How to display the number of results in wordpress

Open your search template file, search.php. In it, search for the following:

<h2 class="pagetitle">Search Results</h2>

Now replace this with:

<h2 class="pagetitle">Search Result for <?php /* Search Count */ $allsearch = &new WP_Query("s=$s&showposts=-1"); $key = wp_specialchars($s, 1); $count = $allsearch->post_count; _e(''); _e('<span class="search-terms">'); echo $key; _e('</span>'); _e(' &mdash; '); echo $count . ' '; _e('articles'); wp_reset_query(); ?></h2>

For showing own avatar registered at Gravatar, add the following to functions.php

function get_ssl_avatar($avatar) {
   $avatar = preg_replace('/.*\/avatar\/(.*)\?s=([\d]+)&.*/','<img src="https://secure.gravatar.com/avatar/$1?s=$2" class="avatar avatar-$2" height="$2" width="$2">',$avatar);
   return $avatar;
}
add_filter('get_avatar', 'get_ssl_avatar');
