• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu xanh) OR (chieu tinh)) - thanh truong ((cao thuong) OR (cho thuong)) cong san chan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu xanh) OR (chieu tinh)) - thanh truong ((cao thuong) or (cho thuong)) cong san chan cau*".
