Perhaps you should try some spelling variations:
gene one » gene clone, gene gene, none one
yan jan » chan jan, yan clan, yan guan
gene we » gene set
tan one » than one, can one, tan hong
man one » many one, can one, than one
gene w » gene _, gene m, gene 1
jan a » jane a, can a, jan m
wang » wing, wan

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 OR lang) yan jan a ((((gene we) OR (gene one))) OR (gene w)) ((tan one) OR (man one)) saul ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or lang) yan jan a ((((gene we) OR (gene one))) or (gene w)) ((tan one) or (man one)) saul ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or lang) yan jan a ((((gene we) OR (gene one))) or (gene w)) ((tan one) or (man one)) saul ;*.
