Requirements This test assumes you have a working Moodle global search setup with Apache Solr or another search engine configured and enabled. Testing Create 4 courses A, B, C, and D. In each course add a label with the text 'Trexelvort A', 'Trexelvort B', etc. matching the course name. Set up guest access to be allowed in course B, and allowed with a password in course C (not allowed in A or D). In the permissions for course D, add an override so that the authenticated user role has moodle/course:view permission. Find or create two test accounts, referred to as U1 and U2. U1 should be enrolled as a student in course A. U2 should not be enrolled in any of these courses. Update the global search index (by waiting for cron, running the scheduled task manually, doing it from the commandline; whichever way is easiest), to ensure it has indexed the four new courses. Log in as user 1 and search for 'Trexelvort'. The result should only include Trexelvort A (where the user is enrolled). Log in as user 2 and do the search. There should be no results. As admin, go to the 'Manage global search' settings page and turn on the 'Searchable courses' option (set it to 'Search all courses user can access'). Log in as user 1 and search for 'Trexelvort'. The result should now include Trexelvort A, B, and D (where the user is enrolled plus the two places that are available straight off). Log in as user 2 and do the search. The result should include Trexelvort B and D. Still as user 2, visit course C and log in as guest, typing in the guest password. Repeat the search.  The result should now include Trexelvort B, C, and D. As admin, do the search. This should show all four results.
