Perhaps you should try some spelling variations:
ii literature » ii literatur, i literature, vii literatur
tests stable » sets stable, test table, tests scale
de filosofia » e filosofia, di filosofia, la filosofia
filosofia ii » filosofia di, filosofica di, filosofia de
tests table » test tables, results table, test suitable
studien de » studien der, studien die, studien des

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 stable) OR (tests table)) studien de filosofia ii literature*".
