Use elastica with PagerFanta and dynamic querybuilder - symfony

Question

I have an application with symfony2 / doctrine 2 / elastica / fosElasticaBundle / pagerFanta.
I want to use a custom and dynamic queryBuilder in combination with pagerfanta and elastica. Not to transform the results but to prefilter them.
So far I was able to :
1. Use pagerfanta by itself with my custom queryBuilder :
$page = $request->get('page', 1);
$search = $request->get('search');
$querybuilder = $this->getDoctrine()->getRepository('AppBundle:FoodAnalytics\Recipe')->findByTopCategoryQueryBuilder($category);
$explorerManager = $this->get('explorer_manager');
$pagerFanta = $explorerManager->getPagerFanta($querybuilder, $page, 4);
$recipes = $pagerFanta->getCurrentPageResults();
Use Elastica with Pagerfanta but without my custom QueryBuilder :
$page = $request->get('page', 1);
$search = $request->get('search');
$finder = $this->container->get('fos_elastica.finder.website.recipe');
$pagerFanta = $finder->findPaginated($search);
$recipes = $pagerFanta->getCurrentPageResults();
Now, how can I also use my custom QueryBuilder ? I know you can set a custom one in elastica config but mine has to be dynamic = take an argument, so I'd like to set it in the controller. Is that possible ?

Answer 1

You can pass custom Elastica\Query to findPaginated method:
$query = new \Elastica\Query::create(new \Elastica\Query\Term(array(
'name' => $request->get('search')
));
$finder = $this->container->get('fos_elastica.finder.website.recipe');
$pagerFanta = $finder->findPaginated($query);
$recipes = $pagerFanta->getCurrentPageResults();
Maybe code is more clear and you can see how it works when you use just PagerFanta with ElasticaAdapter without FOSElasticaBundle:
// Searchable can be any valid searchable Elastica object. For example a Type or Index
$finder = new \Elastica\Index($elasticaClient, 'website.recipe');
// A Query can be any valid Elastica query (json, array, Query object)
$query = new \Elastica\Query::create(new \Elastica\Query\Term(array(
'name' => $request->get('search')
));
$elasticaAdapter = new \Pagerfanta\Adapter\ElasticaAdapter($finder, $query);
$paginator = new \Pagerfanta\Pagerfanta($elasticaAdapter);
$results = $paginator
->setMaxPerPage($limit)
->setCurrentPage($page)
->getCurrentPageResults();
