• If you are trying to use Boolean operators, they must be ALL CAPS: te ((((sach ty) OR (sach tham))) OR (sach tu)) dang van hoi. hieu va cam thuc vat hang di cuu tre~.
• Adding a wildcard symbol may retrieve word variants: te ((((sach ty) or (sach tham))) or (sach tu)) dang van hoi. hieu va cam thuc vat hang di cuu tre*.
