Perhaps you should try some spelling variations:
2c martin » c martin, 27 martin, 29 martin
20 martin » 10 martin, v2.0 martin, 20 marine
1823 1889 » 1820 1889, 1811 1889, 23 1889
1888 1889 » 1888 1985, 1811 1889, 1820 1889
2 martin » 12 martin, 2 marine
2f 1889 » 23 1889, 2 1889, f 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 (20 martin))) OR (2 martin)) %((2f 1889) OR (((1823 1889) OR (1888 1889))))-1976%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22heidegger%((((2c martin) or (20 martin))) or (2 martin)) %((2f 1889) or (((1823 1889) OR (1888 1889))))-1976%22".
• Adding a wildcard symbol may retrieve word variants: %22heidegger%((((2c martin) or (20 martin))) or (2 martin)) %((2f 1889) or (((1823 1889) OR (1888 1889))))-1976%22*.
