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