Perhaps you should try some spelling variations:
ii filosofia » di filosofia, la filosofia, e filosofia
studium ii » studium im, studium i, studium die
test dem » test der, test de, nebst dem
test des » test der, test test

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: "((test dem) OR (test des)) studium ii filosofia _ literatura".
• Adding a wildcard symbol may retrieve word variants: ((test dem) OR (test des)) studium ii filosofia _ literatura*.
