--------------------------------------

Kindly try once by *reloading a collection* then attempt to do queries. Hope it solves fluctuate hit count issue.

> Violent shutdown of collection with 2 replicas per shard with heavy ingest causes split-brain where the query results against a collection will yield different results each time.
>   
> Steps to reproduce IPL 2 issue # Deploy a solr cluster with at least 3 instances
>  # Create a solr collection with 3 shards and 2 replicas per shard
>  # Begin heavy ingest to solr
>  # Kill one of the solr instances (we had it running in a docker container, and ran "docker kill" on the container)
>  # Wait for the instance to come back up
>  # Stop ingest to solr
>  # Run a hard commit on the collection
>  # Attempt to do a few queries to the collection
>  
> +*Expected Result:*+ * Every query returns the same hit count
> +*Actual Result:*+ * As you run queries, the hit count will fluctuate
