• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (hoc sach)) ky hoang van hoc. hieu ve coc ((thuc va) OR (thuc vat)) tinh voi cua tre~.
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (hoc sach)) ky hoang van hoc. hieu ve coc ((thuc va) or (thuc vat)) tinh voi cua tre*.
