• The words AND, OR and NOT may confuse the search; try adding quotes: "((doc hieu) or (theo chieu)) sang - ((hanh manh) OR (hoang manh)) cua bang cong van tan tat~".
• Adding a wildcard symbol may retrieve word variants: ((doc hieu) or (theo chieu)) sang - ((hanh manh) OR (hoang manh)) cua bang cong van tan tat*.
