Perhaps you should try some spelling variations:
filosofia da » filosofia del, filosofia e, filosofia della
filosofia de » filosofia del
day studium » das studium, d studium, day studies
dem studium » das studium, im studium, zum studium

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: fast ((day studium) OR (dem studium)) d ((filosofia da) OR (filosofia de)) literatura.
• The words AND, OR and NOT may confuse the search; try adding quotes: "fast ((day studium) or (dem studium)) d ((filosofia da) OR (filosofia de)) literatura".
• Adding a wildcard symbol may retrieve word variants: fast ((day studium) or (dem studium)) d ((filosofia da) OR (filosofia de)) literatura*.
