> This relates to SOLR-8559 -- which improves the algorithm used by fcs faceting when {{facet.mincount=1}}
> This patch allows {{facet.mincount}} to be sent as 1 for distributed queries. As far as I can tell there is no reason to set {{facet.mincount=0}} for refinement purposes . After trying to make sense of all the refinement logic, I cant see how the difference between _no value_ and _value=0_ would have a negative effect.
> *Test perf:*
> - ~15million unique terms
> - query matches ~3million documents
> *Params:*
> {code}
> facet.mincount=1
> facet.limit=500
> facet.method=fcs
> facet.sort=count
> {code}
> *Average Time Per Request:*
> - Before patch:  ~20seconds
> - After patch: <1 second
> *Note*: all tests pass and in my test, the output was identical before and after patch.
