WordPress Custom Query With Multiple Meta Key Value

I am new with WordPress development and I have found this query and I want pass multiple key and value in this query.

My Query is:

$querydetails = "
   SELECT wposts.*
   FROM $wpdb->posts wposts, $wpdb->postmeta wpostmeta
   WHERE wposts.ID = wpostmeta.post_id
		AND wpostmeta.meta_key = 'type' AND wpostmeta.meta_value = 'Collection1'
   AND wposts.post_status = 'publish'
   AND wposts.post_type = 'book'
   ORDER BY wposts.post_date DESC
";

I want add more statement with OR operator.

My Original Code is:

<?php
$querydetails = "
   SELECT wposts.*
   FROM $wpdb->posts wposts, $wpdb->postmeta wpostmeta
   WHERE wposts.ID = wpostmeta.post_id
		AND wpostmeta.meta_key = 'type' AND wpostmeta.meta_value = 'Collection1'
   AND wposts.post_status = 'publish'
   AND wposts.post_type = 'book'
   ORDER BY wposts.post_date DESC
";

$pageposts = $wpdb->get_results($querydetails, OBJECT);
?>

<?php if ($pageposts):
foreach ($pageposts as $post):
   setup_postdata($post); ?>

   <h2><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></h2>

<?php endforeach;
endif; ?>

Any Idea ??

I will appreciate if you guide me ??
