Perhaps you should try some spelling variations:
scale studien » scale studies, scale student, duale studien
e filosofiche » ve filosoficke, e filosofie, e filosofia
da literatura » la literatura, a literatura, de literatura
e filosofica » e filosofia, a filosofia, y filosofia
tests scale » tests stable, sets scale, tests safe

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: "tests scale studien ((e filosofica) OR (e filosofiche)) da literatura*".
