• If you are trying to use Boolean operators, they must be ALL CAPS: wang liang ((((tan zhi) OR (wang zhi))) OR (yan zhi)) lee ann ((min zhong) OR (min hong)) zhi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang liang ((((tan zhi) OR (wang zhi))) or (yan zhi)) lee ann ((min zhong) or (min hong)) zhi ;~".
• Adding a wildcard symbol may retrieve word variants: wang liang ((((tan zhi) OR (wang zhi))) or (yan zhi)) lee ann ((min zhong) or (min hong)) zhi ;*.
