• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR lang) xiaotong zhang ((chun tan) OR (((chen tan) OR (chen jian)))) eng hong hong than ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or lang) xiaotong zhang ((chun tan) or (((chen tan) OR (chen jian)))) eng hong hong than ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or lang) xiaotong zhang ((chun tan) or (((chen tan) OR (chen jian)))) eng hong hong than ;*.
