make textbox work like dropdown box
<p>I am trying to replicate the functionality I have on a dropdown box that allows a user to select a tag and then return articles related to this term,.</p>

<p>The textbox needs to accept a search term and work in the same way. I have tried everything I can think of but I am getting zero results.</p>

<p>To replicate the behavior, select an item from the dropdown box and it will return articles. Then try typing the same term in the search box and it returns no articles.</p>

<p>Any idea why? Here's the site:</p>
