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