Perhaps you should try some spelling variations:
target studien » target studies, targets studies, target station
tests target » test target, tester target, test targets
studien die » studie die, studien der
filologia y » filologica e, biologia y, fonologia y
filosofia y » filosofia e, filosofia _, filosofia de
filologia e » filologica e, fisiologia e, filologici e

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 target studien die ((((filologia y) OR (filosofia y))) OR (filologia e)) literatura*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tests target studien die ((((filologia y) OR (filosofia y))) or (filologia e)) literatura*".
