Perhaps you should try some spelling variations:
la literatura » la litterature, a literature
da filosofia » la filosofia, di filosofia, de filosofia
a filosofia » la filosofia, e filosofia, di filosofia
do studium » d studium, das studium, dem studium
test do » test de, test d, test der

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 do studium ((da filosofia) OR (a filosofia)) la literatura*".
