Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh trung » thanh trung, manh trung, danh trung
hanh trang » thanh trung, canh tranh, hanh trinh
ho chieu » theo chieu, hoc thieu, doi chieu
ung cong » dung cong, luong cong, duong cong
cong tac » cong ty
tac toan » tap toan, tam toan, hach toan
toan cau » toan cao, toan ban, toan tap

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((hanh trung) OR (hanh trang)) dap ung cong tac toan cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((hanh trung) OR (hanh trang)) dap ung cong tac toan cau*.
