Perhaps you should try some spelling variations:
scale studies » case studies, scale study
div filosofia » di filosofia, de filosofia, da filosofia
la literatura » la litterature, a literature
studies div » studies die, studies drive, studies diet
vast scale » bast scale, coast scale, best scale

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "vast scale studies div filosofia ((y literatura) OR (la literatura))*".
