Hello everybody,
We have a Power Portal project and we have a Portal Search for a custom table. A week ago this search function worked as expected and we never had any problem with it. But since a few days ago we never get any results back, no matter the input. As far as we can remember we haven't made any particular changes related to the search functionality.
Before:

Now:

So I've done some checks to see what causes the problem, but unfortunately I haven't found anything odd.
The checks I've made:
1. Checked if site settings were correct:

2. Checked for a Portal Search view:

3. Checked entity permissions:

4. Checked Site Marker:

5. We have done an update in the portal, rebuilt the index and restarted the portal.
Yet these checks didn't result in a succes.
We hope someone could help us out!
Thanks for the help.
