filosofica la » filosofica da, filosofia la, filosofica e
filosofia da » filosofia de, filosofia del, filosofia e
test state » test stated, test stage, best state
studied e » studied _, studied 3, studied 5

• The words AND, OR and NOT may confuse the search; try adding quotes: "test state studied e ((filosofica la) OR (filosofia da)) literatura".
• Adding a wildcard symbol may retrieve word variants: test state studied e ((filosofica la) OR (filosofia da)) literatura*.
