Perhaps you should try some spelling variations:
a literatura » la literatura, a literature, y literatura
filosofia a » filosofia da, filosofia la, filosofia e
studium im » studium die, studium _, studium 1
studium i » studium _, studium 1, studium 3
test das » test des, test day, west das

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: test das ((((studium i) OR (studium im))i) OR (((studium i) OR (studium im)))) filosofia a literatura*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "test das ((((studium i) OR (studium im))i) or (((studium i) OR (studium im)))) filosofia a literatura*".
