------------------------------------
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.
