Perhaps you should try some spelling variations:
2f emperor » _ emperor, i emperor, vi emperor
ii emperor » i emperor, _ emperor
24 1769 » 24 1765, 24 1768, 24 1779
24 1789 » 4 1789, 14 1789, 24 1783
25 i » 25 a, 5 i, 25 1
25 _ » 2 _, 20 _, 22 _
21 _ » 2 _, 20 _

• If you are trying to use Boolean operators, they must be ALL CAPS: %22napoleon %((((25 i) OR (((25 _) OR (21 _))))) OR (2 i)) %((2f emperor) OR (ii emperor)) of the french %((24 1769) OR (24 1789))-1821%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22napoleon %((((25 i) or (((25 _) OR (21 _))))) or (2 i)) %((2f emperor) or (ii emperor)) of the french %((24 1769) or (24 1789))-1821%22".
• Adding a wildcard symbol may retrieve word variants: %22napoleon %((((25 i) or (((25 _) OR (21 _))))) or (2 i)) %((2f emperor) or (ii emperor)) of the french %((24 1769) or (24 1789))-1821%22*.
