• If you are trying to use Boolean operators, they must be ALL CAPS: ((qian yan) OR (yuan chang)) liang li ((gene long) OR (gene clone)) thanh hong sau ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((qian yan) or (yuan chang)) liang li ((gene long) OR (gene clone)) thanh hong sau ;*".
