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