WP_Query no result if keyword contains number

$args = [
        's' => $autocompleteTerm,
        'orderby' => 'modified',
        'fields' => 'all',
        'post_status' => array('publish','future'),
    ];

$posts_query = new WP_Query($args);
return $posts_query->get_posts();

$autocompleteTerm is what i am searching for, for example if i publish an article with title ‘top 10 candies’

and then search for ‘top 10’, return is empty

it works if i search for ‘top’ instead
