• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wan yan) OR (wang yang))) OR (wai yan)) ((dean hua) OR (tan hua)) jia zhang kim song von ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wan yan) OR (wang yang))) or (wai yan)) ((dean hua) or (tan hua)) jia zhang kim song von ;~".
• Adding a wildcard symbol may retrieve word variants: ((((wan yan) OR (wang yang))) or (wai yan)) ((dean hua) or (tan hua)) jia zhang kim song von ;*.
