• If you are trying to use Boolean operators, they must be ALL CAPS: lang yan xi ((((hua chen) OR (a chen))) OR (human gene)) ((yang min) OR (ying jin)) hong hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan xi ((((hua chen) OR (a chen))) or (human gene)) ((yang min) or (ying jin)) hong hai ;*".
