• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc ((sach thue) OR (sach thieu)) hang xa hoi. hieu van dau thuc vat thanh do cua tre~.
• Adding a wildcard symbol may retrieve word variants: thuoc ((sach thue) or (sach thieu)) hang xa hoi. hieu van dau thuc vat thanh do cua tre*.
