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
2f 1889 » f 1889, 22 1889, 24 1889
23 1889 » 1823 1889
2 1889 » 2 1829, _ 1889, 2 1819

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 (((12 martin) OR (2 martin)))) %((2f 1889) OR (((2 1889) OR (23 1889))))-1976%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22heidegger%((2c martin) or (((12 martin) or (2 martin)))) %((2f 1889) or (((2 1889) OR (23 1889))))-1976%22".
• Adding a wildcard symbol may retrieve word variants: %22heidegger%((2c martin) or (((12 martin) or (2 martin)))) %((2f 1889) or (((2 1889) OR (23 1889))))-1976%22*.
