• If you are trying to use Boolean operators, they must be ALL CAPS: wang liang jing fang ((((cheng ling) OR (cheng ming))) OR (chen wang)) john wong siu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang liang jing fang ((((cheng ling) OR (cheng ming))) or (chen wang)) john wong siu ;~".
• Adding a wildcard symbol may retrieve word variants: wang liang jing fang ((((cheng ling) OR (cheng ming))) or (chen wang)) john wong siu ;*.
