mot chieu » doi chieu, ho chieu

anh nang » ganh nang, anh bang, anh dang
nang cua » mang cua, hang cua, nang dua
dan toan » van toan, manh toan, xuan toan

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