Order post objects by date when typing

Hi,

I have a post object field and I use the acf/fields/post_object/query hook to query the posts ordered by date. This is my function:

function my_post_object_query($args) {
    $args['orderby'] = 'date';
    $args['order'] = 'DESC';

    return $args;
}
add_filter('acf/fields/post_object/query', 'my_post_object_query');

It works great. When I focus in the post object field it returns the posts ordered by date. But if I type something in the post object field they are not ordered by date. I would like it returns posts wich contain the string typed but ordered by date. Is this possible? How can I do it?

Thanks.
