• If you are trying to use Boolean operators, they must be ALL CAPS: ((te san) OR (ke dan)) ky nang xa hoi. hieu van nam thuc ((van hanh) OR (va danh)) dai cuu tre.
• Adding a wildcard symbol may retrieve word variants: ((te san) or (ke dan)) ky nang xa hoi. hieu van nam thuc ((van hanh) or (va danh)) dai cuu tre*.
