Perhaps you should try some spelling variations:
del litterature » de litterature, des litteratures, et litterature
durante studien » ante studien, duale studien, dokumente studien
dante studies » dance studies, date studies, mantle studies
die filosofia » di filosofia, de filosofia, e filosofia

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: "texto ((durante studien) OR (dante studies)) die filosofia del litterature".
• Adding a wildcard symbol may retrieve word variants: texto ((durante studien) OR (dante studies)) die filosofia del litterature*.
