Perhaps you should try some spelling variations:
chieu sach » chinh sach, chieu sang, chieu xanh
duong manh » duong van
thanh tra » thanh toan, thanh hoa
cong manh » cong danh, cong thanh, hoang manh
van dung » van dong, xay dung, tin dung
toan cao » toan ban, toan tap
tra van » tran van, ta van, trang van

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

• Performing a fuzzy search may retrieve terms with similar spellings: theo ((chieu sach) or (chiet tach)) - thanh tra van dung ((cong manh) OR (duong manh)) toan cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu sach) OR (chiet tach)) - thanh tra van dung ((cong manh) OR (duong manh)) toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu sach) or (chiet tach)) - thanh tra van dung ((cong manh) OR (duong manh)) toan cao".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu sach) or (chiet tach)) - thanh tra van dung ((cong manh) OR (duong manh)) toan cao*.
