Perhaps you should try some spelling variations:
del literatura » de literatura, pela literatura, da literatura
acute studien » acute studies, ante studien, aue studien
die filosofia » de filosofia, e filosofia, da filosofia
versus acute » versus active, versus actual
di filosofia » la filosofia, e filosofia

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: "versus acute studien ((die filosofia) OR (di filosofia)) del literatura*".
