Hi Veda, Lucene doesn't provide such functionality out of the box, but you could use MoreLikeThis ( https://lucene.apache.org/core/7_4_0/queries/org/apache/lucene/queries/mlt/MoreLikeThis.html) to search for similar documents and then compute a finer-grained similarity score on client-side. This would avoid having to compute a similarity score with every document of your collection.
