Perhaps you should try some spelling variations:
table studies » cable studies, bible studies, eagle studies
die filosofia » di filosofia, de filosofia, da filosofia
e literatura » de literatura, y literatura, e literatur
tests table » test tables, results table, test suitable

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