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