Greg Miller updated LUCENE-10060:
---------------------------------
    Description: 
We need to make sure DSQ instances don't end up in the query cache. -It's 
important that the {{DrillSidewaysScorer}} (bulk scorer implementation) 
actually runs during query evaluation in order to populate the "sideways" 
{{FacetsCollector}} instances with "near miss" docs. If it gets cached, this 
won't happen.-

There may also be an implication around {{acceptDocs}} getting honored as well. 
[~zacharymorn] may be able to provide more details.

UPDATE: The original issue I detailed above isn't actually an issue since 
{{DrillDownQuery}} doesn't implement {{equals}}, so the cache always misses and 
it always executes the {{BulkScorer}} ( {{DrillSidewaysScorer}} ). Tricky! 
There is a separate issue found by Zach (as mentioned above) related to 
"acceptDocs" though. See below conversation and link off to the separate PR 
conversation for more details.
