• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thieu tinh) OR (chieu tinh)) - doanh doanh cua thong ((cong van) OR (cong vang)) tuan mau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu tinh) OR (chieu tinh)) - doanh doanh cua thong ((cong van) or (cong vang)) tuan mau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu tinh) OR (chieu tinh)) - doanh doanh cua thong ((cong van) or (cong vang)) tuan mau*.
