Perhaps you should try some spelling variations:
ii literatura » ii literatur, ii literature, iii literature
filosofia ii » filosofia di, filosofica di, filosofia de
sets scaled » sets scale, sets scales, less scaled
studien des » studien der, studie des, studien aus
studien de » studien der, studien die, 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 des))) OR (((studien de) OR (studien des))r)) filosofia ii literatura.
• The words AND, OR and NOT may confuse the search; try adding quotes: "sets scaled ((((studien de) OR (studien des))) or (((studien de) OR (studien des))r)) filosofia ii literatura".
• Adding a wildcard symbol may retrieve word variants: sets scaled ((((studien de) OR (studien des))) or (((studien de) OR (studien des))r)) filosofia ii literatura*.
