• If you are trying to use Boolean operators, they must be ALL CAPS: te ((((sach tu) OR (cach tu))) OR (sach thu)) nang xa hoi. hieu va cao duc van hanh tai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((((sach tu) OR (cach tu))) or (sach thu)) nang xa hoi. hieu va cao duc van hanh tai cua triet".
