Issues with track search

[noabarlia]

I am facing some issues when searching tracks via the search bar. When seaching courses, everything works fine and I get the expected results. Since I am using the same component (in the front-end) in both cases, I guess that the problem is sourced somewhere in the back-end. Anyone else dealing with the same issue?

To Reproduce
Steps to reproduce the behavior:

1. Run the website: npm run serve
2. Authenticate.
3. Search any track name.

Expected behavior
The track should appear in the result.
