• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu sach)) - thanh ((truong cao) OR (truong dai)) nhung cong ban than cap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu sach)) - thanh ((truong cao) OR (truong dai)) nhung cong ban than cap".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu sach)) - thanh ((truong cao) OR (truong dai)) nhung cong ban than cap*.
