Below is a must do code for anyone working with custom post types in WordPress. It includes those custom post types in the search results of WordPress.

// MAKE CUSTOM POST TYPES SEARCHABLE
function searchAll( $query ) {
 if ( $query->is_search ) { $query->set( 'post_type', array( 'site', 'plugin', 'theme', 'person' )); } 
 return $query;

 return $vars;
}
add_filter( 'request', 'custom_feed_request' );
