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