[jira] [Commented] (SOLR-9868) RangeFacet : Use DocValues for accs
and docSet collection instead of RangeQuery

SOLR-9868 RangeFacet : Use DocValues for accs and docSet collection instead of RangeQuery
RangeFacet initiates a range query for each range bucket to get the docSet. DocSet later used for accs collection.
For singleValued numeric fields, we can use docValues to find the matching slots for each doc to collect accumulators while iterating over base docSet. If there is a subFacet, docSet per range bucket can be collected from base docSet as well.
Gains :
One iteration over base docSet vs querying over baseDocSet for each range bucket
Memory saving If there is no subFacet, since per bucket docSet is not needed
