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%((c martin) OR (((((2 martin) OR (12 martin))) OR (((12 marie) OR (12 marine)))))) %((21 1879) OR (1 1889))-1976%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22heidegger%((c martin) or (((((2 martin) OR (12 martin))) or (((12 marie) or (12 marine)))))) %((21 1879) or (1 1889))-1976%22".
• Adding a wildcard symbol may retrieve word variants: %22heidegger%((c martin) or (((((2 martin) OR (12 martin))) or (((12 marie) or (12 marine)))))) %((21 1879) or (1 1889))-1976%22*.
