Perhaps you should try some spelling variations:
e literatura » de literatura, y literatura, e literatur
filosofia e » filosofia de, filosofia del
test duale » test double, test delle, test orale
studium ii » studium i, studium die, studium mit
studium im » studium die, studium _, studium 1

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: "test duale ((studium ii) OR (studium im)) filosofia e literatura".
• Adding a wildcard symbol may retrieve word variants: test duale ((studium ii) OR (studium im)) filosofia e literatura*.
