Nicholas Knize commented on LUCENE-7019:
----------------------------------------
+1
This is great! Some dirty benchmarks indicate a few 100 ms boost in query
performance with the greatest boost on multi-valued queries. I also backported
to 5.4 as this does a better job fixing the multi-valued performance bug than
LUCENE-7018.

> This query today uses an approximation+confirm approach, but it all happens
> when you call scorer(), in a termsEnum loop.
> This causes several problems (even after
> https://issues.apache.org/jira/browse/LUCENE-7018) because it can do too much
> work, if queries have multiple values since the doc can be "confirmed" more
> than once.
> I think it would be better to delay this confirmation as much as possible, so
> that other parts of the query (e.g. other filters, conjunctions, etc) can
> eliminate checks as well.
