Perhaps you should try some spelling variations:
y literatura » la literatura
studium das » studium des, studium der, studium die
filosofia y » filosofia e, filosofia _, filosofia de
studium la » studium a, studium als, studium _
quito a » quite a, quit a, quito _

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: ((quito a) OR (quite _)) ((studium la) OR (studium das)) filosofia y literatura.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((quito a) or (quite _)) ((studium la) OR (studium das)) filosofia y literatura".
• Adding a wildcard symbol may retrieve word variants: ((quito a) or (quite _)) ((studium la) OR (studium das)) filosofia y literatura*.
