Description

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.
