• If you are trying to use Boolean operators, they must be ALL CAPS: ((wan qiao) OR (wang qiao)) ((((yuan i) OR (yuan li))) OR (yuan zi)) china zhang wai chung shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan qiao) or (wang qiao)) ((((yuan i) OR (yuan li))) or (yuan zi)) china zhang wai chung shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((wan qiao) or (wang qiao)) ((((yuan i) OR (yuan li))) or (yuan zi)) china zhang wai chung shu ;*.
