Most SPL commands are processed on both the federated and remote search heads in standard mode searches, and require knowledge objects to be defined on both search heads. The following commands are processed only on the federated search head and don't require any relevant knowledge objects to be defined on the remote search head in order for searches to complete successfully:

• sendalert
• mcollect
• outputlookup

The sendemail command, which doesn't use knowledge objects, is also processed only on the federated search head in standard mode federated searches.

See Manage knowledge objects for standard mode federated providers for more information about using knowledge objects in standard mode federated searches.
