Hoss Man commented on SOLR-8496:
--------------------------------
Also: does this reproduce for you when indexing from scratch, or is this an
index you originally built with an older version of Solr and then upgraded to
5.4? (trying to figure out if there are older segments and maybe the bug is
specific to 5.4 reading deleted docs from those older segments)
can you also run CheckIndex (command line) and provide all of that output?

> 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.
> We're querying a test scenario with:

> *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.
