Perhaps you should try some spelling variations:
scale studies » case studies, scale study
der filosofia » di filosofia, da filosofia, em filosofia
de filosofia » di filosofia, la filosofia, a filosofia
e literatura » de literatura, y literatura, e literatur
e filosofia » la 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 ((((der filosofia) OR (e filosofia))) OR (de filosofia)) e literatura.
• The words AND, OR and NOT may confuse the search; try adding quotes: "best scale studies ((((der filosofia) OR (e filosofia))) or (de filosofia)) e literatura".
• Adding a wildcard symbol may retrieve word variants: best scale studies ((((der filosofia) OR (e filosofia))) or (de filosofia)) e literatura*.
