I was able to include the pages where there are custom fields in search results but I managed not to display the content when there is nothing in the content. Is there a way to include the content of custom fields in the loop?
Something along the lines of get_post_custom() or get_post_meta() probably would suit your needs pretty well. You can feed either of them with get_the_ID() for the $post_id.
