I think there may be help at Wikipedia.org for this, but suspect there will be a fair amount of work to turn it into html.
A bit of googling found this:
(It will embed a wiki search into a webpage)
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head>
<title>Untitled Page</title>
</head>
<body>
<form action="search-redirect.aspx" id="searchform"><div>
<input id="searchInput" name="search" type="text" />
<input type='submit' name="go" class="searchButton" id="searchGoButton" value="Search" />
</div></form>
</body>
</html>
search-redirect.aspx [code behind]
----------------------------
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
public partial class search_redirect : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Response.Redirect("http://en.wikipedia.org/wiki/Special:Search?search="+Request.Params["search"]+"&go=Go");
}
}
Hope it helps.
