• If you are trying to use Boolean operators, they must be ALL CAPS: done using dna hua gene yan than ((((hong hai) OR (shang hai))) OR (hong than)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "done using dna hua gene yan than ((((hong hai) OR (shang hai))) or (hong than)) ;*".
