WordPress Pagination Script Issue

Hello Everyone ??

I have question regarding pagination script. Currently I am using Simple Pagination for display custom post type records.

Everything is working good but when I pass some variable from URL and click to second page, next record is not displaying. Why I am not getting second results.

I am getting result if URL is:
https://localhost/example/my-search/
or
https://localhost/example/my-search/page/2/

I am not getting result if URL is:
https://localhost/example/my-search/page/2/?books=Internet&submit=search

Please I need your help to fix this issue.

My Code:

<?php
	$args = array (
		'post_type' => 'book',
		'post_status' => 'publish',
		'paged' => $paged,
		'posts_per_page' => -1
	);

	$temp = $wp_query; //Assign ordinal query to temp variable for later use
	$wp_query = null;
	$wp_query = new WP_Query($args);

	echo '<div class="result-count">Showing all '.$wp_query->post_count.' results</div>';

			if ( $wp_query->have_posts() ) :
				while ( $wp_query->have_posts() ) : $wp_query->the_post();

					echo '<div class="entry-content">';
						the_title();
					echo'</div>';

				endwhile;
			endif;
	echo '</div>';
?>
<nav>
	<?php
    	if(function_exists('wp_simple_pagination')) {
            wp_simple_pagination();
        }
    ?>

   <?php
        $wp_query = null;
        $wp_query = $temp; // Reset
   ?>
</nav>
