Perhaps you should try some spelling variations:
scale studium » schule studium, scale studies, duale studium
ii filosofia » la filosofia, e filosofia, a filosofia
di filosofia » la filosofia, e 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 studium ((ii filosofia) OR (di filosofia)) a literature".
• Adding a wildcard symbol may retrieve word variants: tests scale studium ((ii filosofia) OR (di filosofia)) a literature*.
