Perhaps you should try some spelling variations:
filosofica di » filosofia di, filosofica da, filosofico di
filosofia ii » filosofia di, filosofia de, filosofia e
sets scaled » sets scale, sets scales, less scaled
studien der » studie der, studenten der
studien de » studien die, studien des, studien dd

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 scaled ((studien de) OR (studien der)) ((filosofia ii) OR (filosofica di)) literatura.
• The words AND, OR and NOT may confuse the search; try adding quotes: "sets scaled ((studien de) or (studien der)) ((filosofia ii) OR (filosofica di)) literatura".
• Adding a wildcard symbol may retrieve word variants: sets scaled ((studien de) or (studien der)) ((filosofia ii) OR (filosofica di)) literatura*.
