• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chua tinh) OR (cuu tinh)) - hanh mang cua bang song ((van tan) OR (van tuan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chua tinh) or (cuu tinh)) - hanh mang cua bang song ((van tan) OR (van tuan)) cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chua tinh) or (cuu tinh)) - hanh mang cua bang song ((van tan) OR (van tuan)) cau*.
