[jira] [Created] (LUCENE-6944) BooleanWeight.bulkScorer should not
build any sub bulk scorer if there are required/prohibited clauses
Adrien Grand created LUCENE-6944:
------------------------------------
Summary: BooleanWeight.bulkScorer should not build any sub bulk scorer if there are required/prohibited clauses
Key: LUCENE-6944
URL: https://issues.apache.org/jira/browse/LUCENE-6944
Project: Lucene - Core
Issue Type: Improvement
Reporter: Adrien Grand
Assignee: Adrien Grand
Priority: Minor
BooleanWeight.bulkScorer creates a sub bulk scorer for all clauses until it meets a clause that is not optional (the only kind of clause it can deal with). However the Weight.bulkScorer method is sometimes costly, so BooleanWeight.bulkScorer should first inspect all clauses to see if any of them is not optional to avoid creating costly bulk scorers to only trash them later.
