Subject [jira] [Created] (LUCENE-6261) TwoPhaseDocIdSetIterator.matches should be called at most once per doc ID

             Summary: TwoPhaseDocIdSetIterator.matches should be called at most once per doc
ID
                 Key: LUCENE-6261
                 URL: https://issues.apache.org/jira/browse/LUCENE-6261
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Adrien Grand
            Assignee: Adrien Grand
            Priority: Minor


We did not document it but TwoPhaseDocIdSetIterator.matches should only be called once per
doc ID. In some cases, running it twice might not work (eg. phrases since the positions would
already be consumed when we try to call matches() on the second time) and in the general case
it would be a performance bug if this method is called several times anyway.
