• If you are trying to use Boolean operators, they must be ALL CAPS: %great britain %((((2f foreign) OR (23 foreign))) OR (4 foreign)) relations %((2f denmark) OR (2 denmark)) %22 early works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%great britain %((((2f foreign) or (23 foreign))) or (4 foreign)) relations %((2f denmark) OR (2 denmark)) %22 early works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %great britain %((((2f foreign) or (23 foreign))) or (4 foreign)) relations %((2f denmark) OR (2 denmark)) %22 early works to 1800%22*.
