Perhaps you should try some spelling variations:
12 machine » 2 machine, 11 machine, 13 machine
2c martin » c martin, 27 martin, 29 martin
1823 1889 » 1820 1889, 1811 1889, 1888 1889
2 martin » 12 martin, 2 marine
2f 1889 » 2 1889, f 1889, 24 1889
22 1889 » 226 1889, 2 1889, 22 1888

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 (((12 machine) OR (2 martin)))) %((((2f 1889) OR (22 1889))) OR (((23 1889) OR (1823 1889))))-1976%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22heidegger%((2c martin) or (((12 machine) or (2 martin)))) %((((2f 1889) OR (22 1889))) or (((23 1889) or (1823 1889))))-1976%22".
• Adding a wildcard symbol may retrieve word variants: %22heidegger%((2c martin) or (((12 machine) or (2 martin)))) %((((2f 1889) OR (22 1889))) or (((23 1889) or (1823 1889))))-1976%22*.
