Perhaps you should try some spelling variations:
der filosofia » de filosofia, e filosofia, di filosofia
e literatura » de literatura, y literatura, e literatur
filosofia e » filosofia de, filosofia del
die studio » die studie, die studia, die studien
de studio » de estudio, _ studio, a studio

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: "tests ((die studio) OR (de studio)) der filosofia e literatura".
• Adding a wildcard symbol may retrieve word variants: tests ((die studio) OR (de studio)) der filosofia e literatura*.
