Perhaps you should try some spelling variations:
2c martin » c martin, 20 martin, 21 martin
2 martin » 12 martin
2 marine » 2 machine
2f 1889 » 2 1889, f 1889, 22 1889
23 1889 » 1823 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 (((1((2 martin) OR (2 marine))) OR (((2 martin) OR (2 marine)))))) %((2f 1889) OR (23 1889))-1976%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22heidegger%((2c martin) or (((1((2 martin) OR (2 marine))) or (((2 martin) OR (2 marine)))))) %((2f 1889) or (23 1889))-1976%22".
• Adding a wildcard symbol may retrieve word variants: %22heidegger%((2c martin) or (((1((2 martin) OR (2 marine))) or (((2 martin) OR (2 marine)))))) %((2f 1889) or (23 1889))-1976%22*.
