Perhaps you should try some spelling variations:
text modules » test modules, ext modules, et modules
a literatura » la literatura, a literature, y literatura
e filosofia » la filosofia
filosofia a » filosofia da, filosofia la, filosofia e
text dates » text datei, text daten, text data
studium e » 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: ((text modules) OR (text dates)) studium e filosofia a literatura*.
