Perhaps you should try some spelling variations:
cau thuc » cau truc, cuu thuc, can thuc
diem cau » dieu can
hieu van » hieu va, thien van, lieu va
va dinh » van dinh, va kinh, va tinh
thuc va » thuc vat, thuc dan, thuc day
van cau » van dau, van hau, van chat
sac ky » cac ky, sai ky
di cuu » di cua, dinh cuu
di cau » da cau
vu sac » vu sach, vu san, va sac
x hoi » xa hoi, o hoi, x ho

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

• If you are trying to use Boolean operators, they must be ALL CAPS: vu sac ky nang x hoi. hieu van cau thuc va dinh ((di cuu) OR (((di cau) OR (diem cau)))) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sac ky nang x hoi. hieu van cau thuc va dinh ((di cuu) or (((di cau) OR (diem cau)))) tre~".
• Adding a wildcard symbol may retrieve word variants: vu sac ky nang x hoi. hieu van cau thuc va dinh ((di cuu) or (((di cau) OR (diem cau)))) tre*.
