Perhaps you should try some spelling variations:
20 martin » 10 martin, v2.0 martin, 20 marine
1823 1889 » 1820 1889, 1811 1889, 1888 1889
2 marine » 2 machine
21 1889 » 2 1889, 21 1879, 21 1809
1 1889 » _ 1889, 1 1819, 1 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%((20 martin) OR (2 marine)) %((((21 1889) OR (1 1889))) OR (((23 1889) OR (1823 1889))))-1976%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22heidegger%((20 martin) or (2 marine)) %((((21 1889) or (1 1889))) or (((23 1889) OR (1823 1889))))-1976%22".
• Adding a wildcard symbol may retrieve word variants: %22heidegger%((20 martin) or (2 marine)) %((((21 1889) or (1 1889))) or (((23 1889) OR (1823 1889))))-1976%22*.
