Perhaps you should try some spelling variations:
based studien » basedow studien, based student, band studien
based studies » based study
die filosofia » di filosofia, de filosofia, e filosofia
la literatura » la litterature, a literature
filosofia la » filosofia da, filosofia le, filosofica da

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "sets ((based studien) OR (based studies)) die filosofia la literatura".
• Adding a wildcard symbol may retrieve word variants: sets ((based studien) OR (based studies)) die filosofia la literatura*.
