• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (hoc hien)) xanh - ((doanh doanh) OR (toan doanh)) cua thuong cong tan toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (hoc hien)) xanh - ((doanh doanh) OR (toan doanh)) cua thuong cong tan toan tap~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (hoc hien)) xanh - ((doanh doanh) OR (toan doanh)) cua thuong cong tan toan tap*.
