Hi Preetam, Questions like yours are better served in the java-user mailing list, which is devoted to Q&A about *using* Lucene, rather than here in the java-dev list, which is reserved for discussions concerning Lucene's *development*.
In the contrib/ area on the trunk (not yet part of any release), there is a class called ShingleFilter that might be useful to you - here is a link to the nightly javadoc for it: <http://hudson.zones.apache.org/hudson/job/Lucene-trunk/javadoc/contrib-analyzers/org/apache/lucene/analysis/shingle/ShingleFilter.html> If you create a field containing token n-grams (a.k.a. shingles) and use it as a component of your queries, I think you can achieve something similar to what you want.
