• If you are trying to use Boolean operators, they must be ALL CAPS: doc ((hieu xanh) OR (chieu xanh)) - thanh truong dai ((nhung cong) OR (dung cong)) manh toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((hieu xanh) OR (chieu xanh)) - thanh truong dai ((nhung cong) or (dung cong)) manh toan cao".
