hien hanh » dieu hanh
tranh cua » doanh cua, manh cua

cong van » cong vang, cong san, song van
van toan » van tuan, van tan, van thanh

• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((((thien hach) OR (thien thanh))) OR (hien hanh)) - canh tranh cua nhung cong van toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((((thien hach) OR (thien thanh))) or (hien hanh)) - canh tranh cua nhung cong van toan tap~".
• Adding a wildcard symbol may retrieve word variants: hoc ((((thien hach) OR (thien thanh))) or (hien hanh)) - canh tranh cua nhung cong van toan tap*.
