• If you are trying to use Boolean operators, they must be ALL CAPS: convention on biological diversity / (1992 ((june 5) OR (june 15))) / (2010 ((october 29) OR (((october 25) OR (october 23))))) / protocols, etc.
• The words AND, OR and NOT may confuse the search; try adding quotes: "convention on biological diversity / (1992 ((june 5) OR (june 15))) / (2010 ((october 29) or (((october 25) or (october 23))))) / protocols, etc".
• Adding a wildcard symbol may retrieve word variants: convention on biological diversity / (1992 ((june 5) OR (june 15))) / (2010 ((october 29) or (((october 25) or (october 23))))) / protocols, etc*.
