• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) OR (chieu sang)) - hanh tranh cua nhung dong thanh ((toan cau) or (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sach) OR (chieu sang)) - hanh tranh cua nhung dong thanh ((toan cau) or (toan cao))*.
