• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu xanh - thanh trung ((ca dang) OR (cac dang)) cong ((ban than) OR (ban hang)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu xanh - thanh trung ((ca dang) OR (cac dang)) cong ((ban than) or (ban hang)) cau*".
