Search results showing products and posts/pages

Hi

I have a search bar in the header and one search bar on the side menue in the shop. The results that I get are both products and pages/posts. How do I limit the search results only to products?
My search.php is
get_header();

?>

<div id=”content” class=”blog-wrapper blog-archive page-wrapper”>
<?php get_template_part( ‘template-parts/posts/layout’, get_theme_mod(‘blog_layout’,’right-sidebar’) ); ?>
</div><!– .page-wrapper .blog-wrapper –>

<?php get_footer(); ?>
