Perhaps you should try some spelling variations:
pela literatura » pena literatura, a literatura, de literatura
die filosofia » di filosofia, de filosofia, e filosofia
la literatura » la litterature, a literature
aue studien » neue studien, ante studien, lage studien
studien die » studie die, studien der
tests aue » tests auf, tests aus, tests acute

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: "tests aue studien die filosofia ((pela literatura) OR (la literatura))".
• Adding a wildcard symbol may retrieve word variants: tests aue studien die filosofia ((pela literatura) OR (la literatura))*.
