• If you are trying to use Boolean operators, they must be ALL CAPS: ((((((dan yang) OR (yang yang))) OR (dong hoang))) OR (dong di)) ya huang cheng ling min hong ng ;~.
• Adding a wildcard symbol may retrieve word variants: ((((((dan yang) or (yang yang))) or (dong hoang))) or (dong di)) ya huang cheng ling min hong ng ;*.
