• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu sang - canh tranh ((cua nhung) OR (cua dang)) cong manh ((toan cau) OR (toan cao))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sang - canh tranh ((cua nhung) or (cua dang)) cong manh ((toan cau) OR (toan cao))*".
