Perhaps you should try some spelling variations:
2c martin » 2 martin, 27 martin, 20 martin
29 martin » 29 martii, 9 martin, 29 marine
12 martin » 2 martin, 12 marine, 12 main
23 1889 » 1823 1889
2 1889 » 2 1829, _ 1889, 2 1819

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 (29 martin))) OR (c martin))) OR (12 martin)) %((23 1889) OR (2 1889))-1976%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22heidegger%((((((2c martin) OR (29 martin))) or (c martin))) or (12 martin)) %((23 1889) or (2 1889))-1976%22".
• Adding a wildcard symbol may retrieve word variants: %22heidegger%((((((2c martin) OR (29 martin))) or (c martin))) or (12 martin)) %((23 1889) or (2 1889))-1976%22*.
