Perhaps you should try some spelling variations:
thuyet thanh » huyet thanh, thuyet trinh, huyen thanh
nganh luat » hanh luat
phung cong » nhung cong, phong cong, nhung chong
van phung » van phong, van hung, van chuong
luat van » luan van, luat dan, luat va
dan toan » van toan, dan than, manh toan

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

• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((thuyet thanh) OR (quyet thanh)) - nganh luat van phung cong ((dan toan) or (dan gian)) cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thuyet thanh) OR (quyet thanh)) - nganh luat van phung cong ((dan toan) OR (dan gian)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thuyet thanh) OR (quyet thanh)) - nganh luat van phung cong ((dan toan) or (dan gian)) cau".
• Adding a wildcard symbol may retrieve word variants: hoc ((thuyet thanh) OR (quyet thanh)) - nganh luat van phung cong ((dan toan) or (dan gian)) cau*.
