• The words AND, OR and NOT may confuse the search; try adding quotes: "yuan ting tan ((hua gene) or (((human gene) OR (human bone)))) ying jin wong shiu ;~".
• Adding a wildcard symbol may retrieve word variants: yuan ting tan ((hua gene) or (((human gene) OR (human bone)))) ying jin wong shiu ;*.
