Subject [jira] [Commented] (SOLR-9027) Add GraphTermsQuery to limit traversal on high frequency nodes
Date Thu, 28 Apr 2016 02:14:12 GMT


Kevin Watters commented on SOLR-9027:

no specific use case.. but if doc frequency is 0 for a given term in a "node/from" field,
 there's not much point in traversing it,or querying for it in the first place.   I'm not
sure if that's even possible, but you might have edges that point to a document that doesn't
exist, in such a case, it's an easy optimization to avoid that traversal.   (similar to the
leafNodesOnly parameter on the GraphQuery.)

> 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.
