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

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