• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach y nang xa hoi. hieu ((((ve cai) OR (te tai))) OR (va cham)) tuc va hanh di cua tu.
• Adding a wildcard symbol may retrieve word variants: thu sach y nang xa hoi. hieu ((((ve cai) or (te tai))) or (va cham)) tuc va hanh di cua tu*.
