   Example migrated from Codex:

   Code sample for filtering an array of posts results and return an array of post objects which does not have the word “selfie” in the title.

   add_filter( 'posts_results', 'my_posts_results_filter' );
   
   function my_posts_results_filter( $posts ) {
   	$filtered_posts = array();
   	print_r( $posts );
   	foreach ( $posts as $post ) {
   		if ( false === strpos($post->post_title, 'selfie')) {
   			// safe to add non-selfie title post to array
   			$filtered_posts[] = $post;
   		}
   	}
   	return $filtered_posts ;
   }
