• If you are trying to use Boolean operators, they must be ALL CAPS: dong zhang fan ta chen yan min ((((hong shu) OR (tong shui))) OR (gong hui)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong zhang fan ta chen yan min ((((hong shu) OR (tong shui))) or (gong hui)) ;~".
• Adding a wildcard symbol may retrieve word variants: dong zhang fan ta chen yan min ((((hong shu) OR (tong shui))) or (gong hui)) ;*.
