Perhaps you should try some spelling variations:
versus acute » versus active, versus actual
dd filosofia » di filosofia, de filosofia, da filosofia
e literatura » de literatura, y literatura, e literatur
tests acute » testis acute, testing acute, tests active
filosofia e » filosofia de, filosofia del
studien dd » studies dd, studien der, studien die

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 acute) OR (versus acute)) studien dd filosofia e literatura".
• Adding a wildcard symbol may retrieve word variants: ((tests acute) OR (versus acute)) studien dd filosofia e literatura*.
