• If you are trying to use Boolean operators, they must be ALL CAPS: yuan wang ((((tan hua) OR (tuan hua))) OR (qian juan)) (ren OR rent) yan min hong yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yuan wang ((((tan hua) OR (tuan hua))) or (qian juan)) (ren or rent) yan min hong yu ;~".
• Adding a wildcard symbol may retrieve word variants: yuan wang ((((tan hua) OR (tuan hua))) or (qian juan)) (ren or rent) yan min hong yu ;*.
