• The words AND, OR and NOT may confuse the search; try adding quotes: "(( langues key ideas transport costs la ) or ( guias ((der land) OR (der lange)) transfer 3 a ))~".
• Adding a wildcard symbol may retrieve word variants: (( langues key ideas transport costs la ) or ( guias ((der land) OR (der lange)) transfer 3 a ))*.
