Perhaps you should try some spelling variations:
studenten die » studenten der, studenten des, studenten und
die filosofia » di filosofia, de filosofia, e filosofia
e literatura » de literatura, y literatura, e literatur
tests scale » tests stable, tests safe, tests shall
filosofia e » filosofia de, filosofia del
sets scale » sets scaled, sets scales, set scale

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: "((tests scale) OR (sets scale)) studenten die filosofia e literatura".
• Adding a wildcard symbol may retrieve word variants: ((tests scale) OR (sets scale)) studenten die filosofia e literatura*.
