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