[jira] [Created] (LUCENE-6329) Calling score() should be ok even if needsScores is false

Adrien Grand created LUCENE-6329:
------------------------------------

             Summary: Calling score() should be ok even if needsScores is false
                 Key: LUCENE-6329
                 URL: https://issues.apache.org/jira/browse/LUCENE-6329
             Project: Lucene - Core
          Issue Type: Bug
            Reporter: Adrien Grand
            Assignee: Adrien Grand
            Priority: Minor
             Fix For: Trunk, 5.1


Currently if you use approximations on a disjunction scorer and call score() while needsScores was set to false, then you might run into exceptions.

The reason is that when scores are not needed then the scorer doesn't maintain the list of scorers positioned on the current doc ID and you can eg. end up with exhausted scorers in this list.
