Perhaps you should try some spelling variations:
thanh phan » thanh pho, thanh toan, thanh hai
cua triet » cua viet, su triet, va triet
ky dang » ky nang
ky danh » ky anh
hieu ve » hieu va, hieu van
cac duc » cac du, cao duc, cac dac
su sac » su sach, su cac, su xac
ve cac » va cac, vien cac

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sac ((ky dang) OR (ky danh)) xa hoi. hieu ve cac duc va ((thanh phan) or (thanh san)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ((ky dang) OR (ky danh)) xa hoi. hieu ve cac duc va ((thanh phan) OR (thanh san)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ((ky dang) OR (ky danh)) xa hoi. hieu ve cac duc va ((thanh phan) or (thanh san)) cua triet".
• Adding a wildcard symbol may retrieve word variants: su sac ((ky dang) OR (ky danh)) xa hoi. hieu ve cac duc va ((thanh phan) or (thanh san)) cua triet*.
