• The words AND, OR and NOT may confuse the search; try adding quotes: "((mot chieu) or (hoc thieu)) xanh - hanh chinh cua hang cong san ((tan cao) OR (tay cao))~".
• Adding a wildcard symbol may retrieve word variants: ((mot chieu) or (hoc thieu)) xanh - hanh chinh cua hang cong san ((tan cao) OR (tay cao))*.
