Searching client side

At the moment in my office we gotta move a site from one server to another. It will stay on this server temporarily because we got a new one ordered but we don’t expect it for about 8 weeks. Anyway the site uses a database just now but once we move it, it won’t be able to. It will on the new server but not on it’s temporary home.

We’re obviously gonna lose some functionality as the site becomes static but I was wondering about the search. Does anyone know of a client side search facility?
