hieu va » lieu va, hieu qua
hanh di » hanh vi, hanh de, hang di
cuu tre » cua tre, cau tren, cau treo

• If you are trying to use Boolean operators, they must be ALL CAPS: tu lanh dao lang xa hoi. hieu va ((((chao xu) OR (cham soc))) OR (cam xuc)) van hanh di cuu tre.
• Adding a wildcard symbol may retrieve word variants: tu lanh dao lang xa hoi. hieu va ((((chao xu) or (cham soc))) or (cam xuc)) van hanh di cuu tre*.
