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