Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
thanh dung » thanh duong, thanh tung, thanh hung
cua truong » cua trung, xuan truong, cac truong
cua trong » cua trung, qua trong, ca trong
ho chieu » theo chieu, hoc thieu, doi chieu
dan than » dan chan, ban than, van than

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 ((cua trong) OR (cua truong)) cong ((dan than) or (tinh toan)) ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - thanh dung ((cua trong) OR (cua truong)) cong ((dan than) OR (tinh toan)) ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - thanh dung ((cua trong) OR (cua truong)) cong ((dan than) or (tinh toan)) ban".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - thanh dung ((cua trong) OR (cua truong)) cong ((dan than) or (tinh toan)) ban*.
