Perhaps you should try some spelling variations:
dung cong » dung trong
cong data » cong dan, dong dat, cong danh
data phan » dam phan, sat phan, vat phan
ho chieu » theo chieu, hoc thieu, mot chieu
dat dung » dan dung, vat dung, da dung
van dan » van ban, ban dan, van dao
dan dat » dung dat, dong dat, dinh dat

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) or (toc thieu)) sang - van dan dat dung cong data phan tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (toc thieu)) sang - van dan dat dung cong data phan tu*.
