• If you are trying to use Boolean operators, they must be ALL CAPS: ((doi chieu) OR (hoc thieu)) xanh - thanh trung cua tong ((cong anh) OR (cong danh)) tuan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doi chieu) or (hoc thieu)) xanh - thanh trung cua tong ((cong anh) OR (cong danh)) tuan ban~".
• Adding a wildcard symbol may retrieve word variants: ((doi chieu) or (hoc thieu)) xanh - thanh trung cua tong ((cong anh) OR (cong danh)) tuan ban*.
