Michael Busch commented on LUCENE-730:
--------------------------------------

> With this patch the class BooleanWeight is not
> in (direct) use anymore - it is extended by 
> BooleanWeight2 and then only the latter is used, 
> and creates either Scorer2 or Scorer. We could 
> get rid of BolleanWeight2, and have a single 
> class BooleanWeight.

Agree. Will do.

> Javadocs for useScorer14 methods:

This is good! Thanks Doron, I will add the javadocs
to my patch.

> Restore top level disjunction performance
