[jira] [Commented] (LUCENE-6513) Allow limits on
SpanMultiTermQueryWrapper expansion
[ https://issues.apache.org/jira/browse/LUCENE-6513?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16188913#comment-16188913 ]
Timothy M. Rodriguez commented on LUCENE-6513:
----------------------------------------------
Apologies for the late alternative implementation. For what it's worth, we've been utilizing this patch for about a year and it's helped improve responsiveness to queries while limiting the expansions.

> SpanMultiTermQueryWrapper currently rewrites to a SpanOrQuery with as many clauses as there are matching terms. It would be nice to be able to limit this in a slightly nicer way than using TopTerms, which for most queries just translates to a lexicographical ordering.
