Perhaps you should try some spelling variations:
die filosofica » de filosofia, e filosofica, vida filosofica
sets locales » retos locales, sets local, et locales
di filosofia » la filosofia, e filosofia
sets scales » sets scale, sets scaled, sites scales

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 scales) OR (sets locales)) studien ((die filosofica) OR (di filosofia)) a literature.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((sets scales) or (sets locales)) studien ((die filosofica) OR (di filosofia)) a literature".
• Adding a wildcard symbol may retrieve word variants: ((sets scales) or (sets locales)) studien ((die filosofica) OR (di filosofia)) a literature*.
