Subject [jira] [Commented] (LUCENE-6513) Allow limits on SpanMultiTermQueryWrapper expansion
Date Mon, 02 Oct 2017 21:53:00 GMT


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.
