Perhaps you should try some spelling variations:
i emperor » _ emperor
24 1779 » 24 1789, 26 1779
24 1777 » 21 1777, 20 1777, 24 1797
24 1765 » 24 1795
2 1769 » 12 1769, 24 1769, 27 1769
25 _ » 2 _, 20 _, 21 _

Try widening your search to All Fields.

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: %22napoleon %((25 _) OR (2 i)) %i emperor of the french %((2 1769) OR (((((24 1779) OR (24 1777))) OR (((24 1768) OR (24 1765))))))-1821%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22napoleon %((25 _) or (2 i)) %i emperor of the french %((2 1769) or (((((24 1779) OR (24 1777))) or (((24 1768) or (24 1765))))))-1821%22".
• Adding a wildcard symbol may retrieve word variants: %22napoleon %((25 _) or (2 i)) %i emperor of the french %((2 1769) or (((((24 1779) OR (24 1777))) or (((24 1768) or (24 1765))))))-1821%22*.
