• If you are trying to use Boolean operators, they must be ALL CAPS: gong ((gang sung) OR (gang und)) zhi ((jiang yajing) OR (jiang liping)) minh wong shiu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "gong ((gang sung) OR (gang und)) zhi ((jiang yajing) or (jiang liping)) minh wong shiu ;".
• Adding a wildcard symbol may retrieve word variants: gong ((gang sung) OR (gang und)) zhi ((jiang yajing) or (jiang liping)) minh wong shiu ;*.
