• If you are trying to use Boolean operators, they must be ALL CAPS: yuan wang tao hua ren ((((sang minh) OR (anh minh))) OR (zhang ming)) ((hong shu) OR (hong yu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yuan wang tao hua ren ((((sang minh) or (anh minh))) or (zhang ming)) ((hong shu) OR (hong yu)) ;~".
• Adding a wildcard symbol may retrieve word variants: yuan wang tao hua ren ((((sang minh) or (anh minh))) or (zhang ming)) ((hong shu) OR (hong yu)) ;*.
