Perhaps you should try some spelling variations:
qua nhan » cua nhan, qua nhat, qua phan
nhan luc » nang luc
ban hang » ngan hang
va triet » va thiet, va trien, ve triet
su triet » su viet, su tien, ve triet
thu sac » thu sach, thu san, thu xac
nang xa » nang x, lang xa, nang ma
sac ky » cac ky, sai ky

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

• Performing a fuzzy search may retrieve terms with similar spellings: thu sac ky nang xa hoi. hieu qua nhan luc ((ban hanh) OR (ban hang)) vi ((va triet) or (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac ky nang xa hoi. hieu qua nhan luc ((ban hanh) OR (ban hang)) vi ((va triet) OR (su triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sac ky nang xa hoi. hieu qua nhan luc ((ban hanh) OR (ban hang)) vi ((va triet) or (su triet))".
• Adding a wildcard symbol may retrieve word variants: thu sac ky nang xa hoi. hieu qua nhan luc ((ban hanh) OR (ban hang)) vi ((va triet) or (su triet))*.
