• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chua xang) OR (chuc nang)) - hanh tranh ((cua thuong) OR (cuu phuong)) duong anh tuan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chua xang) OR (chuc nang)) - hanh tranh ((cua thuong) or (cuu phuong)) duong anh tuan cau".
• Adding a wildcard symbol may retrieve word variants: theo ((chua xang) OR (chuc nang)) - hanh tranh ((cua thuong) or (cuu phuong)) duong anh tuan cau*.
