ho chieu » theo chieu, doi chieu, mot chieu
manh cua » doanh cua, ban cua
cua dang » cua cong, cua ban

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