• If you are trying to use Boolean operators, they must be ALL CAPS: ((((lang yan) OR (yang jui))) OR (((yang xi) OR (yang di))))peg a n chen shuang yin hang c ;~.
• Adding a wildcard symbol may retrieve word variants: ((((lang yan) or (yang jui))) or (((yang xi) or (yang di))))peg a n chen shuang yin hang c ;*.
