• If you are trying to use Boolean operators, they must be ALL CAPS: %((((middle east's) OR (middle earth))) OR (((middle last) OR (middle class)))) %((2f foreign) OR (2 foreign)) relations %((20 united) OR (21 united)) states%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((((middle east's) OR (middle earth))) or (((middle last) or (middle class)))) %((2f foreign) or (2 foreign)) relations %((20 united) or (21 united)) states%22".
• Adding a wildcard symbol may retrieve word variants: %((((middle east's) OR (middle earth))) or (((middle last) or (middle class)))) %((2f foreign) or (2 foreign)) relations %((20 united) or (21 united)) states%22*.
