• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang xa hoi. hieu ((((ve cam) OR (va cac))) OR (ve cham)) duc va dan di va triet.
• Adding a wildcard symbol may retrieve word variants: te sach ky nang xa hoi. hieu ((((ve cam) or (va cac))) or (ve cham)) duc va dan di va triet*.
