• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo yeu) OR (cho thue)) sach - hanh trung cua thuong cong ((dan toan) OR (manh toan)) cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo yeu) or (cho thue)) sach - hanh trung cua thuong cong ((dan toan) OR (manh toan)) cao*".
