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