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