Perhaps you should try some spelling variations:
filosofia de » filosofia del
dem studium » das studium, im studium, zum studium
filosofia y » filosofia e, filosofia _, filosofia da
studium la » studium a, studium als, studium das
text dem » text der, text des, text den

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: "text dem studium la ((filosofia y) OR (filosofia de)) literatura".
• Adding a wildcard symbol may retrieve word variants: text dem studium la ((filosofia y) OR (filosofia de)) literatura*.
