Perhaps you should try some spelling variations:
duale studium » duales studium, dualen studium, das studium
safe studium » safe studio, ganze studium, jahre studium
ii filosofia » di filosofia, la filosofia, e filosofia
e literature » e literatur, life literature, prose literature
filosofia e » filosofia de, filosofia del

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 (duale studium)) ii filosofia e literature".
• Adding a wildcard symbol may retrieve word variants: tests ((safe studium) OR (duale studium)) ii filosofia e literature*.
