• If you are trying to use Boolean operators, they must be ALL CAPS: tu can ky nang xa hoi. hieu ve cam tu va hanh ((((hai cua) OR (dai cua))) OR (hoi cua)) tre.
• Adding a wildcard symbol may retrieve word variants: tu can ky nang xa hoi. hieu ve cam tu va hanh ((((hai cua) or (dai cua))) or (hoi cua)) tre*.
