Using the Cluster tab in the Admin page, you can configure the cluster setup.
You have to specify whether the setup is a single node or multinode.
The default is a single node which represents stand-alone instance.
If you want to set up a cluster of multiple nodes then select the multinode option. Go to Menu -> Admin -> Cluster for each server in the cluster, as shown.
[Configure the cluster setup](doc: replication) with 1 index and 2 search servers which is our recommended configuration for a basic cluster.
Cluster Search setup requires SearchBlox license applied on all servers
