How do you zoom to a search result?

[Jason Domina]

What type of approach do I need to take to get this type of feature?
Specifically, I want to know how to implement a search feature like the one in
the gallery site:

Even just a clue would help this clueless cowboy.  Also, if there isn't a faq
I'd volunteer to help create and maintain one.  If there is a faq, Where?

Thank you,
Jason
