Perhaps you should try some spelling variations:
la literatura » la litterature, a literature
filosofia la » filosofia da, filosofia le, filosofica da
studies die » studie die, studien die, studies does
test table » test tables, tests table, test tabelle
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: "test table ((studies de) OR (studies die)) filosofia la literatura".
• Adding a wildcard symbol may retrieve word variants: test table ((studies de) OR (studies die)) filosofia la literatura*.
