Perhaps you should try some spelling variations:
2 gustav » _ gustav, 8 gustav, f gustav
2f 1878 » 29 1878, 2d 1878
28 1878 » 28 1873, 28 1808, 28 1848
18 1878 » 1 1878, 16 1878, 10 1878
28 1874 » 28 1824, 28 1873

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: %22stresemann%2 gustav %((2f 1878) OR (((((28 1878) OR (18 1878))) OR (28 1874))))-1929%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22stresemann%2 gustav %((2f 1878) or (((((28 1878) OR (18 1878))) or (28 1874))))-1929%22".
• Adding a wildcard symbol may retrieve word variants: %22stresemann%2 gustav %((2f 1878) or (((((28 1878) OR (18 1878))) or (28 1874))))-1929%22*.
