• If you are trying to use Boolean operators, they must be ALL CAPS: ((tang zheng) OR (wang yuhan)) jing ta ((china change) OR (china chang)) hong wang zhi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tang zheng) or (wang yuhan)) jing ta ((china change) OR (china chang)) hong wang zhi ;~".
• Adding a wildcard symbol may retrieve word variants: ((tang zheng) or (wang yuhan)) jing ta ((china change) OR (china chang)) hong wang zhi ;*.
