Perhaps you should try some spelling variations:
duales studium » das studium
duale studien » duale studium, scale studien, dualen studium
die filologia » di filologia, de filologia, e filologia
y literatura » la literatura
filologia y » filologia e, filologica e, filosofia y
testo » test, tests, texto

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: testo ((duales studium) OR (duale studien)) die filologia y literatura.
• Adding a wildcard symbol may retrieve word variants: testo ((duales studium) or (duale studien)) die filologia y literatura*.
