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