• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo may) OR (theo mau)) tinh - nhanh hang cua tong ((cong dan) OR (cong tac)) toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo may) OR (theo mau)) tinh - nhanh hang cua tong ((cong dan) or (cong tac)) toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((theo may) OR (theo mau)) tinh - nhanh hang cua tong ((cong dan) or (cong tac)) toan ban*.
