Perhaps you should try some spelling variations:
die filosofia » di filosofia, e filosofia, da filosofia
table studie » table studies, cable studies, table study
de filosofia » e filosofia, di filosofia, la filosofia
tests table » test tables, results table, test suitable

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 studie ((die filosofia) OR (de filosofia)) a literature*".
