The spaces just came i guess when i copied the code to outlook :-), actually there arent any. Let me take a look at Luke , especially testing to see what should be returned when i run the aprsed query.. sounds very interesting.. Thanks a lot Pramodh

I believe that since you're indexing the fields UN_TOKENIZED, that the spaces are preserved in the query (but I'm not entirely clear on this point, so don't take my word for it completely <G>). Have you used Luke to examine your index? You can also put parsed form of the query into Luke and play around with that to see what *should* work. Google lucene luke and you'll find it right away.
