Perhaps you should try some spelling variations:
vien cua » viec cua, dien cua, tien cua
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
suc van » su van, duc van, sac van
luc van » luoc van, luu van, duc van
sac ky » sai ky
ve cao » va cao, ve bao, ve cac
cua te » cua tu

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