    Description

      MatchAllDocsQuery currently uses the default BulkScorer, which creates a Scorer and iterates over matching doc IDs up to NO_MORE_DOCS. I tried to build a dedicated BulkScorer, which seemed to help remove abstractions as it helped improve throughput by a ~2x factor with simple collectors.
