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.
