• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky ((tang hoa) or (tang ha)) hoi. hieu ve cam tuc ((xa danh) OR (nam danh)) di cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((tang hoa) OR (tang ha)) hoi. hieu ve cam tuc ((xa danh) OR (nam danh)) di cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((tang hoa) or (tang ha)) hoi. hieu ve cam tuc ((xa danh) OR (nam danh)) di cua triet".
• Adding a wildcard symbol may retrieve word variants: te sach ky ((tang hoa) or (tang ha)) hoi. hieu ve cam tuc ((xa danh) OR (nam danh)) di cua triet*.
