• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (vu sach)) ky nang ma hoi. hieu va ((cham tuc) OR (pham thuc)) xa danh te cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (vu sach)) ky nang ma hoi. hieu va ((cham tuc) OR (pham thuc)) xa danh te cua te~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (vu sach)) ky nang ma hoi. hieu va ((cham tuc) OR (pham thuc)) xa danh te cua te*.
