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