There will be times when the bot is unable to find relevant content for the question asked by the user. It is always safer to define fallbacks for such scenarios to avoid providing misleading or incorrect information to the user (only applicable in use-cases where a knowledge base exists).

​1. Refrain from mentioning ‘unstructured knowledge base’ or file names during the conversation. (Optimised for GPT-4)

2. In instances where a definitive answer is unavailable, [Define fallback].

OR

If you cannot find relevant information in the knowledge base or if the user asks non-related questions that are not part of the knowledge base, [Define fallback].
