• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (theo tieu)) xanh - ((canh doanh) OR (hanh doanh)) va nhung phong van toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (theo tieu)) xanh - ((canh doanh) OR (hanh doanh)) va nhung phong van toan cau*.
