hang nong » thang long, han tong
ho chinh » hoc chinh, cho chinh, hoa chinh

• If you are trying to use Boolean operators, they must be ALL CAPS: ho chinh sach - canh tranh cua ((nhung cong) OR (((hang cong) OR (hang nong)))) van toan cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chinh sach - canh tranh cua ((nhung cong) or (((hang cong) OR (hang nong)))) van toan cao*".
