Perhaps you should try some spelling variations:
2 gustav » _ gustav, 8 gustav, dr gustav
f gustav » _ gustav, 8 gustav, dr gustav
2f 1878 » 28 1878, 29 1878, 2d 1878
18 1878 » 16 1878, 10 1878, 12 1878
1 1878 » 16 1878, _ 1878, 1 1808

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: %22stresemann%((2 gustav) OR (f gustav)) %((2f 1878) OR (((18 1878) OR (1 1878))))-1929%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22stresemann%((2 gustav) or (f gustav)) %((2f 1878) or (((18 1878) OR (1 1878))))-1929%22".
• Adding a wildcard symbol may retrieve word variants: %22stresemann%((2 gustav) or (f gustav)) %((2f 1878) or (((18 1878) OR (1 1878))))-1929%22*.
