• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((hieu manh) OR (chieu xanh)) - thanh truong ((ca dung) OR (cu dung)) cong tap quan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hieu manh) or (chieu xanh)) - thanh truong ((ca dung) OR (cu dung)) cong tap quan cau*".
