cong cong » cong dong, trong cong, dung cong
theo chu » theo chieu, cho chu, chao chu
chu xanh » chu manh, chieu xanh, chua xang
cong tan » cong tac, cong san, cong thanh
toan tai » toan tap, doanh tai, toan cao
toan ban » van ban

• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu xanh - ((hanh tang) OR (hanh mang)) cua cong cong tan ((toan tai) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xanh - ((hanh tang) OR (hanh mang)) cua cong cong tan ((toan tai) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - ((hanh tang) OR (hanh mang)) cua cong cong tan ((toan tai) or (toan ban))*.
