Perhaps you should try some spelling variations:
de litterature » la litterature, et litterature
duales studium » das studium
de literatura » la literatura, y literatura, a literatura
tests duales » tests dalekjs, tests des, neues duales
ii filosofia » di filosofia, la filosofia, e filosofia
studium ii » studium im, studium i, studium die

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 duales studium ii filosofia ((de literatura) OR (de litterature))*".
