• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yangming's) OR (boon chong)) ((yang jui) OR (yang yang)) yi dong hoang kong siu ;~.
• Adding a wildcard symbol may retrieve word variants: ((wang yangming's) or (boon chong)) ((yang jui) or (yang yang)) yi dong hoang kong siu ;*.
