> It would be nice to have the possibility to easily sort the shards in the preferred order e.g. by replica type. The attached patch adds support for {{shards.sort}} parameter that allows one to sort e.g. PULL and TLOG replicas first with \{{shards.sort=replicaType:PULL|TLOG }}(which would mean that NRT replicas wouldn't be hit with queries unless they're the only ones available) and/or to sort by replica location (like preferLocalShards=true but more versatile).
