• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yong) OR (((wang yang) OR (wang liang)))) yang hua gene yang minh hong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yong) or (((wang yang) OR (wang liang)))) yang hua gene yang minh hong shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yong) or (((wang yang) OR (wang liang)))) yang hua gene yang minh hong shu ;*.
