Perhaps you should try some spelling variations:
cong thanh » dong thanh, cong trinh, truong thanh
tieu danh » dieu danh, tiep danh, thien danh
hanh tang » hanh trang, anh tang, hanh tung
hanh mang » nhanh mang, hanh trang, nhanh lang
cua dang » cua cong, cua ban
cong tan » cong tac, cong san, cong ty
toan cao » toan ban, toan tap

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: theo tieu danh - ((hanh tang) OR (hanh mang)) cua dang ((cong thanh) OR (cong tan)) toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu danh - ((hanh tang) or (hanh mang)) cua dang ((cong thanh) OR (cong tan)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: theo tieu danh - ((hanh tang) or (hanh mang)) cua dang ((cong thanh) OR (cong tan)) toan cao*.
