• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong hoang) OR (wang yan)) ((((yang jui) OR (fung chung))) OR (yang xi)) seen yan wang yong yu ;~.
• Adding a wildcard symbol may retrieve word variants: ((dong hoang) or (wang yan)) ((((yang jui) or (fung chung))) or (yang xi)) seen yan wang yong yu ;*.
