• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (ho chieu)) xanh - anh doanh cua ban cong van ((tan cau) OR (van cau))~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (ho chieu)) xanh - anh doanh cua ban cong van ((tan cau) OR (van cau))*.
