• If you are trying to use Boolean operators, they must be ALL CAPS: %zgreat britain %2f foreign relations %((((2f denmark) OR (((2.3 denmark) OR (2.4 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 %2f foreign relations %((((2f denmark) or (((2.3 denmark) OR (2.4 denmark))))) or (23 denmark)) %2f early works to 1800%22*".
