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