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