• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((((chieu tinh) OR (lieu tinh))) or (trieu tinh)) - thanh cong cua nhung cong san toan ban~".
• Adding a wildcard symbol may retrieve word variants: theo ((((chieu tinh) OR (lieu tinh))) or (trieu tinh)) - thanh cong cua nhung cong san toan ban*.
