Perhaps you should try some spelling variations:
"asean university" » "asian university", "aston university", "kean university"
"lean university" » "kean university", "mclean university", "henan university"
"aden university" » "allen university", "open university", "caen university"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("lean university") OR ((("asean university") OR ("aden university")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"lean university\") or (((\"asean university\") OR (\"aden university\"))))".
• Removing quotes may allow a broader search: (( lean university ) or ((( asean university ) OR ( aden university )))).
• Adding a wildcard symbol may retrieve word variants: (("lean university") or ((("asean university") OR ("aden university"))))*.
