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