• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ky nang ro hai. hieu ve cam ((xuc van) OR (duc van)) hanh thai ((cua triet) OR (cua viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ky nang ro hai. hieu ve cam ((xuc van) or (duc van)) hanh thai ((cua triet) OR (cua viet))".
