    Description

      DuplicateFilter is a filter which aims at only exposing a single document per unique field value. It has some flaws, for instance it only works if you have a single leaf and we now have a better way to handle this use-case with DiversifiedTopDocsCollector. So I suggest that we just remove it and recommend users to use DiversifiedTopDocsCollector instead.
