Perhaps you should try some spelling variations:
nhan tien » nhan vien, nhan dien, phan tien
thu sac » thu sach, thu san, thu xac
nang xa » nang x, nang ma, mang xa
lang xa » lang ha, dang xay, lang van
hieu ve » hieu va, hieu van
bao suc » bao luc, cao suc, bao thuc
sac ky » cac ky, sai ky
ve bao » te bao, va bao
suc ca » suc cap, suc co, suc ma
cua tu » cua tuc, cua su, cua cu

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) OR (lang xa)) hoi. hieu ve bao suc ca nhan tien ((cua te) or (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac ky ((nang xa) OR (lang xa)) hoi. hieu ve bao suc ca nhan tien ((cua te) OR (cua tu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sac ky ((nang xa) OR (lang xa)) hoi. hieu ve bao suc ca nhan tien ((cua te) or (cua tu))".
• Adding a wildcard symbol may retrieve word variants: thu sac ky ((nang xa) OR (lang xa)) hoi. hieu ve bao suc ca nhan tien ((cua te) or (cua tu))*.
