Perhaps you should try some spelling variations:
quan cau » quang cao, toan cau, quan ha
cau treo » cau theo, cau tren, cau triet
qua cau » qua cac, qua ca, qua cai
truc va » thuc va, thuc vat, trung va
hanh va » hang va
su sac » su sach, su cac, su xac
sac ky » cac ky, sai ky
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sac ky nang x hoi. hieu ((qua cau) or (quan cau)) truc va ((hanh va) OR (hanh vi)) cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky nang x hoi. hieu ((qua cau) OR (quan cau)) truc va ((hanh va) OR (hanh vi)) cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky nang x hoi. hieu ((qua cau) or (quan cau)) truc va ((hanh va) OR (hanh vi)) cau treo".
• Adding a wildcard symbol may retrieve word variants: su sac ky nang x hoi. hieu ((qua cau) or (quan cau)) truc va ((hanh va) OR (hanh vi)) cau treo*.
