Perhaps you should try some spelling variations:
der filosofica » e filosofica, e filosofia, di filosofia
de filosofia » e filosofia, di filosofia, la filosofia
e literatura » de literatura, y literatura, e literatur
das studio » sas studio, das studium, das stadion
bist das » ist das, list das, geist das

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "bist das studio ((der filosofica) OR (de filosofia)) e literatura".
• Adding a wildcard symbol may retrieve word variants: bist das studio ((der filosofica) OR (de filosofia)) e literatura*.
