[jira] [Comment Edited] (SOLR-9027) Add GraphTermsQuery to limit
traversal on high frequency nodes
[ https://issues.apache.org/jira/browse/SOLR-9027?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15254155#comment-15254155 ]

---------------------------------------------------------------
Basic implementation. Tests still needed.
It doesn't do anything fancy to build up the matching docs. The main thing that it adds is the maxDocFreq param which is the threshold for discarding query terms.
This essentially creates an on-the-fly stop list for high frequency nodes that appear during a graph traversal.

> 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.
