Perhaps you should try some spelling variations:
now small » how small, new small, now shall
yang jan » yang fan, yang jun, yang dean
yang jui » yang judy, yang di, yang xi
yang jin » yang jie, yang jun, ying jin
gene let » gene set, gene sets, gene we
gene one » gene clone, gene gene, gene we
them now » them know, them how, them newt

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: wang ((((yang jan) OR (yang jui))) OR (yang jin)) a ((gene let) OR (gene one)) them now small ;~.
• Adding a wildcard symbol may retrieve word variants: wang ((((yang jan) or (yang jui))) or (yang jin)) a ((gene let) or (gene one)) them now small ;*.
