replicas property

To add a replica index, you must provide the complete set of replicas to this parameter. If you omit a replica from this list, the replica turns into a regular, standalone index that will no longer by synced with the primary index. Modifier - virtual(\"REPLICA\"). Create a virtual replica, Virtual replicas don't increase the number of records and are optimized for Relevant sorting.
