• If you are trying to use Boolean operators, they must be ALL CAPS: wang tang liu yuan yi ((gang yi) OR (tang yi)) ((fang zheng) OR (fang zhen)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang tang liu yuan yi ((gang yi) or (tang yi)) ((fang zheng) OR (fang zhen)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang tang liu yuan yi ((gang yi) or (tang yi)) ((fang zheng) OR (fang zhen)) ;*.
