• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - thanh trung ((cua thong) or (cua truong)) thong ((san than) OR (sang than)) cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - thanh trung ((cua thong) or (cua truong)) thong ((san than) OR (sang than)) cau*.
