[jira] [Created] (LUCENE-6391) Give SpanScorer two-phase iterator support.

Robert Muir created LUCENE-6391:
-----------------------------------

             Summary: Give SpanScorer two-phase iterator support.
                 Key: LUCENE-6391
                 URL: https://issues.apache.org/jira/browse/LUCENE-6391
             Project: Lucene - Core
          Issue Type: Bug
            Reporter: Robert Muir


Fix SpanScorer to use any two-phase iterator support of the underlying Spans. This means e.g. a spans in a booleanquery, or a spans with a filter can be faster.

In order to do this, we have to clean up this class a little bit:
* forward most methods directly to the underlying spans.
* ensure positions are only iterated at most once.
