22great britain » great britain, xgreat britain, great brittain
zgreat britain » great britain, xgreat britain, great brittain

13 denmark » 3 denmark, 1 denmark, _ denmark
2f early » 21 early, ef early, f early

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: %((22great britain) OR (zgreat britain)) %2f foreign relations %((22 denmark) OR (((23 denmark) OR (13 denmark)))) %((2f early) OR (20 early)) works to 1800%22*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((22great britain) or (zgreat britain)) %2f foreign relations %((22 denmark) or (((23 denmark) OR (13 denmark)))) %((2f early) or (20 early)) works to 1800%22*".
