---------------------------------------------------------------
[~dsmiley], I've been working on the changes you proposed. I dug into how the
TermContext is being used elsewhere in Lucene. What I found was that the
TermQuery is holding onto the TermContext and seems to be relying on wrapper
queries to manage it properly. This is marked as an expert usage. The
CommonTermsQuery uses this constructor. So it does appear that holding onto the
TermContext is OK, as long as it's handled properly. So I'll review just to
make sure the TermContexts are always regenerated when the query is run and
continue to hold onto it within the query.

> The gatherNodes() Streaming Expression is currently using a basic disjunction
> query to perform the traversals. This ticket is to create a specific
> GraphTermsQuery for performing the traversals.
> The GraphTermsQuery will be based off of the TermsQuery, but will also
> include an option for a docFreq cutoff. Terms that are above the docFreq
> cutoff will not be included in the query. This will help users do a more
> precise and efficient traversal.
