Perhaps you should try some spelling variations:
thanh vi » thanh va, thanh ve, nhanh vi
luu truc » luu tru, cau truc, cuu thuc
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
va cham » va chat, va tham
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
xac va » tac va, ac va, bac va

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 nang xa hoi. hieu va cham ((xac va) or (duc va)) ((thanh vi) OR (hanh vi)) luu truc~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang xa hoi. hieu va cham ((xac va) OR (duc va)) ((thanh vi) OR (hanh vi)) luu truc.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. hieu va cham ((xac va) or (duc va)) ((thanh vi) OR (hanh vi)) luu truc".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. hieu va cham ((xac va) or (duc va)) ((thanh vi) OR (hanh vi)) luu truc*.
