• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky ((lang xa) OR (lang ha)) hoi. hieu ((va cam) OR (va cac)) duc va danh sai cua tre.
• Adding a wildcard symbol may retrieve word variants: tu sach ky ((lang xa) or (lang ha)) hoi. hieu ((va cam) or (va cac)) duc va danh sai cua tre*.
