Perhaps you should try some spelling variations:
de filosofia » di filosofia, la filosofia, a filosofia
y literatura » la literatura
e filosofia » la filosofia
list das » ist das, list des, kleist das
bist das » ist das, geist das, brust das

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((list das) OR (bist das)) studio ((de filosofia) OR (e filosofia)) y literatura.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((list das) OR (bist das)) studio ((de filosofia) or (e filosofia)) y literatura".
• Adding a wildcard symbol may retrieve word variants: ((list das) OR (bist das)) studio ((de filosofia) or (e filosofia)) y literatura*.
