Perhaps you should try some spelling variations:
ii literatura » ii literatur, ii literature, iii literature
tests stable » sets stable, test table, tests scale
filosofia ii » filosofia di, filosofica di, filosofia de
tests table » test tables, results table, test suitable
e filosofia » la filosofia
studien e » studien es, studien _, studien 3

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 e filosofia ii literatura*".
