Typesense doesn't support parentheses in field names

Gotcha. I guess I will try to update the Collection then, and/or dump + re-index + retry. Dumb idea anyway to not use sluggified values, I know.

If you need access control for individual records, you want to use a Scoped Search API key that is generated on the backend, pass it to the FE and make calls with that

Yeah, that data is behind a paywall mostly, so I will have to dig into that.
