+### Search all collections
+
+```cpp
+auto result = client.searchAll({{"q", "research"}, {"limit", "20"}});
+auto selected = client.searchAll({{"q", "research"}, {"collections", "universities,science"}});
+```
+
+`globalSearch` remains available as an equivalent name. Results are globally merged and each hit includes `document._collection`.
