Perhaps you should try some spelling variations:
a literatura » la literatura, a literature, y literatura
studies die » studie die, studien die, studies does
filosofia a » filosofia da, filosofia la, filosofia e
best scale » bast scale, rest scale, burst scale
studies de » studies der, studies doe, studies due

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: "best scale ((studies de) OR (studies die)) filosofia a literatura".
• Adding a wildcard symbol may retrieve word variants: best scale ((studies de) OR (studies die)) filosofia a literatura*.
