• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach kho tang xa hoi. hieu ((((ve cam) OR (va cam))) OR (ve cac)) tuc va danh vai cua tre~.
• Adding a wildcard symbol may retrieve word variants: tu sach kho tang xa hoi. hieu ((((ve cam) or (va cam))) or (ve cac)) tuc va danh vai cua tre*.
