• The words AND, OR and NOT may confuse the search; try adding quotes: "wang wang liang jin rent ((chang min) OR (zhang ming)) ((hong ghi) or (hong seo)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang wang liang jin rent ((chang min) OR (zhang ming)) ((hong ghi) or (hong seo)) ;*.
