Perhaps you should try some spelling variations:
da literatura » la literatura, de literatura, na literatura
a literatura » la literatura, a literature, y literatura
die studium » dein studium, das studium, im studium
e filosofia » la filosofia
tests die » test die, tests der
studium e » studium _, studium 1, studium 3

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 die studium e filosofia ((da literatura) OR (a literatura))*".
