• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu tinh)) - hanh tranh hoac khong cang ((tan than) OR (ban thanh)) cap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu tinh)) - hanh tranh hoac khong cang ((tan than) or (ban thanh)) cap".
