Perhaps you should try some spelling variations:
e literatura » de literatura, y literatura, e literatur
filosofia e » filosofia de, filosofia del
studium ii » studium im, studium die, studium mit
studium i » studium im, studium _, studium 1
test das » test des, test day, west 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: "test das ((studium ii) OR (studium i)) filosofia e literatura*".
