2f foreign » 2 foreign, 23 foreign, 22 foreign
24 foreign » 4 foreign, 2 foreign, 14 foreign
2f denmark » 22 denmark, 23 denmark, 2.3 denmark
13 denmark » 1 denmark, _ denmark, 5 denmark
1722 early » 1727 early
2 denmark » _ denmark, 5 denmark, 4 denmark

• If you are trying to use Boolean operators, they must be ALL CAPS: %great britain %((2f foreign) OR (24 foreign)) relations %((((2f denmark) OR (2 denmark))) OR (((13 denmark) OR (3 denmark)))) %1722 early works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%great britain %((2f foreign) or (24 foreign)) relations %((((2f denmark) or (2 denmark))) or (((13 denmark) OR (3 denmark)))) %1722 early works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %great britain %((2f foreign) or (24 foreign)) relations %((((2f denmark) or (2 denmark))) or (((13 denmark) OR (3 denmark)))) %1722 early works to 1800%22*.
