• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty nang xa hoi. thien van bao duc ((((va thanh) OR (le thanh))) OR (va tinh)) hoi cua tre.
• Adding a wildcard symbol may retrieve word variants: su sach ty nang xa hoi. thien van bao duc ((((va thanh) or (le thanh))) or (va tinh)) hoi cua tre*.
