How do i know use_cache is working?

We don't add anything to the response to indicate a cached response, since we didn't want to leak that detail.

Thank you, probably a debug mode or env would be helpful. Since we don't really use the search on the frontend

What type of debugging you would like to do here? Want to understand the use case better. Are you just wanting to confirm that the result is really a cached response?

I guess you're right, I don't really have a great/important use case so NVM that. I could just confirm the cache by updating the value.

Yes, that's the easiest way to test 🙂
