• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) or (hieu lang)) - thanh trung ((cua thuong) OR (cua phuong)) cong tac thanh chau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sang) or (hieu lang)) - thanh trung ((cua thuong) OR (cua phuong)) cong tac thanh chau*.
