Perhaps you should try some spelling variations:
der filosofica » de filosofia, e filosofia, di filosofia
e filosofica » e filosofia, e filosofiche, a filosofia
e literatura » de literatura, y literatura, e literatur
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 studium ((der filosofica) OR (e filosofica)) e literatura".
• Adding a wildcard symbol may retrieve word variants: bist das studium ((der filosofica) OR (e filosofica)) e literatura*.
