Hi Vivek, I don't use Lucene directly, I mostly use Solr so I may be wrong. But I guess you can use IndexSearcher#explain api to return the score explanation. This API should return what all fields and how much they have contributed to the final score. Once you get that information, you can parse that at the client side to know which field contributed most.
