[jira] [Created] (LUCENE-6878) TopDocs.merge should use updateTop instead of pop / add

Daniel Jelinski created LUCENE-6878:
---------------------------------------

             Summary: TopDocs.merge should use updateTop instead of pop / add
                 Key: LUCENE-6878
                 URL: https://issues.apache.org/jira/browse/LUCENE-6878
             Project: Lucene - Core
          Issue Type: Improvement
          Components: core/search
    Affects Versions: Trunk
            Reporter: Daniel Jelinski
            Priority: Trivial


The function TopDocs.merge uses PriorityQueue in a pattern: pop, update value (ref.hitIndex++), add. JavaDocs for PriorityQueue.updateTop say that using this function instead should be at least twice as fast.
