• The words AND, OR and NOT may confuse the search; try adding quotes: "%((((middle ears) or (((middle eastern) OR (middle east))))) or (middle last)) %2f foreign relations %((2f united) or (((2 united) or (2 unity)))) states%22".
• Adding a wildcard symbol may retrieve word variants: %((((middle ears) or (((middle eastern) OR (middle east))))) or (middle last)) %2f foreign relations %((2f united) or (((2 united) or (2 unity)))) states%22*.
