Perhaps you should try some spelling variations:
e literatura » de literatura, y literatura, e literatur
tests table » test tables, results table, test suitable
studies die » studies does, studies dose, studies ds
studien die » studie die, studien der
filosofia e » filosofia de, filosofia del

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: "tests table ((studies die) OR (studien die)) filosofia e literatura".
• Adding a wildcard symbol may retrieve word variants: tests table ((studies die) OR (studien die)) filosofia e literatura*.
