• If you are trying to use Boolean operators, they must be ALL CAPS: tu sai ky nang xa hoi. hieu ((((van cam) OR (van nam))) OR (van lam)) duc ban thanh tai cua tre.
• Adding a wildcard symbol may retrieve word variants: tu sai ky nang xa hoi. hieu ((((van cam) or (van nam))) or (van lam)) duc ban thanh tai cua tre*.
