Perhaps you should try some spelling variations:
la litterature » a literature
die filosofia » di filosofia, de filosofia, e filosofia
filosofia la » filosofia da, filosofia le, filosofica da
studies die » studie die, studien die, studies does
text case » text class, text csv, context case
text code » text copy, text co

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: "((text case) OR (text code)) studies die filosofia la litterature".
• Adding a wildcard symbol may retrieve word variants: ((text case) OR (text code)) studies die filosofia la litterature*.
