Perhaps you should try some spelling variations:
thanh tinh » thanh binh, nhanh tinh, than kinh
duong manh » duong van
canh tinh » hanh tinh, manh tinh, canh tranh
qua tuong » qua trong, qua duong, cua truong
manh toan » thanh toan, anh tuan, tinh toan
cot lieu » co lieu, vat lieu, so lieu
toan cao » toan ban, toan tap
cu lieu » du lieu, tu lieu

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ((cu lieu) OR (cot lieu)) tinh - ((canh tinh) OR (thanh tinh)) qua tuong duong manh toan cao~.
• Adding a wildcard symbol may retrieve word variants: ((cu lieu) or (cot lieu)) tinh - ((canh tinh) or (thanh tinh)) qua tuong duong manh toan cao*.
