Subject [jira] [Commented] (SOLR-9027) Add GraphTermsQuery to limit traversal on high frequency nodes
Date Thu, 28 Apr 2016 02:07:13 GMT


Joel Bernstein commented on SOLR-9027:

Sure, this would be easy to add. I was having a hard time thinking of the use cases though.
Are there scenarios where nodes with low document frequencies are better to skip?

> 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.
