• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (theo chieu)) xanh - hanh tranh cua dang ((cong tap) or (cong tac)) toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (theo chieu)) xanh - hanh tranh cua dang ((cong tap) or (cong tac)) toan ban*.
