• The words AND, OR and NOT may confuse the search; try adding quotes: "wang denen ((yang li) or (((wang lei) or (wang wei)))) gene we kong ((heng hai) OR (cheng han)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang denen ((yang li) or (((wang lei) or (wang wei)))) gene we kong ((heng hai) OR (cheng han)) ;*.
