• If you are trying to use Boolean operators, they must be ALL CAPS: te sai ky ((((nang xa) OR (nang x))) OR (lang ha)) hoi. hieu va cam luc van hanh vi cuu tre.
• Adding a wildcard symbol may retrieve word variants: te sai ky ((((nang xa) or (nang x))) or (lang ha)) hoi. hieu va cam luc van hanh vi cuu tre*.
