• If you are trying to use Boolean operators, they must be ALL CAPS: zhang ying ((tan chen) OR (tan cheng)) tan ying huang ((cheng mae) OR (chang mae)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "zhang ying ((tan chen) or (tan cheng)) tan ying huang ((cheng mae) OR (chang mae)) ;~".
• Adding a wildcard symbol may retrieve word variants: zhang ying ((tan chen) or (tan cheng)) tan ying huang ((cheng mae) OR (chang mae)) ;*.
