• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chua xang) OR (((chieu xanh) OR (chieu tinh)))) - thanh trung cua nhung cong van toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chua xang) or (((chieu xanh) OR (chieu tinh)))) - thanh trung cua nhung cong van toan cao~".
• Adding a wildcard symbol may retrieve word variants: theo ((chua xang) or (((chieu xanh) OR (chieu tinh)))) - thanh trung cua nhung cong van toan cao*.
