hanh tranh » canh tranh, hanh trinh, hanh trang
tranh cua » doanh cua, manh cua
cong cong » cong dong, trong cong, dung cong
cong san » cong tac
ban ban » ban banh, van ban, ban dan
can ban » van ban, toan ban

• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu tinh) OR (thien danh)) - hanh tranh cua cong cong san ((ban ban) OR (can ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu tinh) or (thien danh)) - hanh tranh cua cong cong san ((ban ban) OR (can ban))~".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu tinh) or (thien danh)) - hanh tranh cua cong cong san ((ban ban) OR (can ban))*.
