• If you are trying to use Boolean operators, they must be ALL CAPS: qian yang yang ((di zheng) OR (qin zheng)) ((cong zheng) OR (hong cheng)) song jin ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "qian yang yang ((di zheng) OR (qin zheng)) ((cong zheng) or (hong cheng)) song jin ;~".
• Adding a wildcard symbol may retrieve word variants: qian yang yang ((di zheng) OR (qin zheng)) ((cong zheng) or (hong cheng)) song jin ;*.
