Perhaps you should try some spelling variations:
scale student » late student, scale study, male students
scale studies » scale study
da literatura » la literatura, a literatura, de literatura
e filosofica » e filosofia, e filosofiche, y filosofia
a filosofia » la filosofia, e filosofia, di filosofia

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: set ((scale student) OR (scale studies)) ((e filosofica) OR (a filosofia)) da literatura.
• The words AND, OR and NOT may confuse the search; try adding quotes: "set ((scale student) OR (scale studies)) ((e filosofica) or (a filosofia)) da literatura".
• Adding a wildcard symbol may retrieve word variants: set ((scale student) OR (scale studies)) ((e filosofica) or (a filosofia)) da literatura*.
