Search under backstage not working

[bnore]

Describe the bug
Normal search doesn't work

To Reproduce
The search engine in the backstage is not working, to search a lab you need to:

1. Add Name of the lab
2. Filter
   This system will tell you that there are no labs under this name, so the right way is to:
3. Add Name of the lab
4. Select an option between (Is referee, with discourse ID, without discourse ID, with discourse sync errors) normally the one that works is with discourse ID
5. Search
   This will give you a list of all the labs with this name

Steps to reproduce the behavior:

1. Go to 'Name'
2. Click on 'Filter'
3. Scroll down to 'see all labs under that name'

Expected behavior
All labs under this name should appear, the problem with this is that they are not appearing on the backstage but are on the frontend

Screenshots
normal search on backstage:

on frontend:

with discourse ID added:

This is also affecting the number of labs that we can see on the backstage which differs on the number of labs that the public can see.
