• The words AND, OR and NOT may confuse the search; try adding quotes: "toc hieu manh - hanh tranh ((cua thong) OR (cua thuong)) dong ((thanh toan) or (thanh san)) cau~".
• Adding a wildcard symbol may retrieve word variants: toc hieu manh - hanh tranh ((cua thong) OR (cua thuong)) dong ((thanh toan) or (thanh san)) cau*.
