 p. Control if the operation will be allowed to execute based on the number of active shards within that partition (replication group). The values allowed are @one@, @quorum@, and @all@. The parameter to set it is @consistency@, and it defaults to the node level setting of @action.write_consistency@ which in turn defaults to @quorum@.
 
 p. For example, in a N shards with 2 replicas index, there will have to be at least 2 active shards within the relevant partition (@quorum@) for the operation to succeed. In a N shards with 1 replica scenario, there will need to be a single shard active (in this case, @one@ and @quorum@ is the same).

+p. The @refresh@ parameter can be set to @true@ in order to refresh the relevant shards after the bulk operation has occurred and make it searchable. Setting it to @true@ should be done after careful thought and verification that this does not cause a heavy load on the system (and slows down indexing).
