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