Perhaps you should try some spelling variations:
cua viet » hoa viet, cua vat, cua dieu
ca viet » va viet, co viet, hoa viet
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
hanh ca » hanh cac, hanh cat, hanh cua
su sac » su sach, su cac, su xac
tuc va » thuc va, truc va, tuc xa
sac ky » cac ky, sai ky
ve cam » ve cham, ve cac, va cam

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 xa hoi. hieu ve cam ((duc va) or (tuc va)) hanh ca ((cua viet) OR (ca viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky nang xa hoi. hieu ve cam ((duc va) OR (tuc va)) hanh ca ((cua viet) OR (ca viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky nang xa hoi. hieu ve cam ((duc va) or (tuc va)) hanh ca ((cua viet) OR (ca viet))".
• Adding a wildcard symbol may retrieve word variants: su sac ky nang xa hoi. hieu ve cam ((duc va) or (tuc va)) hanh ca ((cua viet) OR (ca viet))*.
