Vim search under cursor

[jm.suresh@no.spam.gmail.com]

Hi, I am using gvim to edit python source files. When I press "*" or
"#", I would want to search for the attribute name under the cursor
and not the entire string.
 For example, If I have os.error and pressing * on top of error
searches for os.error rather than error. How to set this, any Idea?

thanks.
