Thank you for the response Paul.
My return search result some times more than 100 also.Currently i am displaying 30 pages per page. In such case, i cannot go for selection as i need to export all the search result documents.
I actually tried to assign the search query to session scope and tried to do the FT search again through java script. But the option for fuzzy search is not working in javascript.
I tried this to perform FT fuzzy search, coll=db.FTSearch(strQuery,0,16384) , the collection as zero.
If i am giving, coll=db.FTSearch(strQuery,0), i am getting the collection
Could you please suggest if any other alternative is there.
