mot chieu » doi chieu, ho chieu
cua duong » cua dong, cua huong, qua duong
anh nang » ganh nang, anh bang, anh dang

• If you are trying to use Boolean operators, they must be ALL CAPS: ((mot chieu) OR (theo chieu)) xanh - anh nang cua duong cong tan ((toan tap) OR (toan cao))~.
• Adding a wildcard symbol may retrieve word variants: ((mot chieu) or (theo chieu)) xanh - anh nang cua duong cong tan ((toan tap) or (toan cao))*.
