• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang x hoi. hieu va cham soc van hanh vi ((((cua tre) OR (dung tren))) OR (cua te)).
• Adding a wildcard symbol may retrieve word variants: te sach ky nang x hoi. hieu va cham soc van hanh vi ((((cua tre) or (dung tren))) or (cua te))*.
