thong cong » trong cong, tong cong, thong thong
chua xang » chua nang, chuc nang, chu bang
doanh van » doan van, doanh va, doanh ban
cho chua » cho chu, cho cua, ho chua
toan cau » toan cao, toan ban, toan tap

• If you are trying to use Boolean operators, they must be ALL CAPS: cho chua xang - doanh van van ((nhung cong) OR (thong cong)) van ((van cau) OR (toan cau))~.
• Adding a wildcard symbol may retrieve word variants: cho chua xang - doanh van van ((nhung cong) or (thong cong)) van ((van cau) or (toan cau))*.
