Unlimited Search Results

Hello,

I’m trying to make my search results ignore the 5 post limit I have for my front end loop. The “show 5 posts” is setup in the backend under Settings. I’ve seen online that you can easily add this snippet:

<?php $posts=query_posts($query_string . '&posts_per_page=-1'); ?>

However, no luck. That snippet makes my search not work and return no results. I have pasted my entire search.php below so you can examine it and find something I’m missing. I just want it so search results can be shown more than 5 at a time.

Thank you! My search.php is below:

<?php get_header(); ?>

<section id="content" class="row display">

<div class="eight columns">

	<h2><?php echo('Search Results for'); ?> "<?php echo get_search_query(); ?>"</h2>

        <!-- This is where I added the above snippet with no luck. -->
	<?php if ( have_posts()) : while (have_posts()) : the_post(); ?>

		<article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>

			<div class="one columns" id="search_thumb">
				<?php if ( has_post_thumbnail() ) {
						the_post_thumbnail( array(100,100) );
					}
				?>
			</div>

			<div class="eleven columns" id="search_body">
				<h3><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h3>
				<?php the_excerpt(); ?>
			</div>

		</article>

		<hr>

	<?php endwhile; ?>

		<div class="post_nav">
			<p><?php posts_nav_link(); ?></p>
		</div>

	<?php else : ?>

		<?php echo 'Sorry, no posts matched your criteria.' ?>

	<?php endif; ?>

</div>

<?php get_sidebar(); ?>

<?php get_footer(); ?>

Also, to avoid some other questions, I’m using Foundation Framework by Zurb for my theme’s layout. Thanks again!
