Perhaps you should try some spelling variations:
wei yang » pei yang, wei wang, wei yang's
yang yan » yang yang, wang yan, yang fan
gene set » gene sets, game set, gene we
note use » note de, note one
gene one » gene clone, gene gene, gene we
can only » can one
yan a » can a, yan _, jan a
raul » paul, rail, raum

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

• If you are trying to use Boolean operators, they must be ALL CAPS: wei yang yan a ((((gene set) OR (note use))) OR (gene one)) can only raul ;~.
• Adding a wildcard symbol may retrieve word variants: wei yang yan a ((((gene set) or (note use))) or (gene one)) can only raul ;*.
