Perhaps you should try some spelling variations:
e literature » e literatur, life literature, prose literature
tests state » tests static, tests stable, cysts state
filosofia e » filosofia de, filosofia del
test state » test stated, test stage, best state
studied 5 » studied _
studied 3 » studied _, studied 3.3

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((tests state) OR (test state)) ((studied 5) OR (studied 3)) filosofia e literature.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tests state) OR (test state)) ((studied 5) or (studied 3)) filosofia e literature".
• Adding a wildcard symbol may retrieve word variants: ((tests state) OR (test state)) ((studied 5) or (studied 3)) filosofia e literature*.
