Subject [jira] [Commented] (LUCENE-8304) Add TermFrequencyQuery
Date Thu, 10 May 2018 16:33:00 GMT


Robert Muir commented on LUCENE-8304:

It is inefficient: because it takes as input something like "the" AND freq>50. Currently
this is done like a very-slow conjunction (the index is not used).

Maybe it would help to explain the use-case better for this query.

> This has come up a few times when writing query parsers.  It would be useful to have
a query that returned documents that match a term with a particular frequency - eg, all docs
where "patent" appears at least five times.
