van hoi » van hoa, van hoc, van hoe
hieu tu » chieu tu, hieu tuc, hien tu
tu cham » toc cham, thi cham
cua tre » cua te, cuu tre, cua triet

• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky tang van hoi. hieu tu cham ((so ban) OR (hoc dan)) hanh vi cua tre~.
• Adding a wildcard symbol may retrieve word variants: tu cac ky tang van hoi. hieu tu cham ((so ban) or (hoc dan)) hanh vi cua tre*.
