Perhaps you should try some spelling variations:
iii literature » ii literature, iii literatur, viii literatur
scale studien » scale studies, scale student, duale studien
ii literatura » ii literatur, ii literature, vii literature
tests scale » tests stable, sets scale, tests safe
studien la » studien lap, studien a, studien l

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 la filosofia ((ii literatura) OR (iii literature))*".
