I have added 3 KBs i.e. website, doc and websearch. How to make website as primary KB? For now my bot is taking Doc as primary, but ideally it should use website or at least, it should merge both website & Doc information and respond.

You can always mention to it on the Kb description that it should favor results from one kb to others but you can't really set it that way anywhere like Michele says

Thanks to both of you for your kind reply.
