Yonik Seeley commented on SOLR-8496:
------------------------------------
The original code was missing the case when liveDocs should be consulted, so I
added a patch that consulted liveDocs only in the case when it was needed (when
all clauses are uncached).
If we want to investigate further code cleanups, I think that can be done in
another issue what won't hold up the releases.

> Our setup is based on multiple cores. In One core we have a multi-filed with
> integer values. and some other unimportant fields. We're using multi-faceting
> for this field.

> *The Problem:*
> In the first query, we're getting a facet count of 4, which is correct. After
> updating one document, we're getting 5 as a result wich is not correct.
