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

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 a) OR (filosofia e)) literature*".
