Perhaps you should try some spelling variations:
12 martin » 12 marine, 12 mating, 12 marketing
2 martin » 2 marine
12 marie » 12 marine, 12 market, 12 mai
12 main » 12 mai, 12 making, 12 marine
2f 1889 » 23 1889, 2 1889, f 1889
2 1819 » _ 1819, 2 1829, 2 1810
_ 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%((2 martin) OR (((((12 martin) OR (12 marie))) OR (12 main)))) %((2f 1889) OR (((2 1819) OR (_ 1889))))-1976%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22heidegger%((2 martin) or (((((12 martin) OR (12 marie))) or (12 main)))) %((2f 1889) or (((2 1819) or (_ 1889))))-1976%22".
• Adding a wildcard symbol may retrieve word variants: %22heidegger%((2 martin) or (((((12 martin) OR (12 marie))) or (12 main)))) %((2f 1889) or (((2 1819) or (_ 1889))))-1976%22*.
