Search function addition, please help

[crippe]

I thought it would be cool to add a search function into each category, in this case "Michael",  let me explain......

While inside a category "Michael" you might have, let say, 4 albums........

Your bredcrumbs looks like this

Home > Friends > Michael

Now, what would be cool is, if you could add a link that says "Click here to search for all categories containg the keyword Michael"

Is it possible to take some data from the bredcrumbs and hardcode it with the search function and then create a link on each page? If someone have any idea how to do this, could you point me in the right direction or tell me how to do it? 

Please help
