Robert Muir commented on LUCENE-5694:
-------------------------------------
If you disable BS1 in luceneutil, it will appear this patch gives a speedup,
but from my investigation this is just trickery.
I did further benchmarking to hone in and its just the same speed.
But it can be beneficial in cases where score() is not called
(ConstantScoreQuery, constructing a filter, when there are multiple prohibited
clauses, etc etc)
> Fix Disjunction*Scorer not to score unless you ask it to

> These things scored implicitly on next()/advance() for historical reasons:
> but now that minShouldMatch is split apart we should remove this, its
> unnecessary.
> This allows us to remove the horrendous afterNext and clean things up, too.
