looks like the code is this:
<h1>Search and Results</h1>
<form id="BingSearchForm" name="BingSearchForm" method="get" action="" onsubmit="processBingQuery('put your api code here', 'put your domain here', 10); return false;">
<label for="Bing_query">Search for: </label>
<input type="text" name="Bing_query" id="Bing_query" value="">
<input type="submit" name="button" id="button" value="Search">
</form>
<div id="BingResults"></div>
