Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
trang cua » tranh cua, tang cua, thang cua
trung cua » truong cua, trung tuan, trung cap
cuong tap » luong tap, cong tac, luong tai
ho chieu » theo chieu, hoc thieu, doi chieu
cong tap » cong tac, cong tan, tong tap
quan tap » quan tai, quan lap, quan tam

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - hanh ((trang cua) OR (trung cua)) nhung ((cong tap) OR (cuong tap)) quan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - hanh ((trang cua) or (trung cua)) nhung ((cong tap) OR (cuong tap)) quan tap~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - hanh ((trang cua) or (trung cua)) nhung ((cong tap) OR (cuong tap)) quan tap*.
