• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - thanh truong quan ((thong cong) or (trong cong)) van ((thanh lap) OR (thanh san))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sang - thanh truong quan ((thong cong) or (trong cong)) van ((thanh lap) OR (thanh san))*.
