Search Loop Double Result – Template Editing

Hello,
I have problem to put code.
Full code index.php:

<div class="smart_content" align="center">
<div align="left">
<?php if(is_tag()){
        }
        elseif (is_search() || is_tax()) {
        include (TEMPLATEPATH . '/search-result.php');
        }
        else {query_posts(array('orderby' => 'rand'));}?>
</div>
<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<?php include TEMPLATEPATH.'/product.php'; ?>
<?php endwhile; ?><div class="clear"></div>
<?php { wp_pagenavi(); } ?>
      <?php else : ?>
	<h2>Not Found</h2>
	<div class="bodycontent">Sorry, but you are looking for something that isn't here.</div>
      <?php endif; ?>
</div>

Here the problem:

<?php if(is_tag()){
        }
        elseif (is_search() || is_tax()) {
        include (TEMPLATEPATH . '/search-result.php');
        }
        else {query_posts(array('orderby' => 'rand'));}?>

<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<?php include TEMPLATEPATH.'/product.php'; ?>
<?php endwhile; ?>

I know the wrong is put
<?php if(is_tag()) ....
before the post <?php if (have_posts())
So, my search is double result. First result is what I want, the template is (TEMPLATEPATH . '/search-result.php') but after the footer I get same result with template <?php include TEMPLATEPATH.'/product.php'; ?>.

How I put the right code structure to get the right search result with templatepath search-result.php?
