Perhaps you should try some spelling variations:
"spanish universities" » "japanese universities", "class universities", "chinese universities"
"spanish university" » "japanese university", "monash university", "turkish university"
"smith university" » "city university", "within 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: (("smith university") OR ((("spanish university") OR ("spanish universities")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"smith university\") or (((\"spanish university\") OR (\"spanish universities\"))))".
• Removing quotes may allow a broader search: (( smith university ) or ((( spanish university ) OR ( spanish universities )))).
• Adding a wildcard symbol may retrieve word variants: (("smith university") or ((("spanish university") OR ("spanish universities"))))*.
