Answer 1

It looks like you are calling ->appends on your variable called $books in several places within your view.
If $books is empty (i.e. null) this might be causing your problems.
I would suggest wrapping your $books in if is set functions as a starting point
if (isset($books) && $books != NULL) {
$books->appends(['query' => Input::get('query')])->render()
} else {
// Do something which tells the user that there are no books
}
An even better solution would be to handle all of the logic for the view in your controller and use something like a #forelse loop instead of a #foreach loop. This would make it easier to handle situations where you return an empty collection.
#forelse ($books as $book)
// Do your for each book markup
#empty
// Do markup which shows when you have no books
#endforelse
Corrections to the template
<?php $myArray = array(); ?>
#if (empty($myArray))
#foreach($books as $Afica)
<?php $collection = collect($Afica);?>
<article class="one-third">
