Perhaps you should try some spelling variations:
data studium » das studium, data studies, data studied
data studio » data studies, data study
filosofia y » filosofia _, filosofia de, filosofia da
filosofia e » filosofia de, filosofia del

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: list ((data studium) OR (data studio)) e ((filosofia y) OR (filosofia e)) literatura.
• The words AND, OR and NOT may confuse the search; try adding quotes: "list ((data studium) OR (data studio)) e ((filosofia y) or (filosofia e)) literatura".
• Adding a wildcard symbol may retrieve word variants: list ((data studium) OR (data studio)) e ((filosofia y) or (filosofia e)) literatura*.
