Perhaps you should try some spelling variations:
2c martin » 2 martin, 20 martin, 22 martin
21 martin » 1 martin, 11 martin, 21 martii
12 martin » 2 martin, 12 marine, 12 main
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 (21 martin))) OR (c martin))) OR (12 martin)) %((2f 1889) OR (23 1889))-1976%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22heidegger%((((((2c martin) OR (21 martin))) or (c martin))) or (12 martin)) %((2f 1889) or (23 1889))-1976%22".
• Adding a wildcard symbol may retrieve word variants: %22heidegger%((((((2c martin) OR (21 martin))) or (c martin))) or (12 martin)) %((2f 1889) or (23 1889))-1976%22*.
