• If you are trying to use Boolean operators, they must be ALL CAPS: %((zgreat britain) OR (great britain)) %((2f foreign) OR (2 foreign)) relations %((((2f denmark) OR (22 denmark))) OR (23 denmark)) %2f early works to 1800%22*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((zgreat britain) OR (great britain)) %((2f foreign) or (2 foreign)) relations %((((2f denmark) or (22 denmark))) or (23 denmark)) %2f early works to 1800%22*".
