• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty dang ((((cay phoi) OR (cay cho))) OR (cap cho)). hieu va bao duc van nang phai cua tre~.
• Adding a wildcard symbol may retrieve word variants: su sach ty dang ((((cay phoi) or (cay cho))) or (cap cho)). hieu va bao duc van nang phai cua tre*.
