Subject [jira] [Commented] (LUCENE-6388) Optimize SpanNearQuery
Date Thu, 02 Apr 2015 15:28:53 GMT

Paul Elschot commented on LUCENE-6388:
--------------------------------------

Oops, I thought by now ArrayList would be JIT-ed away, thanks.
Also the UOE's in the NearSpansOrdered payload methods have gone in this patch, I had put
these in to check the tests.

> 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.
