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