Perhaps you should try some spelling variations:
scale studies » case studies, scale study
la literatura » la litterature, a literature
da filosofia » la filosofia, di filosofia, de filosofia
a filosofia » la filosofia, e filosofia, di filosofia
best scale » bast scale, rest scale, burst scale

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: best scale studies ((da filosofia) OR (a filosofia)) la literatura*.
