Perhaps you should try some spelling variations:
a literatura » la literatura, a literature, y literatura
filosofia a » filosofia da, filosofia la, filosofia e
lists das » list das, lists dns, lists dates
studium y » studium 3, studium 8, studium 5
studium 1 » studium 3, studium 8, studium im

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: lists das ((studium y) OR (((studium 1) OR (studium _)))) filosofia a literatura.
• Adding a wildcard symbol may retrieve word variants: lists das ((studium y) or (((studium 1) or (studium _)))) filosofia a literatura*.
