Perhaps you should try some spelling variations:
y literatura » la literatura
studium die » studium der, studium des
filosofia y » filosofia e, filosofia _, filosofia de
test forms » best forms, most forms, testing forms
list forms » lists forms, best forms, lowest forms
studium de » studium der, studium des, studium den

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: ((test forms) OR (list forms)) ((studium de) OR (studium die)) filosofia y literatura.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((test forms) OR (list forms)) ((studium de) or (studium die)) filosofia y literatura".
• Adding a wildcard symbol may retrieve word variants: ((test forms) OR (list forms)) ((studium de) or (studium die)) filosofia y literatura*.
