// Just add the snippet in your themes functions.php. You can use this shortcode in a post or page, as shown in the following example:

// [find_shortcode name='et_pb_dfbm_blog']

add_shortcode( 'find_shortcode', function( $atts, $content = false )

	[

	    's'              => esc_attr( $atts['name'] ),
	    'post_type'      => [ 'post', 'page' ],
	    'posts_per_page' => 100,

	];

	ob_start();

	$query = new WP_Query( $args );

	if ( $query->have_posts() )
	{

		echo '<ul>';

		while ( $query->have_posts() )
		{

			$query->the_post();
?>
			<li><a href="<?php  the_permalink() ?>" target="_blank"><?php the_title(); ?></a></li>
<?php
		} // end while

		echo '</ul>';

	} // end if
