• The words AND, OR and NOT may confuse the search; try adding quotes: "%((middle east1) or (middle last)) %((2f foreign) OR (23 foreign)) relations %((((2f united) or (2 united))) or (21 united)) states%22".
• Adding a wildcard symbol may retrieve word variants: %((middle east1) or (middle last)) %((2f foreign) OR (23 foreign)) relations %((((2f united) or (2 united))) or (21 united)) states%22*.
