Subject [jira] [Created] (LUCENE-6756) Give MatchAllDocsQuery a dedicated BulkScorer

------------------------------------

             Summary: Give MatchAllDocsQuery a dedicated BulkScorer
                 Key: LUCENE-6756
                 URL: https://issues.apache.org/jira/browse/LUCENE-6756
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Adrien Grand
            Assignee: Adrien Grand
            Priority: Minor


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.
