• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wang yang) OR (hong cheng))) OR (yang yang)) ((yang di) OR (yang yi)) xu yuan jie song siu ;~.
• Adding a wildcard symbol may retrieve word variants: ((((wang yang) or (hong cheng))) or (yang yang)) ((yang di) or (yang yi)) xu yuan jie song siu ;*.
