Perhaps you should try some spelling variations:
van nhan » van phan, van thanh, danh nhan
vien cuc » vien cac, dien cuc, viec cua
cuc tieu » muc tieu, cac tieu, cach tieu
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
bao suc » cao suc, bao thuc
bao luc » bao thuc
sac 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) or (cac ky)) nang xa hoi. hieu va ((bao suc) OR (bao luc)) van nhan vien cuc tieu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sac ky) OR (cac ky)) nang xa hoi. hieu va ((bao suc) OR (bao luc)) van nhan vien cuc tieu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sac ky) or (cac ky)) nang xa hoi. hieu va ((bao suc) OR (bao luc)) van nhan vien cuc tieu".
• Adding a wildcard symbol may retrieve word variants: thu ((sac ky) or (cac ky)) nang xa hoi. hieu va ((bao suc) OR (bao luc)) van nhan vien cuc tieu*.
