• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach y nang ((x hoi) OR (x ho)). hieu ve cam xuc va hanh dao ((cua tre) OR (cua tu)).
• Adding a wildcard symbol may retrieve word variants: thu sach y nang ((x hoi) or (x ho)). hieu ve cam xuc va hanh dao ((cua tre) or (cua tu))*.
