[jira] [Resolved] (LUCENE-7520) WeightedSpanTermExtractor should not rewrite MultiTermQuery all the time

     [ https://issues.apache.org/jira/browse/LUCENE-7520?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

David Smiley resolved LUCENE-7520.
----------------------------------
       Resolution: Fixed
    Fix Version/s: 6.3

Thanks Dat!

I tweaked the early-return logic to happen a bit earlier to avoid the needless invocation of getLeafReader() which can be rather expensive (sometimes needing to index the content).

I put the CHANGES.txt entry into "Improvements" because it's debatable if this is a bug fix or an optimization.

> Currently WeightedSpanTermExtractor will rewrite MultiTermQuery regardless of the field being requested for highlighting. In some case like SOLR-2216, It can be costly and cause TooManyClauses exception for no reason.
