• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - thanh trung cua ((((dung chung) OR (dung ung))) OR (doan phuong)) ban thanh cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - thanh trung cua ((((dung chung) OR (dung ung))) or (doan phuong)) ban thanh cap~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - thanh trung cua ((((dung chung) OR (dung ung))) or (doan phuong)) ban thanh cap*.
