• The words AND, OR and NOT may confuse the search; try adding quotes: "%((middle east1) or (middle last)) %((2f foreign) or (3 foreign)) relations %((22 united) or (((21 united) OR (11 united)))) states%22".
• Adding a wildcard symbol may retrieve word variants: %((middle east1) or (middle last)) %((2f foreign) or (3 foreign)) relations %((22 united) or (((21 united) OR (11 united)))) states%22*.
