Perhaps you should try some spelling variations:
de litterature » la litterature, et litterature
die filosofia » di filosofia, de filosofia, e filosofia
de literatura » la literatura, y literatura, a literatura
studium die » studium der, studium des
westen das » testen das, westen der, westfalen das
west das » west ak, west a, west d.d

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