Description

I notice that using facet.mincount in SolrCloud mode with distrib=true fails to filter the facets based on the count. However, the same query with distrib=false works as expected.

• Indexed some data as provided by the upstream test.

• Running in SolrCloud mode with distrib=false (facet.mincount works as expected)
