Subject [jira] [Commented] (SOLR-9027) Add GraphTermsQuery to limit traversal on high frequency nodes
Date Wed, 27 Apr 2016 21:50:12 GMT

    [ https://issues.apache.org/jira/browse/SOLR-9027?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15261007#comment-15261007

Kevin Watters commented on SOLR-9027:
-------------------------------------

Nice stuff Joel!  Just a thought, it might be nice to also provide a "maxDocFreq"  on the
GraphTermsQuery...  relatively easy to add now, and it would allow graph traversal that ignore
sparse edges...  

Either way, this is very cool,  It seems like this would be a natural enhancement for the
GraphQuery when it builds the frontier.

> 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.
