WordPress Custom Layout in Search Result Page with Bootstrap

I would like some help if possible in the following question:

I use in my Genesis theme a bootstrap grid, and would like to display the search results using this grid.

I created a search.php with the following code:

<?php
/**
 * Search Results Template File
 */ 
get_header(); ?>
    <header>
        <h1>Search Results: &quot;<?php echo get_search_query(); ?>&quot;</h1>
        <br>
    </header>

<?php if ( have_posts() ) :  // results found?>
    <?php while ( have_posts() ) : the_post(); ?>

<div class="container-fluid">

<div class="row">

<div class="col-md-3 col-sm-6 col-xs-12">
<div class="gr-infos-container-cliente">
<div class="gr-promo-do-cliente"><?php the_field('tipo_de_promo');?></div>
<div class="gr-img-cliente"><a href="<?php the_permalink();?>" title="<?php the_title();?>"><img src="<?php echo get_field('foto_cliente_miniatura');?>" alt="" class="img-responsive center-block"></a></div>
<div class="gr-nome-cliente"><a href="<?php the_permalink();?>" title="<?php the_title();?>"><?php the_title();?></a></div>
<div class="gr-tagline-cliente"><?php the_field('tagline_do_anunciante');?></div>
<div class="gr-bairro-do-cliente"><i class="cliente fa fa-map-marker"></i><?php the_field('bairro_do_cliente');?></div>
</div>
</div>

</div> <!-- Row -->

</div> <!-- Container -->

<?php endwhile; ?>

<?php else :  // no results?>
    <article>
        <h1>No Results Found.</h1>
    </article>
<?php endif; ?>
<?php get_footer(); ?>

genesis();

But in the search result, the content is aligned one on top of another and not in the selected grid.

Any tips you can give me?

I am very grateful for any help!
