• If you are trying to use Boolean operators, they must be ALL CAPS: (( 1 agenda i a literature oral ) OR ( _ ((agenda ii) OR (agenda iv)) _ literature arab )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( 1 agenda i a literature oral ) or ( _ ((agenda ii) OR (agenda iv)) _ literature arab ))".
• Adding a wildcard symbol may retrieve word variants: (( 1 agenda i a literature oral ) or ( _ ((agenda ii) OR (agenda iv)) _ literature arab ))*.
