• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang ma hoi. hieu qua cam ((((duc va) OR (truc va))) OR (loc va)) hanh tai cuu tre.
• Adding a wildcard symbol may retrieve word variants: te sach ky nang ma hoi. hieu qua cam ((((duc va) or (truc va))) or (loc va)) hanh tai cuu tre*.
