------------------------------------
Summary: Bulk scoring could speed up MUST_NOT clauses
Key: LUCENE-6940
URL: https://issues.apache.org/jira/browse/LUCENE-6940
Project: Lucene - Core
Issue Type: Improvement
Reporter: Adrien Grand
Assignee: Adrien Grand
Priority: Minor
Today when you have MUST_NOT clauses, the ReqExclScorer is used and needs to
check the excluded clauses on every iteration. I suspect we could speed things
up by having a BulkScorer that would advance the excluded clause first and then
tell the required clause to bulk score up to the next excluded document.
