+The infrastructure for deploying connectors can be managed by Elastic or self-managed. Managed connectors require an {enterprise-search-ref}/server.html[Enterprise Search] server connected to the Elastic Stack. Self-managed connectors are run on your own infrastructure and don't require the Enterprise Search service.
 
 By default, the AI Assistant queries all search connector indices. To override this behavior and customize which indices are queried, adjust the *Search connector index pattern* setting on the <<obs-ai-settings>> page. This allows precise control over which data sources are included in AI Assistant knowledge base.
