Using Pagination with custom findAll()

In my model I use custom findAll() as I need an extra join:

PHP Code:

public function findAll(int $limit = 0, int $offset = 0)
{
    $this->select('documents.*');
    $this->select('authors.name AS author_name');
    $this->join('authors', 'authors.id = documents.author_id', 'left');

    return parent::findAll($limit, $offset);
} 


Then my controller is a simple code like this:

PHP Code:

$model = new DocumentsModel();
$model->like('authors.name', 'John');
$documents = $model->findAll(); 


This worked great until I tried Pagination ($model->paginate()):

Code:

Unknown column 'authors.name' in 'where clause'

This problem is caused by Model::paginate() calling BaseBuilder::countAllResults() which doesn't use JOIN and so there is no authors.name column.

Can you suggest how can I rework my code to make things works, please?
