• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang yi) OR (yang fan))ng ya human gene tang min ((((jeong mi) OR (jong min))) OR (jeongui 情)) ;~.
• Adding a wildcard symbol may retrieve word variants: ((yang yi) or (yang fan))ng ya human gene tang min ((((jeong mi) or (jong min))) or (jeongui 情)) ;*.
