I know there is a built-in DuplicateFilter in Lucene, to deduplicate the results from lucene. This is a very important feature for the users to search on the document database, where duplicating rate is very high.
As I am using Hibernate Search to do the full text index/search, and wondering if there is a way for me bring the DuplicateFilter on Lucene to the Hibernate Search?
It is possible by using filters. See for
BestDriversFilter- it extends org.apache.lucene.search.Filter in the same way as DuplicateFilter.
