Description

SOLR-9432 introduces refinement in JSON Faceting which makes sure all the respective buckets are fetched from each shard of the collection. This ensures authentic mathematical bucket counts.

FacetStream should have refinement as an optional parameter like below, with default being "false":

facet(collection1,
      q="*:*",
      refine="true",
      buckets="a_s",
      bucketSorts="sum(a_i) desc",
      bucketSizeLimit=100,
      sum(a_i),
      count(*))
