Show "Post" count by searching in Wordpress

Sometimes in Wordpress, we need to perform custom search in our blog or site. It is not difficult to perform custom search. When I wanted to show the number of post found after search, I got problem. After google about it, I found the following easy solution.

  echo wp_specialchars($s); // printing the keyword
  $allsearch = &new WP_Query("s=$s&showposts=-1");
  $count = $allsearch->post_count;
  echo ' (' . $count . ') '; // printing the founded post count
  wp_reset_query();

I wish this will help you.
