• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky nang van hoi. hieu va ((((cam duc) OR (pham duc))) OR (cam xuc)) ban thanh dai cua tre.
• Adding a wildcard symbol may retrieve word variants: su sac ky nang van hoi. hieu va ((((cam duc) or (pham duc))) or (cam xuc)) ban thanh dai cua tre*.
