• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - ((thanh tuong) OR (thanh thuong)) va nhung ((cong dan) OR (huong dan)) toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((thanh tuong) OR (thanh thuong)) va nhung ((cong dan) or (huong dan)) toan cao".
