Perhaps you should try some spelling variations:
et litterature » la litterature, art literature
e litterature » de litterature, en litterature, e literature
di filosofia » la filosofia, e filosofia
studium di » studium die, studium i, studium ii
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 di filosofia ((e litterature) OR (et litterature))*".
