Perhaps you should try some spelling variations:
2.2 martin » 2012 martin, 2.2 main, 12 martin
22 martin » 12 martin, 22 martii, 42 martin
2 martin » 12 martin, 2 marine
2f 1889 » 2 1889, f 1889, 22 1889
23 1889 » 1823 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%((((((22 martin) OR (2.2 martin))) OR (c martin))) OR (2 martin)) %((2f 1889) OR (23 1889))-1976%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22heidegger%((((((22 martin) OR (2.2 martin))) or (c martin))) or (2 martin)) %((2f 1889) or (23 1889))-1976%22".
• Adding a wildcard symbol may retrieve word variants: %22heidegger%((((((22 martin) OR (2.2 martin))) or (c martin))) or (2 martin)) %((2f 1889) or (23 1889))-1976%22*.
