• If you are trying to use Boolean operators, they must be ALL CAPS: %great britain %((((2f foreign) OR (22 foreign))) OR (4 foreign)) relations %2f denmark %((22 early) OR (1722 early)) works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%great britain %((((2f foreign) or (22 foreign))) or (4 foreign)) relations %2f denmark %((22 early) OR (1722 early)) works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %great britain %((((2f foreign) or (22 foreign))) or (4 foreign)) relations %2f denmark %((22 early) OR (1722 early)) works to 1800%22*.
