• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (so sach)) ky nang x hoi. hieu ve cam tuc ((van hanh) OR (van anh)) vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) or (so sach)) ky nang x hoi. hieu ve cam tuc ((van hanh) OR (van anh)) vi cua triet*".
