• If you are trying to use Boolean operators, they must be ALL CAPS: ((qian wang) OR (hoong chang)) yang die ((schone chang) OR (school change)) xin hong seo ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((qian wang) or (hoong chang)) yang die ((schone chang) OR (school change)) xin hong seo ;~".
• Adding a wildcard symbol may retrieve word variants: ((qian wang) or (hoong chang)) yang die ((schone chang) OR (school change)) xin hong seo ;*.
