• If you are trying to use Boolean operators, they must be ALL CAPS: lang liang tan chia wen ((((yang jun) OR (yang jui))) OR (yang xi)) ((wong sau) OR (kong sara)) ;~.
• Adding a wildcard symbol may retrieve word variants: lang liang tan chia wen ((((yang jun) or (yang jui))) or (yang xi)) ((wong sau) or (kong sara)) ;*.
