• If you are trying to use Boolean operators, they must be ALL CAPS: ((((zhang zhang) OR (cheng zhang))) OR (wang zheng)) ping lin best die bank bond sales ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((zhang zhang) OR (cheng zhang))) or (wang zheng)) ping lin best die bank bond sales ;~".
• Adding a wildcard symbol may retrieve word variants: ((((zhang zhang) OR (cheng zhang))) or (wang zheng)) ping lin best die bank bond sales ;*.
