doi chieu » doc hieu, doi chi, ho chieu
tong cong » trong cong, cong cong, dung cong
hanh ban » thanh ban, hang ban, hanh san

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