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