chu xanh » chu manh, chieu xanh, chua xang
trinh ve » trinh he, trinh va, trinh vi
cong dan » cong tan, huong dan, cong dong

• If you are trying to use Boolean operators, they must be ALL CAPS: chao chu xanh - hanh trinh ve dung ((cong dan) OR (cong san)) ((toan cau) OR (toan tap))~.
• Adding a wildcard symbol may retrieve word variants: chao chu xanh - hanh trinh ve dung ((cong dan) or (cong san)) ((toan cau) or (toan tap))*.
