• If you are trying to use Boolean operators, they must be ALL CAPS: %22heidegger%((((((2c martin) OR (22 martin))) OR (((21 martin) OR (21 martii))))) OR (2 martin)) %((2f 1889) OR (2 1889))-1976%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22heidegger%((((((2c martin) OR (22 martin))) or (((21 martin) or (21 martii))))) or (2 martin)) %((2f 1889) or (2 1889))-1976%22".
• Adding a wildcard symbol may retrieve word variants: %22heidegger%((((((2c martin) OR (22 martin))) or (((21 martin) or (21 martii))))) or (2 martin)) %((2f 1889) or (2 1889))-1976%22*.
