Adrien Grand updated LUCENE-6330:
---------------------------------
Attachment: LUCENE-6330.patch
Here is a patch, it makes BS1 wrap sub scorers similarly to
ConstantScoreQuery's BulkScorer when scores are not needed so that calling
score on sub scorers (which it does for every document) does not need to eg.
decode norms.
> BooleanScorer should not call score() when scores are not needed

> BooleanScorer (and maybe others?) still call score() when scores are not
> needed. While this does not make results wrong, it is sub-optimal since it
> still forces to decode norms while they are not needed.
