Perhaps you should try some spelling variations:
die filologia » di filologia, de filologia, e filologia
y literatura » la literatura
tests frage » tests fake, tests free, tests fame
studien die » studie die, studien der
filologia y » filologia e, filologica e, filosofia y
tests face » tests fake, tests fame, tests false

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 frage) OR (tests face)) studien die filologia y literatura".
• Adding a wildcard symbol may retrieve word variants: ((tests frage) OR (tests face)) studien die filologia y literatura*.
