Perhaps you should try some spelling variations:
chieu sach » chinh sach, chieu sang, chieu xanh
nhung cong » dung cong, thong cong, hang cong
tranh cua » doanh cua
manh cua » doanh cua, ban cua
cong tan » cong tac, cong san, cong thanh
tan toan » tan tran, tap toan, van toan
toan tap » toan ban

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: hoc ((chieu sach) OR (chiet tach)) - hanh ((tranh cua) OR (manh cua)) nhung cong tan toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu sach) OR (chiet tach)) - hanh ((tranh cua) or (manh cua)) nhung cong tan toan tap~".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu sach) OR (chiet tach)) - hanh ((tranh cua) or (manh cua)) nhung cong tan toan tap*.
