Robert Muir commented on LUCENE-6561:
-------------------------------------
I have concerns, there used to be a terms dict cache, and we removed it because
it caused things like concurrency slowdowns and other issues.
Generally speaking I don't think a cache is beneficial...
> Add a TermContextCache to IndexSearcher

> TermContexts can be quite expensive to build, and if you have fairly complex
> queries that re-use the same terms you can end up spending a lot of time
> re-building the same ones over and over again. It would be nice to be able
> to cache them on an IndexSearcher, so that they can be re-used.
