Perhaps you should try some spelling variations:
2c martin » c martin, 2 martin, 27 martin
12 martin » 2 martin, 12 marine, 12 main
1823 1889 » 1820 1889, 1811 1889, 1888 1889
2f 1889 » f 1889, 22 1889, 27 1889
24 1889 » 24 1819, 24 1879, 22 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)) %((((((2f 1889) OR (24 1889))) OR (2 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 (12 martin)) %((((((2f 1889) or (24 1889))) or (2 1889))) or (((23 1889) OR (1823 1889))))-1976%22".
• Adding a wildcard symbol may retrieve word variants: %22heidegger%((2c martin) or (12 martin)) %((((((2f 1889) or (24 1889))) or (2 1889))) or (((23 1889) OR (1823 1889))))-1976%22*.
