Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
xuc ban » duc ban, cuc ban, quoc ban
ban anh » ban hanh, ban banh, ban danh
anh dan » anh dang, anh danh, canh dan
cua tre » cua te, cuu tre, dua tren
sac ky » cac ky, sai ky
va cam » va cham, va cac, va cao

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

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