Perhaps you should try some spelling variations:
scale studien » scale studies, scale student, duale studien
e literatura » de literatura, e literatur, a literatura
y literatura » la literatura
bast scale » best scale, vast scale, basin scale
studien la » studien lap, studien a, studien l

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

• If you are trying to use Boolean operators, they must be ALL CAPS: bast scale studien la filosofia ((e literatura) OR (y literatura))*.
