Perhaps you should try some spelling variations:
more small » korea small, some small, one small
them more » them work
yang jan » yang jun, yang dean, yang yang
yang fan » zhang fan, yang dean, yang yang
yang jin » yang jie, yang jun, ying jin
gene fit » gene set
gene i » gene _, gene m, gene 1

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang ((((yang jan) OR (yang fan))) or (yang jin)) a ((gene fit) or (gene i)) them more small ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((((yang jan) OR (yang fan))) OR (yang jin)) a ((gene fit) OR (gene i)) them more small ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((yang jan) OR (yang fan))) or (yang jin)) a ((gene fit) or (gene i)) them more small ;".
• Adding a wildcard symbol may retrieve word variants: wang ((((yang jan) OR (yang fan))) or (yang jin)) a ((gene fit) or (gene i)) them more small ;*.
