Copilot studio doesn't have direct fuzzy logic setting but having trigger phrases as comprehensive can cover wide range of inputs.

I need to trigger a topic in Copilot Studio with functionality similar to smart matching capabilities in Entities, where the system can recognize and match input without requiring me to list all the possible phrases that users might input. This would greatly improve flexibility and efficiency. Let me know the best approach to achieve this.

Hi nimalj ,

The Solution for your problem could be using Inputs in Topics. The Description that you provide in LLM itself is capable to extract and identify the required pattern.

You can read through the below post that i have written.
