Perhaps you should try some spelling variations:
2c martin » c martin, 27 martin, 29 martin
12 martin » 12 marine, 12 main, 12 marie
2 martin » 2 marine
f 1889 » 1 1889
_ 1889 » _ 1880, _ 1819, _ 1849
2 1889 » 23 1889, 2 1829, 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)))) %((((2((f 1889) OR (_ 1889))) OR (((f 1889) OR (_ 1889))))) OR (2 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)))) %((((2((f 1889) OR (_ 1889))) or (((f 1889) OR (_ 1889))))) or (2 1889))-1976%22".
• Adding a wildcard symbol may retrieve word variants: %22heidegger%((2c martin) or (((12 martin) or (2 martin)))) %((((2((f 1889) OR (_ 1889))) or (((f 1889) OR (_ 1889))))) or (2 1889))-1976%22*.
