Perhaps you should try some spelling variations:
duales studium » das studium
la literatura » la litterature, a literature
e filosofia » la filosofia
studium e » studium _, studium 1, studium 3
testo » test, tests, texto

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: "testo duales studium e filosofia ((y literatura) OR (la literatura))".
• Adding a wildcard symbol may retrieve word variants: testo duales studium e filosofia ((y literatura) OR (la literatura))*.
