Subject [jira] [Created] (LUCENE-6388) Optimize SpanNearQuery
Date Thu, 02 Apr 2015 06:21:53 GMT
Robert Muir created LUCENE-6388:
-----------------------------------

             Summary: Optimize SpanNearQuery
                 Key: LUCENE-6388
                 URL: https://issues.apache.org/jira/browse/LUCENE-6388
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Robert Muir


After the big spans overhaul in LUCENE-6308, we can speed up SpanNearQuery a little more:

* SpanNearQuery defaults to collectPayloads=true, but this requires a slower implementation,
for an uncommon case. Use the faster no-payloads impl if the field doesn't actually have any
payloads.
* Use a simple array of Spans rather than List in NearSpans classes. This is iterated over
often in the logic.
