• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (vu khac)) ky nang doc hoi. hieu va cam tu van hanh vai ((cua tre) OR (cua triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) or (vu khac)) ky nang doc hoi. hieu va cam tu van hanh vai ((cua tre) OR (cua triet))*".
