How I can filter the Opportunity search result?

Hi experts,

I want to filter the oppotunity search result,

is there anybody knows the BADI/METHOD name in which I can do this.

My scenario is:

In web ui,go to Sales cycle,opportunity search,

when I click the button "Search",

I want to filter the result list,only the login user itself who created oppotunities should be listed.

How should I do?

Thanks

Jerry
