Perhaps you should try some spelling variations:
del literatura » de literatura, pela literatura, e literatura
das filosofia » da filosofia, la filosofia, di filosofia
da literatura » la literatura, a literatura, de literatura
studium das » studium des, studium der, studium die

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: ((suite _) OR (quite _)) studium das filosofia ((del literatura) OR (da literatura)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((suite _) or (quite _)) studium das filosofia ((del literatura) OR (da literatura))".
• Adding a wildcard symbol may retrieve word variants: ((suite _) or (quite _)) studium das filosofia ((del literatura) OR (da literatura))*.
