How to change search results based in content and not just titles?

Got it

<?php
/**
 * Search Template
 *
 * The template for displaying Search Results pages.
 */

get_header(); ?>

<div id="main"><div class="wrap cf">

	<div id="content" role="main">

	<?php get_template_part('loop-header'); ?>

		<?php if (have_posts()) : global $loop_view; ?>

			<?php get_template_part('loop-actions'); ?>

			<div class="loop-content switchable-view <?php echo $loop_view; ?>" data-view="<?php echo $loop_view; ?>">
				<div class="nag cf">
					<?php while (have_posts()) : the_post();
						get_template_part('item-video');
					endwhile; ?>
				</div>
			</div><!-- end .loop-content -->

			<?php get_template_part('loop-nav'); ?>

		<?php else : ?>

			<?php get_template_part('loop-error'); ?>

		<?php endif; ?>

	</div><!-- end #content -->

	<?php get_sidebar(); ?>

</div></div><!-- end #main -->

<?php get_footer(); ?>

This is item-video.php

<?php
/**
 * The template for displaying videos in section box or on archive pages
 *
 * @package deTube
 * @subpackage Template
 * @since deTube 1.0
 */
?>
	<div id="post-<?php the_ID(); ?>" <?php $item_format = is_video() ? 'video' : 'post'; post_class('item cf item-'.$item_format); ?>>
		<?php
			// Set image size based on section view, only for section box
			global $section_view;
			$thumb_size = 'custom-large';
			if(!empty($check_view)) {
				if($check_view == 'list-large')
					$thumb_size = 'custom-large';
				elseif($check_view == 'grid-mini')
					$thumb_size = 'custom-small';
			}
			dp_thumb_html($thumb_size);
		?>

		<div class="data">
			<h2 class="title"><a href="<?php the_permalink(); ?>" rel="bookmark" title="<?php printf(__('Permalink to %s', 'dp'), get_the_title()); ?>"><?php the_title(); ?></a></h2>

			<p class="meta">
				<span class="author"><?php _e('Added by', 'dp'); ?> <?php the_author_posts_link(); ?></span>
				<span class="time"><?php printf(__('%s ago', 'dp'), human_time(get_the_time('U'))); ?></span>
			</p>

			<p class="stats"><?php echo dp_get_post_stats(); ?></p>

			<p class="desc"><?php dp_excerpt(); ?></p>
		</div>
	</div><!-- end #post-<?php the_ID(); ?> -->

And this is

Loop-actions.php

<?php
/**

 *
 * The template displays the loop actions on archive pages.
 *
 * @package deTube
 * @subpackage Template
 * @since deTube 1.0
