Perhaps you should try some spelling variations:
2c martin » 2 martin, 20 martin, 21 martin
12 martin » 2 martin, 12 marine, 12 marie
12 main » 12 mai, 12 making, 12 marine
23 1889 » 1823 1889
2 1829 » _ 1829
2 1809 » 2 1808, 2 1800, 2 1819
_ 1889 » _ 1880, _ 1819, _ 1849

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 (((12 martin) OR (12 main)))) %((23 1889) OR (((((2 1829) OR (2 1809))) OR (_ 1889))))-1976%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22heidegger%((((2c martin) OR (c martin))) or (((12 martin) or (12 main)))) %((23 1889) or (((((2 1829) or (2 1809))) or (_ 1889))))-1976%22".
• Adding a wildcard symbol may retrieve word variants: %22heidegger%((((2c martin) OR (c martin))) or (((12 martin) or (12 main)))) %((23 1889) or (((((2 1829) or (2 1809))) or (_ 1889))))-1976%22*.
