Perhaps you should try some spelling variations:
die filosofica » di filosofia, de filosofia, e filosofica
neue studien » neue medien, neue stufe
filosofica e » filosofia e, filosofica da, filosofia de
e literature » e literatur, life literature, prose literature
die studien » die studie

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: tests ((neue studien) OR (die studien)) die filosofica e literature.
• Adding a wildcard symbol may retrieve word variants: tests ((neue studien) or (die studien)) die filosofica e literature*.
