When we use the Search function in Learning our new Courses do not show up?

Summary:

We used to be able to Search any Course but now we need to click on Browse Catalogue instead to find the Courses. However an employee needs to be able to Search a Course Name and find the course. This used to work until recently. We still load the Courses up the same way so unsure why the Search is failing to get results even though the course has been loaded up in the backend.

Content (required):

For example if we look up the Search for 'TOM', the results give us the 2020 Tom course and the 2021 Tom course but not the 2022 Tom course that was loaded up a few weeks ago..
