Perhaps you should try some spelling variations:
chiet tach » chieu sach
dang cong » dung cong
tinh cua » trinh cua, tinh chat, tranh cua
sinh cua » manh cua, dinh cuu, sinh va
cong dan » cong san, cong tan, huong dan
dan can » dan chan, dan canh, dan ca
can cau » van cau, ban cau, ca cau

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 ((chinh sach) OR (chiet tach)) - hanh ((tinh cua) OR (sinh cua)) dang cong dan can cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chinh sach) or (chiet tach)) - hanh ((tinh cua) OR (sinh cua)) dang cong dan can cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chinh sach) or (chiet tach)) - hanh ((tinh cua) OR (sinh cua)) dang cong dan can cau*.
