How to enable automatic search results in WordPress

something like this in your page template, ideally after endwhile (if any)

<?php 
$theQuery = strtolower(trim(get_the_title()));
$args = ('s=".$theQuery ."&showposts=5');
$search_query = new WP_Query($args);
if ($search_query->have_posts()) :
    while ($search_query->have_posts()) : 
        $search_query->the_post();

        //do your stuff

    endwhile;
endif;
?>
