• If you are trying to use Boolean operators, they must be ALL CAPS: ping wang tan hua ((((chin chang) OR (china chang))) OR (colin chang)) kong heng yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ping wang tan hua ((((chin chang) OR (china chang))) or (colin chang)) kong heng yu ;~".
• Adding a wildcard symbol may retrieve word variants: ping wang tan hua ((((chin chang) OR (china chang))) or (colin chang)) kong heng yu ;*.
