> Term queries, phrase queries and their combinations through boolean queries
> should not be cached too agressively since they can efficiently make use of
> skip lists. However we also have a number of queries that in practice need to
> visit all matches anyway like PrefixQuery, TermsQuery, PointInSetQuery,
> PointRangeQuery, so caching them more agressively can help avoid computing
> all documents that match in the whole index again and again.
