Hi @realsplunk,
If you want to use standalone searchhead to search data from all clustered indexers without duplicate data then point your standalone search head to cluster master of Indexer cluster, do not add any indexer in Distributed search -> Search Peer.
When you will point standalone search head to cluster master of all indexer, Distibuted search -> Search Peer will be automatically updated with all indexers. Now when you search from this stand alone search head it will not display duplicate events from clustered indexers.
Thanks,
Harshil
