Search across one or more distributed search peers
When performing a distributed search from a search head, you can restrict your searches to specific search peers (also known as "indexer nodes") by default and in your saved and scheduled searches. The names of your Splunk search peers are saved as values in the "splunk_server" field. For more information about distributed search, see "What is distributed search?" in the Distributed Deployment manual.
If no search peer is specified, your search accesses all search peers you have permission to access. The default peers that you can access are controlled by the roles and permissions associated with your profile and set by your Splunk admin. For more information, see "About users and roles" in the Admin manual.
The ability to restrict your searches to specific peers can be useful when there is high latency to certain search peers and you do not want to search them by default. When you specify one or more peers, those are the only servers that are included in the search.
You can specify different peers to search in the same way that you specify other field names and values. In this case, the field name is "splunk_server" and the field value is the name of a particular distributed peer:
Note: You can use the value "local" to refer to the Splunk instance that you are searching from; in other words, the search head itself.
Keep in mind that field names are case sensitive; Splunk will not recognize a field name if the case doesn't match.
Example 1: Return results from specified search peers.
error (splunk_server=NYsplunk OR splunk_server=CAsplunk) NOT splunk_server=TXsplunk
Example 2: Search different indexes on distributed search peers "foo" or "bar".
(splunk_server=foo index=main 404 ip=10.0.0.0/16) OR (splunk_server=bar index=mail user=admin)
Specify one or multiple indexes to search
