Mike Drob commented on SOLR-14166:
----------------------------------
Can you describe (and give some example queries) about what performed much
better/somewhat better/somewhat worse? I'm not looking for full tables, but
just a general idea of what we give up and what we gained.
Do we need to update the ref guide, especially around
[https://solr.apache.org/guide/8_8/common-query-parameters.html#cache-parameter]
?

> "fq" filter queries that have cache=false and which aren't processed as a
> PostFilter (thus either aren't a PostFilter or have a cost < 100) are
> processed in SolrIndexSearcher using a custom Filter thingy which uses a
> cost-ordered series of DocIdSetIterators. This is not TwoPhaseIterator
> aware, and thus the match() method may be called on docs that ideally would
> have been filtered by lower-cost filter queries.
