• If you are trying to use Boolean operators, they must be ALL CAPS: wang yan yang ((li li) OR (li lu)) ((gong min) OR (song min)) ((congo shu) OR (song shin)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang yan yang ((li li) or (li lu)) ((gong min) or (song min)) ((congo shu) or (song shin)) ;*.
