Perhaps you should try some spelling variations:
genome can » genre can, genome scale, genomen bank
join song » jin song, john song, soin sont
a genome » _ genome, 7 genome, pan genome
can join » can job, a join
yan yan » yan yuan, yang yang, wang yan
nan yan » nan ya, wang yan, qian yan
wang » wing, wan, lang

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang ((yan yan) OR (nan yan)) a genome can join song (sar or star) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yan yan) OR (nan yan)) a genome can join song (sar OR star) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan yan) OR (nan yan)) a genome can join song (sar or star) ;*".
