• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu danh - thanh trung cua nong thong ((quan thanh) or (((ban thanh) OR (ban hanh)))) tap~".
• Adding a wildcard symbol may retrieve word variants: theo tieu danh - thanh trung cua nong thong ((quan thanh) or (((ban thanh) OR (ban hanh)))) tap*.
