Hi, Thanks Ian for your reply. What i did was to put a check in my indexing such that when the stirng to index is just % it stores it un_analyzed else then analyze and i then use the TermQuery to search for it and it is now working.
Thanks a lot for your tip. Cheers. Ian Lea wrote: > > If you store the field unanalyzed it will be indexed as is.
