Perhaps you should try some spelling variations:
moi nganh » khoi nganh, hoc nganh, moi ngay
cau triet » cau trieu, su triet, cua triet
nganh ky » nganh y, nganh xay, hanh ky
van hanh » van thanh, ban hanh, van anh
nang xa » nang x, lang xa, nang ma
van cac » van cau, van bac, dan cac
van hac » van hoc, van ha, van hai
va danh » va dinh, va dan, va hanh
vi cau » va cau, ve cau, di cau

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

• Performing a fuzzy search may retrieve terms with similar spellings: moi nganh ky nang xa hoi. hieu ((van cac) OR (van hac)) du ((van hanh) or (va danh)) vi cau triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: moi nganh ky nang xa hoi. hieu ((van cac) OR (van hac)) du ((van hanh) OR (va danh)) vi cau triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "moi nganh ky nang xa hoi. hieu ((van cac) OR (van hac)) du ((van hanh) or (va danh)) vi cau triet".
• Adding a wildcard symbol may retrieve word variants: moi nganh ky nang xa hoi. hieu ((van cac) OR (van hac)) du ((van hanh) or (va danh)) vi cau triet*.
