• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((((yan wang) OR (yang yang))) OR (qian wang)) ((hua rain) OR (hua ban)) yang jin congo shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((yan wang) OR (yang yang))) or (qian wang)) ((hua rain) or (hua ban)) yang jin congo shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((((yan wang) OR (yang yang))) or (qian wang)) ((hua rain) or (hua ban)) yang jin congo shu ;*.
