Perhaps you should try some spelling variations:
ganze studium » ganzen studien, ohne studium, jahre studium
safe studium » safe studio, duale studium, jahre studium
im filosofia » em filosofia, la filosofia, e filosofia
filosofia e » filosofia de, filosofia del
literatur » literature

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 ((safe studium) OR (ganze studium)) im filosofia e literatur".
• Adding a wildcard symbol may retrieve word variants: tests ((safe studium) OR (ganze studium)) im filosofia e literatur*.
