Perhaps you should try some spelling variations:
2c martin » c martin, 20 martin, 21 martin
12 martin » 12 marine, 12 main, 12 marie
2 martin » 2 marine
23 1889 » 1823 1889
2 1889 » 2 1829, 2 1819, 2 1809
_ 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 (2 martin))) OR (12 martin)) %((23 1889) OR (((2 1889) OR (_ 1889))))-1976%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22heidegger%((((2c martin) OR (2 martin))) or (12 martin)) %((23 1889) or (((2 1889) or (_ 1889))))-1976%22".
• Adding a wildcard symbol may retrieve word variants: %22heidegger%((((2c martin) OR (2 martin))) or (12 martin)) %((23 1889) or (((2 1889) or (_ 1889))))-1976%22*.
