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