• If you are trying to use Boolean operators, they must be ALL CAPS: doi chinh sach - thanh trung cap han tong dan ((((hang cau) OR (nhung cau))) OR (hang dau))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chinh sach - thanh trung cap han tong dan ((((hang cau) OR (nhung cau))) or (hang dau))*".
