dong cong » duong cong, dung cong, dang cong
ho chieu » hoc thieu, doi chieu, mot chieu
tung cua » trung cua, tuong cua, dung cua
cua dong » chua dong, cua cong, cua dang
cong tan » cong tac, cong san, cong thanh

• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (theo chieu)) xanh - thanh tung cua dong cong tan ((tvan cau) OR (van cau))~.
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (theo chieu)) xanh - thanh tung cua dong cong tan ((tvan cau) or (van cau))*.
