• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((((chieu sang) OR (hieu lang))) or (chinh sach)) - hanh tang cua dung cong thanh toan tap~".
• Adding a wildcard symbol may retrieve word variants: ho ((((chieu sang) OR (hieu lang))) or (chinh sach)) - hanh tang cua dung cong thanh toan tap*.
