Perhaps you should try some spelling variations:
am filosofica » a filosofia, em filosofia, af filosofiska
la literatura » la litterature, a literature
e filosofica » e filosofia, e filosofiche, a filosofia
dem studium » das studium, im studium, zum studium
test dem » test der, test des, test de

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 studium ((am filosofica) OR (e filosofica)) la literatura".
• Adding a wildcard symbol may retrieve word variants: test dem studium ((am filosofica) OR (e filosofica)) la literatura*.
