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