• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (hoc sach)) thu sang cho hoc. hieu ve ((cac luc) OR (cap nuoc)) ban hanh vi cua cau~.
• Adding a wildcard symbol may retrieve word variants: ((te sach) or (hoc sach)) thu sang cho hoc. hieu ve ((cac luc) or (cap nuoc)) ban hanh vi cua cau*.
