[R04] Course Browsing and Search: Enable users to search for courses by name, code, tags, and academic level. (i have question what code we need to put here ? is the code of Professor that make that cours or something?)
The code of a course is like an ID for the course. For example, "ING3-DM" can be a code, or "CS301", etc. It is up to you to enforce a way. Usually, the admin person gives codes to courses.
