Major Description
This patch is from Rob (I tweaked a bit, removing the numScorers param
to DisjunctionScorer ctor); it eliminates the code dup in the two
DisjunctionScorer subclasses by moving the code up to the base class
... I did a quick perf test on Wikipedia and it looks like hotspot
seems to not mind (NOTE: I hardwired BS2 for both comp and base):
