An index agent that is disabled cannot be started and is not started automatically when its associated Content Server is started. You can disable an index agent only after it has been stopped. To start a disabled index agent that is not running, you must enable the index agent first, using the instructions in Enabling index agents.
To disable an index agent:
Connect to the repository as user who has system administrator or superuser privileges.
Navigate to Administration > Indexing Management > Index Agents and Index Servers.
Select the correct index agent.
If the index agent is running, select Tools > Stop.
Select Tools > Disable.
Confirm that you want the index agent disabled.
The index agent’s status changes to disabled.
