Search in admin help

Hello Guys,

I have custom post type with some custom columns from custom fields and taxonomies in admin area in post view.
The thing is when I try to use the search whats on the right side above the custom columns it wont search the custom columns.

Here is example of the code what I am using for the custom columns:

add_filter( 'manage_edit-listings_columns', 'my_edit_listings_columns' ) ;

function my_edit_listings_columns( $columns ) {

	$columns = array(
		'cb' => '<input type="checkbox" />',
		'title' => __( 'Listing Title' ),
		'address' => __( 'Address' ),
		'price' => __( 'Price' ),
		'author' => __( 'Agent' ),
		'property_style' => __( 'Style' ),
		'date' => __( 'Published' ),
	);

	return $columns;
} // END function

add_action( 'manage_listings_posts_custom_column', 'my_manage_listings_columns', 10, 2 );

function my_manage_listings_columns( $column, $post_id ) {
	global $post;

	switch( $column ) {

	// Address Column
	case 'address' :
		$address = get_post_meta( $post_id, 'address', true );
		if ( empty( $address ) )
			echo __( 'Unknown' );
		else
			printf( __( '%s ' ), $address );
	break;

	// Price Column
	case 'price' :
		$price = get_post_meta( $post_id, 'price', true );
		if ( empty( $price ) )
			echo __( 'Unknown' );
		else
			printf( __( '<span class="green"> $ %s</span>' ), $price );
	break;

	// Style ( Taxonomy ) Column
	case 'property_style' :
		$terms = get_the_terms( $post_id, 'property_style' );
		if ( !empty( $terms ) ) {
			$out = array();
			foreach ( $terms as $term ) {
				$out[] = sprintf( ' <a href="%s">%s</a>',
					esc_url( add_query_arg( array( 'post_type' => $post->post_type, 'property_style' => $term->slug ), 'edit.php' ) ),
					esc_html( sanitize_term_field( 'name', $term->name, $term->term_id, 'property_style', 'display' ) )
				);
			}
			echo join( ' ', $out );
		}
			else {
				_e( ' ' );
			}
	break;
	}}

And the sorting code:

add_filter( 'manage_edit-listings_sortable_columns', 'devpress_listings_sortable_columns' );
function devpress_listings_sortable_columns( $columns ) {
	$columns['price'] = 'price';
	return $columns;
} // END function

add_action( 'load-edit.php', 'devpress_edit_listings_load' );
function devpress_edit_listings_load() {
	add_filter( 'request', 'devpress_sort_price' );
}
function devpress_sort_price( $vars ) {
	if ( isset( $vars['listings'] ) && 'price' == $vars['listings'] ) {
		if ( isset( $vars['orderby'] ) && 'duration' == $vars['orderby'] ) {
			$vars = array_merge(
				$vars,
				array(
					'meta_key' => 'price',
					'orderby' => 'meta_value_num'
				)
			);
		}
	}
	return $vars;
}

I am using the same code on my older wordpress install and only difference is that now I am using Advance Custom Fields plugin for the custom fields. The search works fine on my older install.
Can you guys please help me to figure out how to add the custom columns to the search. Or what I am doing wrong here.

Thanks a lot.
