• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu sang - ((canh doanh) OR (((chinh doanh) OR (kinh doanh)))) cua thong cong ban thanh toan~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu sang - ((canh doanh) or (((chinh doanh) OR (kinh doanh)))) cua thong cong ban thanh toan~".
• Adding a wildcard symbol may retrieve word variants: hoc chieu sang - ((canh doanh) or (((chinh doanh) OR (kinh doanh)))) cua thong cong ban thanh toan*.
