Perhaps you should try some spelling variations:
viec khoa » vien khoa, viec khong, lieu khoa
cau treo » cau theo, cau tren, cau triet
viec cho » viec nhom, viec cua, viec so
nang xa » nang x, lang xa, nang ma
vu sach » vu bach, vu khach
xuc cam » phuc cam
cam dan » cac dan, ca dan, nam dan
su sach » so sach
dan va » doan va, dan ca, ban va
va cau » van cau, va cac, va dau

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) OR (vu sach)) ky nang xa hoi. hieu ((viec cho) or (viec khoa)) xuc cam dan va cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) ky nang xa hoi. hieu ((viec cho) OR (viec khoa)) xuc cam dan va cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (vu sach)) ky nang xa hoi. hieu ((viec cho) or (viec khoa)) xuc cam dan va cau treo".
• Adding a wildcard symbol may retrieve word variants: ((su sach) OR (vu sach)) ky nang xa hoi. hieu ((viec cho) or (viec khoa)) xuc cam dan va cau treo*.
