Thanks Mikko for your response.
I use Twenty Twelve 1.5.
This is the search.php:
<?php
/**
* The template for displaying Search Results pages
*
* @package WordPress
* @subpackage Twenty_Twelve
* @since Twenty Twelve 1.0
*/
get_header(); ?>
<section id=”primary” class=”site-content”>
<div id=”content” role=”main”>
<?php if ( have_posts() ) : ?>
<header class=”page-header”>
<h1 class=”page-title”><?php printf( __( ‘Search Results for: %s’, ‘twentytwelve’ ), ‘<span>’ . get_search_query() . ‘</span>’ ); ?></h1>
</header>
<?php twentytwelve_content_nav( ‘nav-above’ ); ?>
<?php /* Start the Loop */ ?>
<?php while ( have_posts() ) : the_post(); ?>
<?php get_template_part( ‘content’, get_post_format() ); ?>
<?php endwhile; ?>
<?php twentytwelve_content_nav( ‘nav-below’ ); ?>
<?php else : ?>
<article id=”post-0″ class=”post no-results not-found”>
<header class=”entry-header”>
<h1 class=”entry-title”><?php _e( ‘Nothing Found’, ‘twentytwelve’ ); ?></h1>
</header>
<div class=”entry-content”>
<p><?php _e( ‘Sorry, but nothing matched your search criteria. Please try again with some different keywords.’, ‘twentytwelve’ ); ?></p>
<?php get_search_form(); ?>
</div><!– .entry-content –>
</article><!– #post-0 –>
<?php endif; ?>
</div><!– #content –>
</section><!– #primary –>
<?php get_sidebar(); ?>
<?php get_footer(); ?>
And this is the content.php:
<?php
/**

?>
<article id=”post-<?php the_ID(); ?>” <?php post_class(); ?>>
<?php if ( is_sticky() && is_home() && ! is_paged() ) : ?>
<div class=”featured-post”>
<?php _e( ‘Featured post’, ‘twentytwelve’ ); ?>
</div>
<?php endif; ?>
<header class=”entry-header”>
<?php if ( ! post_password_required() && ! is_attachment() ) :
the_post_thumbnail();
endif; ?>
<?php if ( is_single() ) : ?>
<h1 class=”entry-title”><?php the_title(); ?></h1>
<?php else : ?>
<h1 class=”entry-title”>
” rel=”bookmark”><?php the_title(); ?>
</h1>
<?php endif; // is_single() ?>
<?php if ( comments_open() ) : ?>

<?php if ( is_search() ) : // Only display Excerpts for Search ?>
<div class=”entry-summary”>
<?php the_excerpt(); ?>
</div><!– .entry-summary –>
<?php else : ?>
<div class=”entry-content”>
<?php the_content( __( ‘Continue reading <span class=”meta-nav”>→</span>’, ‘twentytwelve’ ) ); ?>

</div><!– .entry-content –>
<?php endif; ?>
<footer class=”entry-meta”>
<?php twentytwelve_entry_meta(); ?>
<?php edit_post_link( __( ‘Edit’, ‘twentytwelve’ ), ‘<span class=”edit-link”>’, ‘</span>’ ); ?>
<?php if ( is_singular() && get_the_author_meta( ‘description’ ) && is_multi_author() ) : // If a user has filled out their description and this is a multi-author blog, show a bio on their entries. ?>
<div class=”author-info”>
