• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((chieu xanh) or (thien anh)) - hanh tranh cua tuong dong tan ((toan cau) OR (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: toc ((chieu xanh) or (thien anh)) - hanh tranh cua tuong dong tan ((toan cau) OR (toan tap))*.
