Perhaps you should try some spelling variations:
theo chieu » theo tieu, theo chu, thi chieu
doanh luan » doanh nhan
cong thanh » dong thanh, cong trinh, cong tan
thanh phan » thanh pho, thanh san, thanh toan
dung cong » dung trong
ho chieu » hoc thieu, doi chieu, mot chieu
manh cua » doanh cua, ban cua

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 (theo chieu)) sach - canh ((manh cua) or (doanh luan)) dung cong thanh phan tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (theo chieu)) sach - canh ((manh cua) OR (doanh luan)) dung cong thanh phan tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (theo chieu)) sach - canh ((manh cua) or (doanh luan)) dung cong thanh phan tu*".
