Not working

I just installed Relevanssi and activated it. I’ve also done the indexing but whenever I try to search for something on my website, it just shows the results as if I didn’t Relevanssi at all.

Here’s my search.php code

<?php
/**
 * search form
 */
?>
<center><form role="search" method="get" id="search-form" action="<?php echo esc_url( home_url( '/' ) ); ?>">
    <div class="search-wrap">
       <input type="search" placeholder="<?php echo esc_attr( 'Search…', 'presentation' ); ?>" name="s" id="search-input" value="<?php echo esc_attr( get_search_query() ); ?>" />
    </div>
</form></center>
