Perhaps you should try some spelling variations:
scales studien » scale studien, scale studies, scale student
de filosofia » e filosofia, di filosofia, la filosofia
e literatura » de literatura, y literatura, a literatura
sets scales » sets scale, sets scaled, sets locales
studien de » studien der, studien die, studien des
literatura » literaturea
literatur » literature

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: "sets scales studien de filosofia ((e literatura) OR (e literatur))*".
