Perhaps you should try some spelling variations:
truong cong » trong cong, truong dong, truong long
trinh cua » trinh luat, trinh quan, trinh luan
tinh cua » sinh cua, tinh chat, tranh cua
cong dan » cong san, cong tan, huong dan
dan khan » dan khanh, dan chan, dan than
khan cap » khan ap, than cap, khoan cam
ho lieu » so lieu, ho kieu, ho chieu
co lieu » cot lieu, co hieu, so lieu

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 lieu) OR (co lieu)) tinh - hanh ((trinh cua) OR (tinh cua)) truong cong dan khan cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho lieu) or (co lieu)) tinh - hanh ((trinh cua) OR (tinh cua)) truong cong dan khan cap~".
• Adding a wildcard symbol may retrieve word variants: ((ho lieu) or (co lieu)) tinh - hanh ((trinh cua) OR (tinh cua)) truong cong dan khan cap*.
