Perhaps you should try some spelling variations:
e filosofiche » ve filosoficke, e filosofica, e filosofie
a literatura » la literatura, a literature, a literatur
y literatura » la literatura
do studie » divo studie, die studie, do studios
studie e » studie 2, studie _, studie 1
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 studie e filosofiche ((a literatura) OR (y literatura))".
• Adding a wildcard symbol may retrieve word variants: test do studie e filosofiche ((a literatura) OR (y literatura))*.
