Perhaps you should try some spelling variations:
e filosofiche » ve filosoficke, e filosofie, e filosofia
e filosofica » e filosofia, a filosofia, y filosofia
a literatura » la literatura, a literature, y literatura
de studie » die studie, de studio, e studie
test de » test der, test des, est 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 de studie ((e filosofica) OR (e filosofiche)) a literatura*".
