• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang ma hoi. hieu va ((((giao duc) OR (cao suc))) OR (tao duoc)) va dan lai cua tre.
• Adding a wildcard symbol may retrieve word variants: te sach y nang ma hoi. hieu va ((((giao duc) or (cao suc))) or (tao duoc)) va dan lai cua tre*.
