I am attempting to implement full-text search in a chat-like app that allows a user to search messages sent and received using Firebase on the backend. Initially I implemented Algolia for this purpose, but ran into some issues with the implementation because my index returned results with other users' messages and I couldn't immediately figure out how to filter without a proper user ref field (Algolia converts user ref fields to json for some reason).
So I decided to try Simple Search against the Firebase collection, but now I'm not getting any results (no errors, just no results).
How is full-text search like this typically accomplished in Flutterflow + Firebase?
