Hi Erick, Thank you for the reply. What I meant was suppose I have the config:
2 shards each with 1 replica. Hence, on both servers I have 1. shard1_replica1 2 . shard2_replica1 Suppose I have 50 documents then, shard1_replica1 + shard2_replica1 = 50 ? or shard2_replica1 = 50 && shard1_replica1 = 50 ?
