Perhaps you should try some spelling variations:
filosofia y » filosofia _, filosofia de, filosofia da
filosofia e » filosofia de, filosofia del
list data » test data, fast data
studium e » studium _, studium 1, studium 8
studium 3 » studium _, studium 1, studium 8

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 e) OR (studium 3)) ((filosofia y) OR (filosofia e)) literatura.
• The words AND, OR and NOT may confuse the search; try adding quotes: "list data ((studium e) OR (studium 3)) ((filosofia y) or (filosofia e)) literatura".
• Adding a wildcard symbol may retrieve word variants: list data ((studium e) OR (studium 3)) ((filosofia y) or (filosofia e)) literatura*.
