One search head to search across two separate indexer clusters?

[varunmalhotra1]

I am running two setups of Splunk, one is in Datacenter and another is in AWS.

DC : 2 Node search heads, 3 nodes : indexers, 1 deployment server & license manager
AWS : 2 Node search heads, 3 nodes : indexers, 1 deployment server & license manager

I am trying to add AWS indexer cluster to DC search head. If this is possible we will stop the AWS hosted SHs because we want to keep only one SH cluster which should be able to search across two distinct indexer clusters.
Please note that there is no replication or any connection between the AWS hosted and DC hosted indexer cluster. We don't want to setup multisite indexer clustering.

Can this be done ?

You can add any number of search peers to a search head (non-clustered indexers), or add search heads to any number of cluster masters (clustered indexers).
Then a search will run over all indexers, giving you unified results.
