Perhaps you should try some spelling variations:
scale studien » scale studies, scale student, duale studien
filosofia la » filosofia da, filosofica da, filosofia das
filosofia le » filosofia de, filosofia e, filosofia del
filosofia a » filosofia da, filosofia e, filosofia _
sets scale » sets scaled, sets scales, set scale
studien de » studien der, studien die, studien des

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: sets scale studien de ((filosofia a) OR (((filosofia la) OR (filosofia le)))) literature.
• The words AND, OR and NOT may confuse the search; try adding quotes: "sets scale studien de ((filosofia a) or (((filosofia la) OR (filosofia le)))) literature".
• Adding a wildcard symbol may retrieve word variants: sets scale studien de ((filosofia a) or (((filosofia la) OR (filosofia le)))) literature*.
