• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (((chieu tinh) OR (trieu tinh)))) - thanh trung cua nhung tuong dan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) or (((chieu tinh) OR (trieu tinh)))) - thanh trung cua nhung tuong dan toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) or (((chieu tinh) OR (trieu tinh)))) - thanh trung cua nhung tuong dan toan cau*.
