Perhaps you should try some spelling variations:
die filosofia » di filosofia, de filosofia, da filosofia
da literatura » la literatura, a literatura, na literatura
de literatura » de litterature, la literatura, y literatura
table state » stable state, tables state, table stats
e filosofia » la filosofia
test table » test tables, tests table, test tabelle

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