You can search for a specific course, or a group of courses
such as BIOB (but substring matching must be on).
Do not add the course term, eg enter ASTB03 not ASTB03S
You can also search via subject name for any entry in the full index.
(Match Substrings means that search terms can be part of larger
words, eg bio will match "Biology" as well as
"BIOB03". Match Words restricts the search to match
full words, thus bio would probably not match anything.)
