Best way to manage filer form and result page - symfony

Question

What's the best way to manage filter page and result page in Symfony?
I have a controller that manage filter form and execute query. The result of this query must pass in another controller action. The result must show in another controller action because I used knp_paginator. If I render the result in same controller action of filter form, when change page the controller show filter form and not result.

this is the approach that I used:
Action for create find form:
public function findAction(Request $request)
{
$form = $this->createFindForm($request);
$form->handleRequest($request);
if(($form->isSubmitted() && !$request->isXmlHttpRequest()))
{
if(($this->isValidFindForm($form) && $form->isValid()))
{
$parm = $request->request->get('findForm');
return $this->redirect($this->generateUrl('list_documents',$parm));
}
}
return $this->render(
'myBundle:Documents:document\document_find.html.twig',
array('form' => $form->createView())
);
}
private function createFindForm(Request $request)
{
$form = $this->createForm(
new findDocumentType(
$this->getDoctrine()->getManager(),
$request
),
null,
array(
'action' => $this->generateUrl('find_documents'),
'method' => 'POST',
)
);
return $form;
}
I used $parm = $request->request->get('findForm'); to get the querystring. "findForm" is the name of my filter form.
The redirecting action :
public function listAction(Request $request)
{
$documents = $this->searchDocument($request);
$paginator = $this->get('knp_paginator');
$pagination = $paginator->paginate(
$documents,
$this->get('request')->query->get('page', 1)
);
return $this->render(
'myBundle:Documents:document\document_list.html.twig',
array('pagination' => $pagination)
);
}
The request is passed to search function (request contains querystring)
In search action:
private function searchDocument(Request $request)
{
$parm = $request->query;
$repository = $this->getDoctrine()->getRepository('docliteBundle:Document\\document');
$query = $repository
->createQueryBuilder('d');
....
With $request->query->get() I have access to all parameter.
Hope this help someone.
P.S. for the pagination I used KNP_paginator
