• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR wan) yanling yang hua gene yang lin ((hong g) OR (((hong hai) OR (hong ghi)))) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wan) yanling yang hua gene yang lin ((hong g) or (((hong hai) OR (hong ghi)))) ;".
