Perhaps you should try some spelling variations:
2c martin » 27 martin, 29 martin, 20 martin
12 martin » 12 marine, 12 main, 12 marie
1823 1889 » 1820 1889, 1811 1889, 1888 1889
2 martin » 2 marine
2f 1889 » 2 1889, f 1889, 22 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 (c martin))) OR (((2 martin) OR (12 martin)))) %((((2f 1889) OR (23 1889))) OR (1823 1889))-1976%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22heidegger%((((2c martin) or (c martin))) or (((2 martin) OR (12 martin)))) %((((2f 1889) or (23 1889))) or (1823 1889))-1976%22".
• Adding a wildcard symbol may retrieve word variants: %22heidegger%((((2c martin) or (c martin))) or (((2 martin) OR (12 martin)))) %((((2f 1889) or (23 1889))) or (1823 1889))-1976%22*.
