Perhaps you should try some spelling variations:
filosofica da » filosofia da, filosofia de, filosofia di
filosofia la » filosofia da, filosofia das, filosofia uma
filosofia le » filosofia de, filosofia e, filosofia del
des studium » des studiums, das studium, dem studium
texten des » texten der, texte des, text des
studium 8 » studium _, studium 1, studium 3

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: texten des studium 8 ((((filosofia la) OR (filosofica da))) OR (filosofia le)) literatura*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "texten des studium 8 ((((filosofia la) OR (filosofica da))) or (filosofia le)) literatura*".
