• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ryan lanka p.w les zhang making ((using seng) or (((hong sheng) OR (fang sheng)))) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ryan lanka p.w les zhang making ((using seng) or (((hong sheng) OR (fang sheng)))) ;*.
