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))) OR (((12 martin) OR (12 main)))) %((((2f 1889) OR (23 1889))) OR (((((2 1889) OR (2 1829))) OR (_ 1889))))-1976%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22heidegger%((((2c martin) OR (2 martin))) or (((12 martin) or (12 main)))) %((((2f 1889) or (23 1889))) or (((((2 1889) or (2 1829))) or (_ 1889))))-1976%22".
• Adding a wildcard symbol may retrieve word variants: %22heidegger%((((2c martin) OR (2 martin))) or (((12 martin) or (12 main)))) %((((2f 1889) or (23 1889))) or (((((2 1889) or (2 1829))) or (_ 1889))))-1976%22*.
