how to display related search keywords

[ytkah]

Hi,Bennett,we use your wordpress plugin 'Search Meter',it's very nice,now we want to display some related search keywords in result page,
eg.
I search 'led',somebody had already searched 'led display','led light',now the related search keywords are 'led display','led light',it's depend on the search history

I am planning to update the way searches are recorded. For example, a search for "red blue" will return the same results as "blue red", so I. want to autmatically group related searches somehow.
