• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yang) OR (dong di)) ((((ya chuan) OR (ya hua))) OR (tai chun)) bang yan change among hai ;~.
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (dong di)) ((((ya chuan) or (ya hua))) or (tai chun)) bang yan change among hai ;*.
