Perhaps you should try some spelling variations:
da literatura » la literatura, a literatura, na literatura
de literatura » de litterature, la literatura, y literatura
a filosofia » la filosofia, e filosofia, di filosofia
studium a » studium am, studium ad, studium _
bist das » ist das, list das, geist 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: "bist das studium a filosofia ((da literatura) OR (de literatura))".
• Adding a wildcard symbol may retrieve word variants: bist das studium a filosofia ((da literatura) OR (de literatura))*.
