doi chieu » doc hieu, doi chi, ho chieu
trung cua » truong cua, trung tuan, trung cap
van phong » van dong, hai phong
van cong » van dong, phan cong, van duong

• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (doi chieu)) xanh - thanh trung cua ((van cong) OR (van phong)) anh luan ban~.
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (doi chieu)) xanh - thanh trung cua ((van cong) or (van phong)) anh luan ban*.
