• If you are trying to use Boolean operators, they must be ALL CAPS: %22heidegger%((c martin) OR (((2 martin) OR (((12 martin) OR (12 marine)))))) %((2f 1889) OR (f 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 marine)))))) %((2f 1889) or (f 1889))-1976%22".
