• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) OR (chieu xanh)) - anh nang cua dung dong thanh ((toan tap) or (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) OR (chieu xanh)) - anh nang cua dung dong thanh ((toan tap) or (toan cao))*.
