• The words AND, OR and NOT may confuse the search; try adding quotes: "chao chieu xanh - hanh trinh cua ((thong cong) or (thong thong)) ((manh toan) OR (thanh toan)) cau~".
• Adding a wildcard symbol may retrieve word variants: chao chieu xanh - hanh trinh cua ((thong cong) or (thong thong)) ((manh toan) OR (thanh toan)) cau*.
