Perhaps you should try some spelling variations:
acute studien » acute studies, ante studien, aue studien
filologica e » filologia e, filologici e, filosofica e
tests acute » testis acute, testing acute, versus acute
filologia y » filologia e, filosofia y, biologia y
studien di » studien die, studien dd, studien der

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: tests acute studien di ((filologia y) OR (filologica e)) literatura.
• Adding a wildcard symbol may retrieve word variants: tests acute studien di ((filologia y) or (filologica e)) literatura*.
