın. Bu iki adımlı yaklaşım, dosya yüklemeyi desen çalıştırmadan ayırarak, büyük koleksiyonlarda bile optimal performans sağlar.
+
+### Adım 1: Parser'ı Başlatın
+`Parser` sınıfı, bir EPUB dosyasını yüklemek ve işlemek için giriş noktasıdır.
+```java
+// ```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/parser/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5
+
+
+```
+```
+
+### Adım 2: Regex Deseni Oluşturun
+Java'nın `Pattern` sınıfı düzenli ifadeyi derler. Örneğin, bir boşluk karakterinden sonra “list” ile başlayan herhangi bir kelimeyi bulmak için `\\slist\\w*` kullanın.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+// Initialize Parser object with an EPUB file path
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.epub")) {
+ // Your code here
+}
+```
+```
+
+### Adım 3: Arama Seçeneklerini Yapılandırın
+`SearchOptions`, aramanın nasıl çalışacağını, örneğin büyük/küçük harf duyarlılığı ve bulanık eşleştirme gibi ayarları yapılandırır.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+String epubFilePath = "YOUR_DOCUMENT_DIRECTORY/sample.epub";
+
+try (Parser parser = new Parser(epubFilePath)) {
+ // Further processing steps go here
+}
+```
+```
+
+### Adım 4: Aramayı Gerçekleştirin
+`SearchResult`, metin, sayfa numarası ve karakter ofsetleri dahil tek bir eşleşmeyi temsil eder.
+```java
+// ```java
+String regexPattern = \\slist; // Matches any word preceded by whitespace and 'list'
+```
+```
+
+### Adım 5: Sonuçları İşleyin
+`SearchResult` koleksiyonunu döngüyle gezerek eşleşmeleri kaydedebilir, bir veritabanına depolayabilir veya indeksleme ya da uyarı gibi sonraki iş akışlarını tetikleyebilirsiniz.
+```java
+// ```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options for search
+SearchOptions options = new SearchOptions(true /* case match */, false /* whole word */, true /* fuzzy */);
+```
+```
+
+## Java'da Büyük/Küçük Harfe Duyarlı Arama Nasıl Yapılır?
+Tam harf eşleşmesini zorlamak için `SearchOptions.setIgnoreCase(false)` ayarlayın. Bu, tanımlayıcılar, kod parçacıkları veya orijinal büyük/küçük harf durumunu koruması gereken marka adları ararken önemlidir.
+
+## Yaygın Kullanım Senaryoları
+1. **Dijital Kütüphane İndeksleme:** Binlerce EPUB başlığı için otomatik olarak aranabilir indeksler oluşturur.
+2. **İçerik Düzenleme:** Araştırma amacıyla birden fazla kitapta tematik bölümleri (ör. “Chapter 5”) bulur.
+3. **Veri Madenciliği:** Özelleştirilmiş regex desenleri kullanarak ISBN'ler, tarihler veya yazar adları gibi yapılandırılmış varlıkları çıkarır.
+4. **E‑Öğrenme Entegrasyonu:** Kurs materyali PDF'leri ve EPUB'ları için anlık tam metin arama yetenekleriyle kurs platformlarını geliştirir.
+
+## Performans İpuçları
+- **Regex desenlerini optimize edin:** CPU kullanımını düşük tutmak için geri izlemeye (back‑tracking) dayalı karmaşık yapılar yerine basit karakter sınıflarını tercih edin.
+- **Büyük EPUB'ları bölün:** Dosya 200 MB'yi aşarsa, bellek dalgalanmalarını önlemek için bölümleri ayrı ayrı işleyin.
+- **Sık sorguları önbelleğe alın:** Popüler desenlerin (ör. yaygın anahtar kelimeler) sonuçlarını hafif bir bellek içi haritada saklayın.
+
+## Sıkça Sorulan Sorular
+
+**Q: `search` ve `extractText` arasındaki fark nedir?**
+**A:** `search` bir regex deseni uygular ve yalnızca eşleşen parçaları döndürür, `extractText` ise filtreleme yapmadan tüm belge içeriğini döndürür.
+
+**Q: Birden fazla EPUB dosyasını tek bir çağrıda arayabilir miyim?**
+**A:** Tek bir API çağrısı toplu işlem yapmaz, ancak bir dosya listesi üzerinde döngü kurarak aynı `Pattern` ve `SearchOptions` her dosya için yeniden kullanılabilir.
+
+**Q: Bulanık arama nasıl çalışır?**
+**A:** `SearchOptions` içinde bulanık modu etkinleştirerek iki düzenleme kadar Levenshtein mesafesine izin verilir; bu sayede yazım hataları ve küçük varyasyonlar yakalanır.
+
+**Q: Belge boyutu için bir limit var mı?**
+**A:** GroupDocs.Parser 500 MB'a kadar EPUB'ları işleyebilir; daha büyük dosyalar manuel olarak bölünmeli veya akıtılmalıdır.
+
+**Q: Geliştirme için lisansa ihtiyacım var mı?**
+**A:** Ücretsiz deneme, kullanım filigranı ile tam API erişimi sağlar; kalıcı lisans sınırlamaları kaldırır ve ticari haklar verir.

Yerel `SearchOptions` sınıfı, düzenli ifadeleri etkinleştirmenize, büyük/küçük harf duyarlılığını kontrol etmenize ve sonuçları sınırlamanıza olanak tanır; bu da hızlı ve bellek‑verimli taramalar sağlar.
+
+## Önkoşullar
+Başlamadan önce, şunların olduğundan emin olun:
+
+1. **GroupDocs.Parser for Java** (en son sürüm, ör. 25.5 veya daha yeni).
+2. **Java Development Kit** 8 veya daha yeni bir sürüm, IDE'nizde kurulu ve yapılandırılmış.
+3. **Java regex sözdizimi** hakkında temel bir aşinalık (ör. `\d+`, `\bSub\w*`).
+
+## GroupDocs.Parser for Java Kurulumu
+Başlamak için, Maven bağımlılığını `pom.xml` dosyanıza ekleyin:
+
+```xml
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5
+
+```
+

+
+**Başlatma**
+Kütüphane eklendikten sonra, Java uygulamanızı GroupDocs.Parser kullanacak şekilde başlatın:
+
+```java
+import com.groupdocs.parser.Parser;
+
+public class SetupExample {
+ public static void main(String[] args) {
+ String filePath = "path/to/your/document.html";
+ try (Parser parser = new Parser(filePath)) {
+ // Initialization complete, ready to parse and search!
+ } catch (Exception e) {
+ e.printStackTrace();
+ }
+ }
+}
+```
+
+## HTML'i GroupDocs.Parser for Java ile Nasıl Ararsınız?
+`Parser` sınıfı ile HTML dosyanızı yükleyin ve sadece iki satır kodla bir regex araması gerçekleştirin. `Parser` sınıfı, desteklenen belge türlerini okuyan ve ayrıştıran giriş noktasıdır; metin çıkarma ve arama için yöntemler sunar. `SearchOptions` yapılandırmasıyla, deseni bir düzenli ifade olarak ele almasını ve isteğe bağlı olarak büyük/küçük harf duyarlı veya tam kelime eşleşmesini etkinleştirirsiniz.
+
+### Adım‑Adım Uygulama
+
+### Adım 1: Düzenli İfade Deseninizi Tanımlayın
+İlk olarak, ihtiyacınız olan metni eşleyecek regex desenini oluşturun. Bu örnekte, **“Sub”** ile başlayıp bir rakam izleyen kelimeleri arıyoruz (ör. `Sub1`, `Sub9`).
+
+```java
+String regexPattern = "Sub[0-9]";
+```
+
+### Adım 2: Arama Seçeneklerini Ayarlayın
+`SearchOptions`, regex modu ve büyük/küçük harf duyarlılığı gibi arama davranışını belirten bir yapılandırma nesnesidir.
+`SearchOptions` nesnesini regex modunu etkinleştirecek, büyük/küçük harf duyarlılığını ayarlayacak ve yalnızca tam kelimeleri eşleştirip eşleştirmeyeceğinizi belirleyecek şekilde yapılandırın. `SearchOptions`, parser'a aramayı nasıl yapacağını söyleyen bir yapılandırma tutucusudur.
+
+```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options: case-sensitive, whole word, use regex
+SearchOptions options = new SearchOptions(true, false, true);
+```
+
+### Adım 3: Aramayı Gerçekleştirin
+`Parser` örneği üzerinde `search` metodunu çağırın; HTML dosya yolunu, deseni ve seçenekleri geçirin. Metod, eşleşen metni ve belgedeki konumunu içeren `SearchResult` nesnelerinin bir koleksiyonunu döndürür.
+
+```java
+import com.groupdocs.parser.data.SearchResult;
+
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.html")) {
+ Iterable results = parser.search(regexPattern, options);
+
+ for (SearchResult result : results) {
+ System.out.println(String.format("At %d: %s", result.getPosition(), result.getText()));
+ }
+} catch (Exception e) {
+ e.printStackTrace();
+}
+```
+
+**Ana Yapılandırma Seçenekleri**
+- **Case Sensitivity** – tam büyük/küçük harf eşleşmeleri için `true` ayarlayın.
+- **Whole Word Search** – `false` kısmi eşleşmeleri içerir.
+- **Use Regular Expressions** – regex işleme için `true` olmalıdır.
+
+## Yaygın Sorunlar ve Çözümler
+- **Incorrect file path** – HTML dosyasının uygulamanızın çalışma dizininden erişilebilir olduğunu doğrulayın.
+- **Invalid regex syntax** – kod içine yerleştirmeden önce deseni çevrimiçi bir regex test aracında deneyin.
+- **Memory leaks** – her zaman `Parser` örneğini kapatın veya akışların serbest bırakılmasını sağlamak için try‑with‑resources kullanın.
+
+## Pratik Uygulamalar
+HTML'de regex‑tabanlı aramalar kullanmak, birçok gerçek dünya senaryosunun kapılarını açar:
+1. **Data Extraction** – toplu HTML raporlarından fatura numaralarını, kimlikleri veya zaman damgalarını çekin.
+2. **Content Filtering** – yasaklı anahtar kelimeler içeren bölümleri otomatik olarak kaldırın veya işaretleyin.
+3. **Log Analysis** – hata desenleri veya performans metrikleri için HTML‑formatlı günlükleri tarayın.
+4. **ETL Pipelines** – parser'ı web‑scraped içeriği normalleştiren veri‑alım iş akışlarına entegre edin.
+
+## Performans Düşünceleri
+Büyük HTML koleksiyonlarıyla çalışırken, şu ipuçlarını aklınızda bulundurun:
+- **Optimize regex patterns** – aşırı geri izlemeyi önleyin; mümkün olduğunda atomik gruplar veya sahipli nicelikleyiciler kullanın.
+- **Streamline memory usage** – JVM'nin tamponları hızlıca geri kazanmasını sağlamak için ayrıştırmayı try‑with‑resources bloğuna sarın.
+- **Parallel processing** – çok çekirdekli sunucularda doğrusal ölçeklenme için Java’nın `ForkJoinPool`'unu kullanarak birden fazla belgeyi aynı anda arayın.
+
+## Sık Sorulan Sorular
+
+**S: Regular expression nedir?**
+C: Regular expression (regex), dizeler içinde karakter dizilerini eşleştirmek için kullanılan kısa, desen‑tabanlı bir dildir; doğrulama, arama ve metin işleme için yaygın olarak kullanılır.
+
+**S: GroupDocs.Parser, HTML dışı dosyaları işleyebilir mi?**
+C: Evet, PDF, DOCX, XLSX ve PPTX dahil 70'ten fazla formatı destekler; böylece aynı arama mantığı çeşitli belge türlerinde çalışır.
+
+**S: Ayrıştırma hatalarını nasıl ele almalı?**
+C: Ayrıştırma kodunu bir try‑catch bloğuna sarın, `ParserException` yakalayarak sorunu kaydedin ve kaynakların kapatıldığından emin olun.
+
+**S: Regex'im sonuç döndürmüyor—ne yanlış?**
+C: Kaçış karakterleri için deseni iki kez kontrol edin, büyük/küçük harf duyarlılığı ayarlarını doğrulayın ve hedef metnin gerçekten HTML kaynağında bulunduğunu teyit edin.
+
+**S: HTML dosyaları için bir boyut sınırlaması var mı?**
+C: GroupDocs.Parser, 2 GB'a kadar dosyaları işleyebilir; çok büyük HTML dosyaları için bölmeyi veya bölümleri akış olarak işlemeyi, bellek kısıtlamaları içinde kalmak için düşünün.
+
+## Sonuç
+Bu rehberi izleyerek, GroupDocs.Parser for Java içinde yerleşik güçlü bir regex motoru kullanarak **how to search html** belgelerini nasıl arayacağınızı artık biliyorsunuz. Desenleri hızlıca bulabilir, anlamlı verileri çıkarabilir ve çözümü daha büyük Java uygulamaları veya veri akışlarına entegre edebilirsiniz.
+
+**Sonraki Adımlar:** daha karmaşık desenlerle deneme yapın, birden fazla `SearchOptions` birleştirin veya parser'ı talep üzerine metin çıkarımı için bir Spring Boot mikro hizmetine gömün.

+# Xử lý PDF bằng Java: Tìm kiếm & Đánh dấu với GroupDocs
+
+Bạn có bao giờ cảm thấy mình bị ngập trong một biển tài liệu—PDF, file Word, hoặc các định dạng khác—và mong muốn có thể dễ dàng tìm thấy các từ hoặc cụm từ cụ thể? **Java PDF processing** giúp điều đó trở thành hiện thực. Trong hướng dẫn này, bạn sẽ học cách tìm kiếm văn bản trong PDF và tạo các đoạn trích được đánh dấu bằng **GroupDocs.Parser for Java**. Dù bạn đang xây dựng công cụ phân tích tài liệu hay tự động hoá quy trình xem xét nội dung, các bước dưới đây cung cấp giải pháp rõ ràng, sẵn sàng cho môi trường sản xuất.
+
+## Câu trả lời nhanh
+- **Thư viện nào xử lý tìm kiếm văn bản PDF trong Java?** GroupDocs.Parser for Java.
+- **Tôi có cần giấy phép cho việc phát triển không?** Giấy phép tạm thời hoạt động cho việc thử nghiệm; giấy phép đầy đủ cần thiết cho môi trường sản xuất.
+- **Tôi có thể đánh dấu nhiều lần xuất hiện cùng một lúc không?** Có — đặt bán kính đánh dấu và lặp lại các kết quả.
+- **Tìm kiếm có phân biệt chữ hoa chữ thường không?** Mặc định không phân biệt; bạn có thể chuyển đổi qua `SearchOptions`.
+- **Các định dạng nào được hỗ trợ?** Hơn 50 định dạng đầu vào và đầu ra, bao gồm PDF, DOCX, XLSX, PPTX, HTML và hình ảnh.
+
+## Java PDF processing là gì?
+`Java PDF processing` là tập hợp các thao tác lập trình—như trích xuất, tìm kiếm và đánh dấu văn bản—được thực hiện trên các tệp PDF bằng các thư viện Java. Với GroupDocs.Parser, bạn có thể tìm kiếm bất kỳ tài liệu nào được hỗ trợ, lấy ngữ cảnh xung quanh và áp dụng các đánh dấu trực quan, mà không cần mở tệp trong trình xem. Khả năng này cho phép bạn xây dựng các kho lưu trữ nhanh, có thể tìm kiếm và các pipeline tự động kiểm tra mở rộng tới hàng ngàn trang mỗi tài liệu.
+
+## Tại sao nên sử dụng GroupDocs.Parser cho java pdf processing?
+GroupDocs.Parser hỗ trợ **hơn 50 định dạng tệp** và có thể xử lý **PDF hàng trăm trang** mà không cần tải toàn bộ tệp vào bộ nhớ, giảm mức sử dụng RAM lên tới **70 %** so với các cách tiếp cận đơn giản. Công cụ tìm kiếm của nó trả về các offset chính xác, cho phép bạn xây dựng các đánh dấu UI tùy chỉnh hoặc xuất kết quả sang các hệ thống khác. Thư viện được duy trì tích cực, tương thích với Java 8+, và cung cấp cả artifact Maven và Gradle để tích hợp dễ dàng.
+
+## Yêu cầu
+Trước khi bắt tay vào, hãy chắc chắn rằng bạn đã chuẩn bị đầy đủ các yếu tố sau:
+
+- **Môi trường phát triển Java**: JDK 8+ đã được cài đặt.
+- **Maven hoặc Gradle**: Để quản lý phụ thuộc và thiết lập dự án.
+- **Thư viện GroupDocs.Parser for Java**: Tải xuống hoặc thêm qua phụ thuộc.
+- **Tài liệu mẫu**: PDF hoặc văn bản để thử nghiệm tìm kiếm.
+- **Kiến thức cơ bản về Java**: Quen thuộc với lớp, phương thức và xử lý tệp.
+
+Nếu bạn chưa có thư viện, có thể tải phiên bản mới nhất từ [GroupDocs Downloads](https://releases.groupdocs.com/parser/java/) hoặc thêm qua Maven:
+
+```xml
+
+ com.groupdocs
+ groupdocs-parser
+ 21.12
+
+```
+
+## Nhập các gói
+Để bắt đầu, hãy nhập các lớp cần thiết từ GroupDocs.Parser:
+
+`Parser` là lớp chính dùng để tải và tương tác với tài liệu. `HighlightOptions` cấu hình cách văn bản khớp được đánh dấu. `SearchOptions` định nghĩa hành vi tìm kiếm như phân biệt chữ hoa chữ thường. `SearchResult` đại diện cho một kết quả khớp riêng lẻ trong tài liệu.
+
+```java
+import com.groupdocs.parser.Parser;
+import com.groupdocs.parser.search.HighlightOptions;
+import com.groupdocs.parser.search.SearchOptions;
+import com.groupdocs.parser.search.SearchResult;
+```
+
+Các import này bao phủ các chức năng cốt lõi để phân tích tài liệu, thiết lập tùy chọn đánh dấu và thực hiện các thao tác tìm kiếm.
+
+## Quy trình tìm kiếm và đánh dấu hoạt động như thế nào?
+Tải PDF của bạn, cấu hình một đối tượng `HighlightOptions`, thực thi `parser.search`, sau đó lặp qua bộ sưu tập `SearchResult` để tạo các đoạn trích được đánh dấu. Toàn bộ quá trình diễn ra theo hai bước: đầu tiên, parser đọc cấu trúc tài liệu; thứ hai, công cụ tìm kiếm quét luồng văn bản áp dụng các tùy chọn bạn đã định nghĩa. Cách tiếp cận này đảm bảo hiệu năng cao ngay cả với các tệp lớn.
+
+## Hướng dẫn từng bước để tìm kiếm văn bản với đánh dấu
+Hãy cùng đi qua quy trình được chia thành các bước rõ ràng, dễ quản lý. Mỗi bước có phần giải thích riêng để bạn hiểu tại sao và như thế nào.
+
+### Bước 1: Khởi tạo Parser với tài liệu của bạn
+**Điều gì đang xảy ra ở đây?**
+Tạo một thể hiện của lớp `Parser` gắn với tệp tài liệu của bạn cho phép bạn truy cập và phân tích nội dung của nó.
+
+`Parser` tải tài liệu và cung cấp các phương thức để trích xuất và tìm kiếm văn bản.
+
+```java
+try (Parser parser = new Parser("path/to/your/document.pdf")) {
+ // your code here
+}
+```
+
+**Thực tế:**
+Câu lệnh `try-with-resources` đảm bảo tệp của bạn được đóng đúng cách sau khi xử lý, ngăn ngừa rò rỉ tài nguyên. Thay `"path/to/your/document.pdf"` bằng đường dẫn hoặc URL chính xác của bạn.
+
+### Bước 2: Thiết lập tùy chọn đánh dấu
+**Tại sao cần định nghĩa tùy chọn đánh dấu?**
+Bạn có thể muốn kiểm soát cách hiển thị hoặc hành vi của các kết quả tìm kiếm được đánh dấu—ví dụ số ký tự hiển thị quanh khớp hoặc màu sắc (nếu hỗ trợ).
+
+Trong ví dụ này, chúng ta đặt bán kính đánh dấu là 15 ký tự:
+
+`HighlightOptions` chỉ định bán kính ngữ cảnh và các thiết lập trực quan cho các kết quả tìm kiếm được đánh dấu.
+
+```java
+HighlightOptions highlightOptions = new HighlightOptions(15);
+```
+
+Điều này bao bọc văn bản tìm được bằng ngữ cảnh xung quanh—giống như một kính lúp quanh từ khóa—giúp bạn dễ dàng nhận ra vị trí các khớp.
+
+### Bước 3: Thực hiện tìm kiếm trong tài liệu
+**Quy trình tìm kiếm hoạt động như thế nào?**
+Sử dụng `parser.search`, bạn chỉ định từ khóa hoặc cụm từ, các tùy chọn tìm kiếm, và nhận được một tập hợp các đối tượng `SearchResult` có thể lặp.
+
+`SearchOptions` cấu hình các tham số tìm kiếm như phân biệt chữ hoa chữ thường. `SearchResult` chứa chi tiết của mỗi khớp, bao gồm văn bản khớp và vị trí của nó.
+
+```java
+Iterable results = parser.search("lorem", new SearchOptions(true, false, false, highlightOptions));
+```
+
+Phân tích hàm khởi tạo `SearchOptions`:
+
+- `true`: Bật tìm kiếm không phân biệt chữ hoa chữ thường.
+- `false`: Không chỉ khớp toàn bộ từ.
+- `false`: Không tìm kiếm theo mẫu regex.
+- `highlightOptions`: Truyền cấu hình đánh dấu của chúng tôi.
+
+Cấu hình này tìm tất cả các lần xuất hiện của `"lorem"`, bỏ qua chữ hoa chữ thường, và tạo các đoạn trích được đánh dấu.
+
+### Bước 4: Xử lý hỗ trợ tìm kiếm và kết quả
+**Kiểm tra xem tìm kiếm có được hỗ trợ không**
+Một số định dạng có thể không hỗ trợ tìm kiếm — luôn xác nhận:
+
+`parser.isSearchSupported()` trả về một giá trị boolean cho biết định dạng tài liệu đã tải có cho phép tìm kiếm văn bản hay không.
+
+```java
+if (results == null) {
+ System.out.println("Search isn't supported in this document format.");
+ return;
+}
+```
+
+**Xử lý mỗi kết quả tìm kiếm**
+Lặp qua các kết quả để trích xuất và hiển thị các đoạn trích khớp có đánh dấu:
+
+`SearchResult` cung cấp truy cập tới cụm từ khớp và ngữ cảnh xung quanh.
+
+```java
+for (SearchResult result : results) {
+ String snippet = String.format("%s%s%s",
+ result.getLeftHighlightItem().getText(),
+ result.getText(),
+ result.getRightHighlightItem().getText());
+ System.out.println(snippet);
+}
+```
+
+## Các vấn đề thường gặp và giải pháp
+| Vấn đề | Nguyên nhân | Giải pháp |
+|-------|------------|----------|
+| **Không có kết quả trả về** | Định dạng tài liệu không hỗ trợ tìm kiếm | Xác minh `parser.isSearchSupported()` trả về `true`. |
+| **Bán kính đánh dấu có vẻ quá nhỏ** | Bán kính mặc định là 10 ký tự | Tăng bán kính trong `HighlightOptions` (ví dụ, `new HighlightOptions(20)`). |
+| **Lỗi hết bộ nhớ khi xử lý PDF lớn** | Toàn bộ tệp được tải vào bộ nhớ | Sử dụng `Parser` ở chế độ streaming hoặc xử lý tệp theo từng phần; GroupDocs.Parser đã hỗ trợ streaming hiệu quả cho các tệp lớn. |
+| **Phân biệt chữ hoa chữ thường không hoạt động như mong đợi** | Cờ `caseSensitive` được đặt sai | Đảm bảo `SearchOptions(true, …)` đặt đúng giá trị boolean cho việc không phân biệt chữ hoa chữ thường. |
+
+## Câu hỏi thường gặp
+**Q: Tôi có thể tìm kiếm nhiều từ khóa cùng lúc không?**
+A: Không trực tiếp; bạn cần lặp qua từng từ khóa hoặc xây dựng một mẫu regex để khớp tất cả các từ mong muốn.
+
+**Q: Bán kính đánh dấu có ảnh hưởng tới tất cả các định dạng tài liệu không?**
+A: Đối với hầu hết các định dạng được hỗ trợ, bán kính hoạt động đồng nhất; một số định dạng dựa trên hình ảnh sẽ bỏ qua vì chúng không có lớp văn bản gốc.
+
+**Q: Tôi có thể thay đổi màu sắc của đánh dấu không?**
+A: `HighlightOptions` chỉ điều khiển bán kính ngữ cảnh; màu sắc trực quan phụ thuộc vào trình xem PDF mà bạn sử dụng để hiển thị, không phải parser.
+
+**Q: Tìm kiếm có phân biệt chữ hoa chữ thường theo mặc định không?**
+A: Không. Bằng cách đặt `caseSensitive` thành `false` trong `SearchOptions`, tìm kiếm sẽ không phân biệt chữ hoa chữ thường.
+
+**Q: Điều này có hoạt động với hình ảnh đã quét hay chỉ với các tệp dựa trên văn bản?**
+A: Tìm kiếm hoạt động trên các tài liệu có văn bản. Đối với hình ảnh đã quét, bạn cần khả năng OCR, mà GroupDocs OCR cung cấp như một mô-đun riêng.

+# Cách Sử Dụng Regex Để Tìm Kiếm Văn Bản EPUB Với GroupDocs.Parser
+
+Trong hướng dẫn thực hành này, bạn sẽ khám phá **cách sử dụng regex** để tìm kiếm văn bản trong các tệp EPUB bằng GroupDocs.Parser cho Java. Cho dù bạn đang xây dựng một công cụ lập chỉ mục thư viện số hoặc cần xác định các cụm từ cụ thể trên hàng ngàn e‑book, việc thành thạo tìm kiếm bằng biểu thức chính quy sẽ tiết kiệm thời gian và cải thiện độ chính xác. Chúng tôi sẽ hướng dẫn qua quá trình cài đặt, các lớp chính, và các mẫu thực tế, đồng thời đề cập đến **cách tìm kiếm epub** một cách hiệu quả.
+
+## Câu trả lời nhanh
+- **Thư viện nào phân tích EPUB trong Java?** GroupDocs.Parser for Java.
+- **Bạn có thể sử dụng regex để tìm kiếm EPUB không?** Có – API chấp nhận các đối tượng Java Pattern.
+- **Làm thế nào để thực hiện tìm kiếm phân biệt chữ hoa chữ thường?** Đặt `SearchOptions.setIgnoreCase(false)`.
+- **Tôi có cần giấy phép không?** Bản dùng thử miễn phí hoạt động cho việc thử nghiệm; giấy phép đầy đủ loại bỏ các giới hạn.
+- **Phiên bản Java nào được yêu cầu?** JDK 8 hoặc cao hơn.
+
+## GroupDocs.Parser là gì?
+GroupDocs.Parser là một thư viện Java giúp trích xuất văn bản, hình ảnh và siêu dữ liệu từ hơn 50 định dạng tài liệu, bao gồm EPUB. Nó cung cấp lớp `Parser` cấp cao giúp trừu tượng hoá việc xử lý tệp, cho phép bạn tập trung vào logic tìm kiếm thay vì việc phân tích cấp thấp. Thư viện truyền dữ liệu một cách hiệu quả, hỗ trợ môi trường hạn chế bộ nhớ, và cung cấp khả năng tìm kiếm tích hợp hoạt động trực tiếp trên văn bản đã phân tích.
+
+## Tại sao nên sử dụng Regex với GroupDocs.Parser cho EPUB?
+- **Hỗ trợ đa định dạng:** Xử lý hơn 50 định dạng đầu vào, bao gồm EPUB, mà không cần bộ chuyển đổi bên ngoài.
+- **Xử lý tiết kiệm bộ nhớ:** Truyền dữ liệu, cho phép tìm kiếm các EPUB có hàng trăm trang mà không cần tải toàn bộ tệp vào RAM.
+- **Khớp mẫu chính xác:** Regex cho phép bạn xác định từ, cụm từ hoặc các mẫu phức tạp (ví dụ: ngày tháng, ISBN) trong một lần gọi.
+
+## Yêu cầu trước
+- **Java Development Kit (JDK) 8+** đã được cài đặt và cấu hình trong IDE hoặc công cụ xây dựng của bạn.
+- **GroupDocs.Parser for Java** library (có sẵn qua Maven hoặc tải trực tiếp).
+- Kiến thức cơ bản về cú pháp Java và các khái niệm biểu thức chính quy.
+
+## Cách Sử Dụng Regex Để Tìm Kiếm Văn Bản Trong Các Tệp EPUB?
+Tải EPUB của bạn bằng `new Parser("book.epub")` và gọi `search` bằng một `Pattern` đã biên dịch. Cách tiếp cận hai bước này tách riêng việc tải tệp và thực thi mẫu, đảm bảo hiệu năng tối ưu ngay cả với bộ sưu tập lớn.
+
+### Bước 1: Khởi tạo Parser
+Lớp `Parser` là điểm vào để tải và xử lý một tệp EPUB.
+```java
+// ```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/parser/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5
+
+
+```
+```
+
+### Bước 2: Xây dựng một mẫu Regex
+Lớp `Pattern` của Java biên dịch biểu thức chính quy. Ví dụ, để tìm bất kỳ từ nào bắt đầu bằng “list” sau một ký tự khoảng trắng, sử dụng `\\slist\\w*`.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+// Initialize Parser object with an EPUB file path
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.epub")) {
+ // Your code here
+}
+```
+```
+
+### Bước 3: Cấu hình Search Options
+`SearchOptions` cấu hình cách thức tìm kiếm hoạt động, chẳng hạn như độ nhạy chữ hoa/chữ thường và tìm kiếm mờ.
+```java
+// ```java
+import com.groupdocs.parser.Parser;
+
+String epubFilePath = "YOUR_DOCUMENT_DIRECTORY/sample.epub";
+
+try (Parser parser = new Parser(epubFilePath)) {
+ // Further processing steps go here
+}
+```
+```
+
+### Bước 4: Thực hiện tìm kiếm
+`SearchResult` đại diện cho một kết quả khớp, bao gồm văn bản, số trang và vị trí ký tự.
+```java
+// ```java
+String regexPattern = \\slist; // Matches any word preceded by whitespace and 'list'
+```
+```
+
+### Bước 5: Xử lý kết quả
+Duyệt qua tập hợp `SearchResult` để ghi lại các khớp, lưu chúng vào cơ sở dữ liệu, hoặc kích hoạt các quy trình downstream như lập chỉ mục hoặc cảnh báo.
+```java
+// ```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options for search
+SearchOptions options = new SearchOptions(true /* case match */, false /* whole word */, true /* fuzzy */);
+```
+```
+
+## Cách Thực hiện Tìm kiếm Phân biệt Chữ hoa Chữ thường trong Java?
+Đặt `SearchOptions.setIgnoreCase(false)` để buộc thực hiện khớp chính xác theo chữ hoa/chữ thường. Điều này rất quan trọng khi tìm kiếm các định danh, đoạn mã, hoặc tên thương hiệu cần giữ nguyên dạng chữ.
+
+## Các trường hợp sử dụng phổ biến
+1. **Lập chỉ mục Thư viện số:** Tự động tạo các chỉ mục có thể tìm kiếm cho hàng ngàn tiêu đề EPUB.
+2. **Quản lý nội dung:** Xác định các phần chủ đề (ví dụ: “Chapter 5”) trên nhiều cuốn sách để nghiên cứu.
+3. **Khai thác dữ liệu:** Trích xuất các thực thể có cấu trúc như ISBN, ngày tháng hoặc tên tác giả bằng các mẫu regex tùy chỉnh.
+4. **Tích hợp E‑Learning:** Nâng cao nền tảng khóa học với khả năng tìm kiếm toàn văn tức thời cho tài liệu PDF và EPUB.
+
+## Mẹo hiệu năng
+- **Tối ưu mẫu regex:** Ưu tiên các lớp ký tự đơn giản hơn là các cấu trúc gây back‑tracking nặng để giảm tải CPU.
+- **Chia nhỏ EPUB lớn:** Xử lý từng chương riêng biệt nếu tệp vượt quá 200 MB để tránh tăng đột biến bộ nhớ.
+- **Lưu trữ truy vấn thường dùng:** Lưu kết quả của các mẫu phổ biến (ví dụ: từ khóa chung) trong một bản đồ bộ nhớ nhẹ.
+
+## Câu hỏi thường gặp
+
+**Q: Sự khác nhau giữa `search` và `extractText` là gì?**
+A: `search` áp dụng một mẫu regex và chỉ trả về các đoạn khớp, trong khi `extractText` trả về toàn bộ nội dung tài liệu mà không lọc.
+
+**Q: Tôi có thể tìm kiếm nhiều tệp EPUB trong một lần gọi không?**
+A: Không có một API duy nhất xử lý batch, nhưng bạn có thể lặp qua danh sách tệp, tái sử dụng cùng một `Pattern` và `SearchOptions` cho mỗi tệp.
+
+**Q: Tìm kiếm mờ hoạt động như thế nào?**
+A: Bật chế độ fuzzy trong `SearchOptions` để cho phép khoảng cách Levenshtein lên tới hai phép chỉnh sửa, giúp bắt các lỗi chính tả và biến thể nhẹ.
+
+**Q: Có giới hạn kích thước tài liệu không?**
+A: GroupDocs.Parser có thể xử lý EPUB lên tới 500 MB; các tệp lớn hơn nên được chia nhỏ hoặc truyền dữ liệu thủ công.
+
+**Q: Tôi có cần giấy phép cho việc phát triển không?**
+A: Bản dùng thử miễn phí cung cấp đầy đủ quyền truy cập API kèm watermark sử dụng; giấy phép vĩnh viễn loại bỏ các hạn chế và cấp quyền thương mại.

+- **Hiệu năng tôi có thể mong đợi là gì?** GroupDocs.Parser processes 500‑page HTML files in under 2 seconds on a typical server.
+
+## “how to search html” với regex là gì?
+**“How to search html”** đề cập đến việc sử dụng biểu thức chính quy để xác định các mẫu văn bản bên trong mã HTML. Kỹ thuật này cho phép bạn xác định chính xác các từ, số hoặc thẻ tùy chỉnh mà không cần phân tích toàn bộ cây DOM. Bằng cách áp dụng regex trực tiếp lên nguồn HTML thô, các nhà phát triển có thể nhanh chóng trích xuất dữ liệu cụ thể, xác thực nội dung, hoặc lọc các phần, tạo nên một giải pháp nhẹ hơn so với việc phân tích DOM đầy đủ.
+
+## Tại sao nên sử dụng GroupDocs.Parser cho Java cho các tìm kiếm regex?
+GroupDocs.Parser hỗ trợ **70+** định dạng đầu vào và đầu ra—bao gồm HTML, DOCX, XLSX và PDF—trong khi xử lý các tài liệu hàng trăm trang mà không cần tải toàn bộ tệp vào bộ nhớ. Lớp `SearchOptions` gốc của nó cho phép bạn bật biểu thức chính quy, kiểm soát độ nhạy cảm chữ hoa/thường, và giới hạn kết quả, mang lại quá trình quét nhanh và tiết kiệm bộ nhớ.
+
+## Các yêu cầu trước
+Trước khi bắt đầu, hãy chắc chắn rằng bạn đã có:
+
+1. **GroupDocs.Parser for Java** (phiên bản mới nhất, ví dụ, 25.5 hoặc mới hơn).
+2. **Java Development Kit** 8 hoặc mới hơn đã được cài đặt và cấu hình trong IDE của bạn.
+3. Kiến thức cơ bản về **Java regex syntax** (ví dụ, `\d+`, `\bSub\w*`).
+
+## Cài đặt GroupDocs.Parser cho Java
+Để bắt đầu, thêm phụ thuộc Maven vào `pom.xml` của bạn:
+
+```xml
+
+ com.groupdocs
+ groupdocs-parser
+ 25.5

+- **Temporary License** – yêu cầu một khóa thử nghiệm mở rộng từ [GroupDocs' website](https://purchase.groupdocs.com/temporary-license/).
+- **Purchase** – mua giấy phép đầy đủ để sử dụng không giới hạn trong môi trường sản xuất.
+
+**Khởi tạo**
+Sau khi thư viện được thêm vào, khởi tạo ứng dụng Java của bạn để sử dụng GroupDocs.Parser:
+
+```java
+import com.groupdocs.parser.Parser;
+
+public class SetupExample {
+ public static void main(String[] args) {
+ String filePath = "path/to/your/document.html";
+ try (Parser parser = new Parser(filePath)) {
+ // Initialization complete, ready to parse and search!
+ } catch (Exception e) {
+ e.printStackTrace();
+ }
+ }
+}
+```
+
+## Cách Tìm Kiếm HTML Bằng GroupDocs.Parser cho Java?
+Tải tệp HTML của bạn bằng lớp `Parser` và thực hiện tìm kiếm regex chỉ trong hai dòng mã. Lớp `Parser` là điểm vào để đọc và phân tích các loại tài liệu được hỗ trợ, cung cấp các phương thức để trích xuất văn bản và tìm kiếm. Bằng cách cấu hình `SearchOptions`, bạn chỉ định cho parser xử lý mẫu của bạn như một biểu thức chính quy, tùy chọn bật tìm kiếm phân biệt chữ hoa/thường hoặc khớp toàn bộ từ.
+
+### Triển khai từng bước
+
+### Bước 1: Định nghĩa mẫu biểu thức chính quy của bạn
+Đầu tiên, tạo mẫu regex phù hợp với văn bản bạn cần. Trong ví dụ này, chúng ta tìm các từ bắt đầu bằng **“Sub”** tiếp theo là một chữ số (ví dụ, `Sub1`, `Sub9`).
+
+```java
+String regexPattern = "Sub[0-9]";
+```
+
+### Bước 2: Thiết lập tùy chọn tìm kiếm
+`SearchOptions` là một đối tượng cấu hình xác định hành vi tìm kiếm như chế độ regex và độ nhạy cảm chữ hoa/thường.
+Cấu hình đối tượng `SearchOptions` để kích hoạt chế độ regex, đặt độ nhạy cảm chữ hoa/thường, và quyết định có khớp toàn bộ từ hay không. `SearchOptions` là một bộ giữ cấu hình cho parser biết cách thực hiện tìm kiếm.
+
+```java
+import com.groupdocs.parser.options.SearchOptions;
+
+// Configure options: case-sensitive, whole word, use regex
+SearchOptions options = new SearchOptions(true, false, true);
+```
+
+### Bước 3: Thực hiện tìm kiếm
+Gọi phương thức `search` trên một thể hiện `Parser`, truyền vào đường dẫn tệp HTML, mẫu regex và các tùy chọn. Phương thức trả về một tập hợp các đối tượng `SearchResult`, mỗi đối tượng chứa văn bản khớp và vị trí của nó trong tài liệu.
+
+```java
+import com.groupdocs.parser.data.SearchResult;
+
+try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.html")) {
+ Iterable results = parser.search(regexPattern, options);
+
+ for (SearchResult result : results) {
+ System.out.println(String.format("At %d: %s", result.getPosition(), result.getText()));
+ }
+} catch (Exception e) {
+ e.printStackTrace();
+}
+```
+
+**Các tùy chọn cấu hình chính**
+- **Case Sensitivity** – đặt `true` để khớp chính xác chữ hoa/thường.
+- **Whole Word Search** – `false` bao gồm các khớp một phần.
+- **Use Regular Expressions** – phải là `true` để bật xử lý regex.
+
+## Các vấn đề thường gặp và giải pháp
+- **Incorrect file path** – kiểm tra lại xem tệp HTML có thể truy cập được từ thư mục làm việc của ứng dụng không.
+- **Invalid regex syntax** – kiểm tra mẫu của bạn bằng công cụ kiểm tra regex trực tuyến trước khi nhúng vào mã.
+- **Memory leaks** – luôn luôn đóng thể hiện `Parser` hoặc sử dụng try‑with‑resources để đảm bảo các luồng được giải phóng.
+
+## Ứng dụng thực tiễn
+Việc sử dụng tìm kiếm dựa trên regex trong HTML mở ra nhiều kịch bản thực tế:
+
+1. **Data Extraction** – trích xuất số hoá đơn, ID hoặc dấu thời gian từ các báo cáo HTML hàng loạt.
+2. **Content Filtering** – tự động loại bỏ hoặc đánh dấu các phần chứa từ khóa bị cấm.
+3. **Log Analysis** – quét các log định dạng HTML để tìm mẫu lỗi hoặc chỉ số hiệu suất.
+4. **ETL Pipelines** – tích hợp parser vào quy trình nhập dữ liệu để chuẩn hoá nội dung thu thập từ web.
+
+## Các yếu tố hiệu năng
+Khi xử lý các tập hợp HTML lớn, hãy lưu ý những lời khuyên sau:
+
+- **Optimize regex patterns** – tránh backtracking quá mức; sử dụng nhóm nguyên tử hoặc quantifier sở hữu khi có thể.
+- **Streamline memory usage** – bao bọc quá trình phân tích trong khối try‑with‑resources để JVM giải phóng bộ đệm kịp thời.
+- **Parallel processing** – tận dụng `ForkJoinPool` của Java để tìm kiếm nhiều tài liệu đồng thời, mở rộng tuyến tính trên các máy chủ đa lõi.
+
+## Câu hỏi thường gặp
+
+**Q: Biểu thức chính quy là gì?**
+A: Biểu thức chính quy (regex) là một ngôn ngữ ngắn gọn, dựa trên mẫu để khớp các chuỗi ký tự trong chuỗi, được sử dụng rộng rãi cho việc xác thực, tìm kiếm và thao tác văn bản.
+
+**Q: GroupDocs.Parser có thể xử lý các tệp không phải HTML không?**
+A: Có, nó hỗ trợ hơn 70 định dạng—bao gồm PDF, DOCX, XLSX và PPTX—do đó cùng một logic tìm kiếm hoạt động trên nhiều loại tài liệu khác nhau.
+
+**Q: Tôi nên xử lý lỗi phân tích như thế nào?**
+A: Bao bọc mã phân tích trong khối try‑catch, bắt `ParserException` để ghi lại sự cố và đảm bảo các tài nguyên được đóng.
+
+**Q: Regex của tôi không trả về kết quả—có vấn đề gì?**
+A: Kiểm tra lại mẫu để chắc chắn các ký tự được escape đúng, xác nhận cài đặt độ nhạy cảm chữ hoa/thường, và xác nhận văn bản mục tiêu thực sự tồn tại trong nguồn HTML.
+
+**Q: Có giới hạn kích thước cho tệp HTML không?**
+A: GroupDocs.Parser có thể xử lý các tệp lên tới 2 GB; đối với các tệp HTML cực lớn, hãy cân nhắc chia nhỏ chúng hoặc stream các phần để giữ trong giới hạn bộ nhớ.
+
+## Kết luận
+Bằng cách làm theo hướng dẫn này, bạn đã biết **how to search html** tài liệu bằng một engine regex mạnh mẽ được tích hợp trong GroupDocs.Parser cho Java. Bạn có thể nhanh chóng xác định các mẫu, trích xuất dữ liệu có ý nghĩa, và tích hợp giải pháp này vào các ứng dụng Java lớn hơn hoặc các pipeline dữ liệu.
+
+**Next Steps:** thử nghiệm các mẫu phức tạp hơn, kết hợp nhiều `SearchOptions`, hoặc nhúng parser vào một microservice Spring Boot để trích xuất văn bản theo yêu cầu.
