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