So I managed to back up an entire wikipedia-like site. And it has a search
function on the main page. However, if I try to do a search it tries to fetch
the info online, and not locally. 

#1:  Is there be a simple way to change this?
I know next to nothing about building websites, but the best I can figure out
is that the search phrases end up in something called opensearch_desc.php
(which didn't get saved locally, for some reason).

#2: Would it be possible to change the HTTP stuff in HTML files so that
instead of pointing to (for example)
[i]http://thewiki.com/searchfunction.php[/i]
it would look for the locally saved search script
[i]C:\TheWiki\searchfunction.php ? [/i]

I know I could just use the Windows built-in search function but the search
input field is, like, *right there*.
