Perhaps you should try some spelling variations:
del literatura » de literatura, pela literatura, e literatura
da literatura » la literatura, a literatura, de literatura
a filosofia » la filosofia, e filosofia, di filosofia
studium a » studium am, studium ad, studium _

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: ((suite _) OR (quite _)) studium a filosofia ((del literatura) OR (da literatura)).
• Adding a wildcard symbol may retrieve word variants: ((suite _) or (quite _)) studium a filosofia ((del literatura) or (da literatura))*.
