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