• If you are trying to use Boolean operators, they must be ALL CAPS: %22great britain %((2f foreign) OR (2 foreign)) relations %2 denmark %((((2f early) OR (22 early))) OR (21 early)) works to 1800%22*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22great britain %((2f foreign) or (2 foreign)) relations %2 denmark %((((2f early) OR (22 early))) or (21 early)) works to 1800%22*".
