• If you are trying to use Boolean operators, they must be ALL CAPS: wang hong gang ((lof gene) OR (((1 gene) OR (11 gene)))) right cheng zhang wei ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang hong gang ((lof gene) or (((1 gene) OR (11 gene)))) right cheng zhang wei ;~".
• Adding a wildcard symbol may retrieve word variants: wang hong gang ((lof gene) or (((1 gene) OR (11 gene)))) right cheng zhang wei ;*.
