I don't know if at the present you can do such things without extra
programming,
but when I asked it long, long time ago (when I was starting with zope), the
answer
was to create a third index with the concatenated values of my keys.

In your case:
professor_name, course_number, and student_name. Of couse, you will
have to limit the size of those fields and add white spaces at the end.
