Perhaps you should try some spelling variations:
2c martin » c martin, 27 martin, 29 martin
1823 1889 » 1820 1889, 1811 1889, 1888 1889
2 martin » 12 martin, 2 marine
226 1889 » 22 1889, 236 1889, 2 1889
2f 1889 » 2 1889, f 1889, 22 1889

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: %22heidegger%((2c martin) OR (2 martin)) %((((((2f 1889) OR (23 1889))) OR (226 1889))) OR (1823 1889))-1976%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22heidegger%((2c martin) or (2 martin)) %((((((2f 1889) OR (23 1889))) or (226 1889))) or (1823 1889))-1976%22".
• Adding a wildcard symbol may retrieve word variants: %22heidegger%((2c martin) or (2 martin)) %((((((2f 1889) OR (23 1889))) or (226 1889))) or (1823 1889))-1976%22*.
