Perhaps you should try some spelling variations:
thanh dung » thanh duong, thanh tung, thanh hung
hoc thieu » toc thieu, hoc hien
trong dan » trong dang, trong san, trong tan
ho chieu » theo chieu, doi chieu, mot chieu
van dung » van dong, xay dung, tin dung
va dung » va duong, vat dung, va ung
dan van » dang van, doan van, dao van

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