It’s very simple standard search.php – i’m fairly certain it isn’t templating related but have a look – it’s built off of Bones WP :
<?php get_header('search'); ?>
<div id="content">
<div id="inner-content" class="wrap cf">
<main id="main" class="cf" role="main" itemscope itemprop="mainContentOfPage" itemtype="http://schema.org/Blog">
<!-- USER PANELS -->
<article class="cf" role="article" itemscope itemtype="http://schema.org/BlogPosting">
<section class="middlecontent cf" itemprop="articleBody">
<h3>Results:</h3>
<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<?php
$posts = get_field('author_selector');
if( $posts ): ?>
<?php foreach( $posts as $post): // variable must be called $post (IMPORTANT) ?>
<?php setup_postdata($post); ?>
<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
<?php endforeach; ?>
<?php wp_reset_postdata(); // IMPORTANT - reset the $post object so the rest of the page works correctly ?>
<?php endif; ?>
<figure class="effect-marley m-all t-1of3 d-1of3">
<div class="thumbwrap">
<?php if ( get_the_post_thumbnail($post_id) != '' ) {
echo '<a href="'; the_permalink(); echo '" class="thumbnail-wrapper">';
the_post_thumbnail('sterling-largethumb');
echo '</a>';
} else {
echo '<a href="'; the_permalink(); echo '" class="thumbnail-wrapper">';
echo '<div class="fillthumb" style="background-image:url(';
echo catch_that_image();
echo ');"></div>';
echo '</a>';
} ?>
</div>
<figcaption>
<h2><?php the_title(); ?></h2>
<p><?php the_excerpt(); ?></p>
<a href="<?php the_permalink(); ?>">View more</a>
</figcaption>
</figure>
<?php endwhile; ?>
<?php wpex_pagination(); ?>
<?php else : ?>
<?php endif; ?>
</section>
</article>
</main>
</div>
</div>
<?php get_template_part( 'partials/socialmedia', '' ); ?>
<?php get_footer(); ?>
