Search function not working

Coming back to this one. it isn’t working still.

I created a simple search box. It is searching for users. There are 4 users in the data base currently, all who have signed up through the app. When I search for one of the users, nothing shows up as an option to select. As Gaby suggested, I looked and there were no constraints.

I find this super interesting, because search in any of our databases does not seem to be working. Here is another example where search is set up as work flow and not returning results.

Thank you!
