Perhaps you should try some spelling variations:
es filosofia » e filosofia, la filosofia, di filosofia
em filosofia » e filosofia, la filosofia, di filosofia
bast scale » best scale, basin scale, based scale
vast scale » coast scale, best scale, just scale
literatur » literature

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) OR (vast scale)) studien ((es filosofia) OR (em filosofia)) e literatur.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((bast scale) OR (vast scale)) studien ((es filosofia) or (em filosofia)) e literatur".
• Adding a wildcard symbol may retrieve word variants: ((bast scale) OR (vast scale)) studien ((es filosofia) or (em filosofia)) e literatur*.
