Perhaps you should try some spelling variations:
gene closer » gene clone, gene clusters
closer than » lower than, closed chain
weng fang » jing fang, wen wang
than hong » tan hong, thang long, than one
hong than » hong tan, long thanh, hong hai
ming hua » ying hua, ming hung, ming lu
yang » lang

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: weng fang ((((ming hua) OR (wang hua))) or (yang di)) gene closer than hong than ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: weng fang ((((ming hua) OR (wang hua))) OR (yang di)) gene closer than hong than ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "weng fang ((((ming hua) OR (wang hua))) or (yang di)) gene closer than hong than ;*".
