Perhaps you should try some spelling variations:
pela literatura » pena literatura, la literatura, a literatura
filosofia pela » filosofia della, filosofia del, filosofia para
texten das » texten des, text das, texten aus
texten der » texte der, text der
studium la » studium a, studium als, studium das

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 das) OR (texten der)) studium la filosofia pela literatura*.
