• If you are trying to use Boolean operators, they must be ALL CAPS: %22heidegger%((((2c martin) OR (((20 martin) OR (10 martin))))) OR (((12 martin) OR (2 martin)))) %((((23 1889) OR (1823 1889))) OR (_ 1889))-1976%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22heidegger%((((2c martin) or (((20 martin) OR (10 martin))))) or (((12 martin) or (2 martin)))) %((((23 1889) or (1823 1889))) or (_ 1889))-1976%22".
• Adding a wildcard symbol may retrieve word variants: %22heidegger%((((2c martin) or (((20 martin) OR (10 martin))))) or (((12 martin) or (2 martin)))) %((((23 1889) or (1823 1889))) or (_ 1889))-1976%22*.
