Description

I am currently running the test https://github.com/apache/lucene-solr/blob/trunk/solr/core/src/test/org/apache/solr/request/SimpleFacetsTest.java#L859 on multi shard environment and i notice some discrepancies with facet_range count for after,before, and between tags if the # of shards !=1

Running the query(https://github.com/apache/lucene-solr/blob/trunk/solr/core/src/test/org/apache/solr/request/SimpleFacetsTest.java#L874) on #shards = 1 and matches the expected output

Running the same above on #shards > 1 (facet_range count for after,before,between differs)
