• If you are trying to use Boolean operators, they must be ALL CAPS: zhang zhang hans von welt ((((liang ying) OR (jiang yajing))) OR (huang ying)) kong sar ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "zhang zhang hans von welt ((((liang ying) OR (jiang yajing))) or (huang ying)) kong sar ;~".
• Adding a wildcard symbol may retrieve word variants: zhang zhang hans von welt ((((liang ying) OR (jiang yajing))) or (huang ying)) kong sar ;*.
