Subject [jira] Commented: (LUCENE-912) DisjunctionMaxScorer.skipTo has bug that keeps it from skipping

Michael Busch commented on LUCENE-912:
--------------------------------------

Yes I agree. Keeping the score in BooleanScorer until next() or skipTo() is 
called is a good optimization to avoid recomputation. I guess I was just 
curios about the reasons why the tests failed.
