• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elgar retinal conference\") OR (\"elgar regional conferences\"))) or (\"((elgar retrieval) or (delay retrieval)) references\"))".
• Removing quotes may allow a broader search: (((( elgar retinal conference ) OR ( elgar regional conferences ))) or ( ((elgar retrieval) or (delay retrieval)) references )).
• Adding a wildcard symbol may retrieve word variants: (((("elgar retinal conference") OR ("elgar regional conferences"))) or ("((elgar retrieval) or (delay retrieval)) references"))*.
