I found that [Asad Manzoors][1] answer worked for me. If anyone needs it, my version required `paged` be implented:

```
$search_query = trim(esc_html( get_search_query() ));
$posts_per_page = $wp_query->query_vars['posts_per_page'];
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;

$q1 = new WP_Query(array(
	's' => $search_query,
	'post_type' => array('page', 'post'),
	'posts_per_page' => -1,
	'fields' => 'ids'
));
$q2 = new WP_Query(array(
	'fields' => 'ids',
	'post_type' => array('page', 'post'),
	'posts_per_page' => -1,
	'meta_query' => array(
		'relation' => 'AND',
		array(
			'key' => 'custom_body',
			'value' => $search_query,
			'compare' => 'LIKE'
		)
	)
));

$unique = array_unique(array_merge($q1->posts, $q2->posts));

// If no posts found, ensure that the $query doesn't select every post.
if (!$unique) {
	$unique = array(-1);
}

$query = new WP_Query(array(
	'post_type' => array('page', 'post'),
	'post__in' => $unique,
	'paged' => $paged,
	'post_status' => 'publish',
	'posts_per_page' => $posts_per_page
));	
```
