• If you are trying to use Boolean operators, they must be ALL CAPS: %xgreat britain %((2f foreign) OR (24 foreign)) relations %((2f denmark) OR (2 denmark)) %((2f early) OR (2.1 early)) works to 1800%22*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%xgreat britain %((2f foreign) OR (24 foreign)) relations %((2f denmark) or (2 denmark)) %((2f early) or (2.1 early)) works to 1800%22*".
