Perhaps you should try some spelling variations:
2c martin » c martin, 27 martin, 29 martin
2 martin » 12 martin, 2 marine
22 1889 » 226 1889, 23 1889, 12 1889
22 1888 » 22 1838, 1822 1888
2 1889 » 23 1889, 2 1829, _ 1889

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)) %((((22 1889) OR (22 1888))) OR (2 1889))-1976%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22heidegger%((2c martin) or (2 martin)) %((((22 1889) OR (22 1888))) or (2 1889))-1976%22".
• Adding a wildcard symbol may retrieve word variants: %22heidegger%((2c martin) or (2 martin)) %((((22 1889) OR (22 1888))) or (2 1889))-1976%22*.
