• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang liang) OR (wang yanling)) han china dan yang ((jin kang) OR (jin kyung)) hari ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang liang) or (wang yanling)) han china dan yang ((jin kang) OR (jin kyung)) hari ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang liang) or (wang yanling)) han china dan yang ((jin kang) OR (jin kyung)) hari ;*.
