• If you are trying to use Boolean operators, they must be ALL CAPS: %((zgreat britain) OR (xgreat britain)) %2 foreign relations %((2 denmark) OR (23 denmark)) %((2f early) OR (21 early)) works to 1800%22*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((zgreat britain) OR (xgreat britain)) %2 foreign relations %((2 denmark) or (23 denmark)) %((2f early) or (21 early)) works to 1800%22*".
