Before you begin
- Required permission: Workspace administrator
- Required license: Team or higher to save settings and to change providers and servers. On Free, you can only view the settings and run search tests.
- Search terms are sent to external providers. AI mode can use a question as the search term, so instruct users not to enter confidential content.

The page consists of the Basics, Search providers, Usage & security, and External MCP tabs. After you change a value, you must select Save for it to be applied.

- A single search can try multiple providers, so the daily limit differs from the provider's actual billing cap.
