Perhaps you should try some spelling variations:
nhan viec » nhan vien, nhan viet, nha viec
thu sac » thu sach, thu san, thu xac
nang xa » nang x, lang xa, nang ma
sac ky » cac ky, sai ky
ve cao » va cao, ve bao, ve co
ve cac » va cac, vien cac
suc va » tuc va, luc va, soc va
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 nang xa hoi. hieu ((ve cao) OR (ve cac)) ((suc va) or (duc va)) nhan viec cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac ky nang xa hoi. hieu ((ve cao) OR (ve cac)) ((suc va) OR (duc va)) nhan viec cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sac ky nang xa hoi. hieu ((ve cao) OR (ve cac)) ((suc va) or (duc va)) nhan viec cua te".
• Adding a wildcard symbol may retrieve word variants: thu sac ky nang xa hoi. hieu ((ve cao) OR (ve cac)) ((suc va) or (duc va)) nhan viec cua te*.
