• If you are trying to use Boolean operators, they must be ALL CAPS: yang ((yue wang) OR (huang cheng)) ((hua rene) OR (hua ren)) yang jin song min ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang ((yue wang) or (huang cheng)) ((hua rene) OR (hua ren)) yang jin song min ;~".
• Adding a wildcard symbol may retrieve word variants: yang ((yue wang) or (huang cheng)) ((hua rene) OR (hua ren)) yang jin song min ;*.
