• If you are trying to use Boolean operators, they must be ALL CAPS: han chang yang zili ((((gene long) OR (gene one))) OR (gene gene)) thanh jan paul ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "han chang yang zili ((((gene long) OR (gene one))) or (gene gene)) thanh jan paul ;*".
