Perhaps you should try some spelling variations:
eestudio del » estudio de, estudios del, studio del
y literatura » la literatura
estudio del » estudios del, estudio de, studio della
estudios de » estudio de
filosofia y » filosofia e, filosofia _, filosofia de
list das » ist das, list des, bist 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 ((estudio del) OR (((eestudio del) OR (estudios de)))) filosofia y literatura.
• Adding a wildcard symbol may retrieve word variants: list das ((estudio del) or (((eestudio del) or (estudios de)))) filosofia y literatura*.
