• If you are trying to use Boolean operators, they must be ALL CAPS: %((middle east1) OR (middle last)) %((2f foreign) OR (((3 foreign) OR (4 foreign)))) relations %((2f united) OR (((2((1 united) OR (1 units))) OR (((1 united) OR (1 units)))))) states%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((middle east1) or (middle last)) %((2f foreign) or (((3 foreign) or (4 foreign)))) relations %((2f united) or (((2((1 united) OR (1 units))) or (((1 united) OR (1 units)))))) states%22".
• Adding a wildcard symbol may retrieve word variants: %((middle east1) or (middle last)) %((2f foreign) or (((3 foreign) or (4 foreign)))) relations %((2f united) or (((2((1 united) OR (1 units))) or (((1 united) OR (1 units)))))) states%22*.
