Perhaps you should try some spelling variations:
vida filosofica » da filosofia, fija filosofia, forma filosofica
de litterature » la litterature, et litterature
filosofica de » filosoficas de, filosofia de, filosofica da
studium vida » studium von, studium die, studium eine
test dualen » test doubles
des dualen » der dualen, des idealen

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: "((test dualen) OR (des dualen)) studium vida filosofica de litterature*".
