hanh trinh » canh tranh, hanh chinh
trinh cua » tinh cua, trinh luat, trinh quan
dong cong » duong cong, dung cong, dang cong
thanh hoa » thanh pho
ho chieu » theo chieu, hoc thieu, doi chieu

• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - hanh trinh cua dong cong ((((tinh toan) OR (thanh hoa))) OR (ban than)) cau~.
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - hanh trinh cua dong cong ((((tinh toan) or (thanh hoa))) or (ban than)) cau*.
