search form not working properly

I’ve got a search form in the main nav of a site I’m building. For some reason, it’s not fully working. The search will only work if you try to pull up an exact page title. If you search for a name or a term on a page, it does not turn up any results. For example, there is a person named Beth listed on the About page, but when you search “Beth” in the search bar, it does not pull up any results.

What could be the issue?

Here’s a link to my test site: http://test.cgla.net/. It’s got a password on it, just so the client can’t see it yet. It’s Cabrini2017!

Here’s the code from header.php for the search form:

<div class="search-dropdown" style="display: block;">
            <form method="get" id="searchform" action="<?php echo site_url(); ?>">
	<input type="text" class="field" name="s" id="s" placeholder="What are you looking for?">
	<button type="submit" class="submit" name="submit" id="searchsubmit"><i class="fa fa-search fa-lg"></i></button>
</form>        
</div>

Here’s the jQuery I’m using for the hide&show feature:

 /*Hide&Show search bar in header*/

       $(document).ready(function(){
         $("#searchform").hide();
    $(".search-trigger").click(function(){
        $("#searchform").fadeToggle(200);
    });
});
