[jira] [Created] (LUCENE-6309) disable coord when scores are not needed, or the scoring fn does not use it

Robert Muir created LUCENE-6309:
-----------------------------------

             Summary: disable coord when scores are not needed, or the scoring fn does not use it
                 Key: LUCENE-6309
                 URL: https://issues.apache.org/jira/browse/LUCENE-6309
             Project: Lucene - Core
          Issue Type: Task
            Reporter: Robert Muir


In BooleanWeight when disableCoord is set, things are nicer. coord makes things complex (e.g. sometimes requires some crazy scorers in BooleanTopLevelScorers) and can block optimizations.

We should also implicitly disableCoord when scores are not needed, or when the Similarity does not use coord().
