hanh tinh » hanh trinh, nhanh tinh, thanh tinh
dang cong » dung cong
tinh cua » trinh cua, sinh cua, tinh chat
cua dang » cua cong, cua ban

• If you are trying to use Boolean operators, they must be ALL CAPS: ((doi chieu) OR (hoc thieu)) xanh - hanh tinh cua dang cong dan ((toan tap) OR (toan cao))~.
• Adding a wildcard symbol may retrieve word variants: ((doi chieu) or (hoc thieu)) xanh - hanh tinh cua dang cong dan ((toan tap) or (toan cao))*.
