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

Doron Cohen commented on LUCENE-912:
------------------------------------

Actually I changed my mind....  (and saw your reply just before clicking "Add" on this comment):

  Taking back my last comment - with Michael's fix there are no extra cycles in the expected
use of score().
  If we try to avoid re-computation in case score() is called twice for same doc, there would
be an additional if() for every call to score().

I think I will take it from here to a new issue and handle these two separately.
