sach ky » sac ky, sach ty, sach kem
nang xa » nang x, lang xa, nang ma
hanh va » hang va, hanh vi
cuu tre » cua tre, cau tren, cau treo
va cau » van cau, va cac, va dau

• Performing a fuzzy search may retrieve terms with similar spellings: tu ((((sach ky) or (cac ky))) or (sach y)) nang xa hoi. lieu va cau thuc vat hanh va cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((((sach ky) OR (cac ky))) OR (sach y)) nang xa hoi. lieu va cau thuc vat hanh va cuu tre.
• Adding a wildcard symbol may retrieve word variants: tu ((((sach ky) or (cac ky))) or (sach y)) nang xa hoi. lieu va cau thuc vat hanh va cuu tre*.
