Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
thanh dung » thanh duong, thanh tung, hanh dung
thanh hung » thanh huong, thanh tung, thanh trung
trong dan » trong dang, trong san, trong tan
ho chieu » theo chieu, hoc thieu, doi chieu
va dung » van dung, va duong, vat dung

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

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