See the surround query in lucene/contrib. It support proximity search ....query syntax is diff..but you can customize it. By customizing javacc language file-"QueryParser .jj" you can get as you wish.

I have identified the following issues so I would like verification that what the existing rules have do not exist in Lucene or there is a work-around. 1) Teragram uses a Polish Notation for its rules, i.e. Note: DIST_2 is a proximity of within 2 words DIST_2 (OR (phrase1, phrase 2, .... phrase 20) (OR(phrasea, phraseb, phrase c) ) This says "if any phrase in this group is within 2 words of any phrase in the second group". My understanding is proximity in Lucene is only against individual phrases, not between two groups. Is there any way to do the functional equivalent short of "phrase1 phrasea"~2 "phrase1 phraseb"~2 "phrase2 phrasea"~2 "phrase2 phraseb"~2 etc The other question I have is "is there a notion of a sentence such that one could say do these word occur in the same sentence?
