Perhaps you should try some spelling variations:
2c martin » c martin, 27 martin, 29 martin
2 machine » 8 machine
2 martin » 12 martin, 2 marine
23 1889 » 1823 1889
2 1889 » _ 1889, 2 1819, 2 1809
2 1829 » _ 1829

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