• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chu bang) OR (chuc nang)) - hanh trang ((cua thong) OR (cua thuong)) cong van khanh cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu bang) OR (chuc nang)) - hanh trang ((cua thong) or (cua thuong)) cong van khanh cau".
• Adding a wildcard symbol may retrieve word variants: theo ((chu bang) OR (chuc nang)) - hanh trang ((cua thong) or (cua thuong)) cong van khanh cau*.
