• The words AND, OR and NOT may confuse the search; try adding quotes: "(( langue et idea transport costs land ) or ( bias der lander ((transfer 3) OR (transfer _)) a ))~".
• Adding a wildcard symbol may retrieve word variants: (( langue et idea transport costs land ) or ( bias der lander ((transfer 3) OR (transfer _)) a ))*.
