• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - ((canh tranh) OR (anh dung)) luan ((dong cong) OR (duong cong)) tac than cap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((canh tranh) or (anh dung)) luan ((dong cong) OR (duong cong)) tac than cap*".
