Perhaps you should try some spelling variations:
thien van » thi van
hanh dinh » thanh dinh, hinh dinh, hanh tinh
dang tay » dang xay, dan tay, bang tay
dung tay » dung tai, dung may, vung tay
van cac » van hac, van cau, van bac
dinh cu » dinh cuu, dinh chuc, dinh chau
te sach » toc sach
sach ky » sac ky, sach y, sach ty
xuc va » duc va, tuc va, luc va
cu tre » cu tren, cua tre, cuu tre

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky ((dang tay) OR (dung tay)) hoi. thien van cac ((xuc va) or (thuc vat)) hanh dinh cu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((dang tay) OR (dung tay)) hoi. thien van cac ((xuc va) OR (thuc vat)) hanh dinh cu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((dang tay) OR (dung tay)) hoi. thien van cac ((xuc va) or (thuc vat)) hanh dinh cu tre".
• Adding a wildcard symbol may retrieve word variants: te sach ky ((dang tay) OR (dung tay)) hoi. thien van cac ((xuc va) or (thuc vat)) hanh dinh cu tre*.
