elasticsearch doesn't returns all hits - symfony

Question

I'm using Symfony 2.3 and ElasticSearchBundle 3.0. I implemented two fields for the search. The search works correctly but it doesn't display all results. For example: when I search for the a keyword, the number of hits are 33 hits but it returns only 10 results.

public function searchEngineAction(Request $request) {
$finder = $this->container->get('fos_elastica.index.hortis.business');
// get data from both fields
$querystring = strip_tags($request->get('name'));
$querystring2 = strip_tags($request->get('location'));
$boolQuery = new \Elastica\Query\Bool();
// if both fields are empty then display all businesses
if (empty($querystring) and empty($querystring2)) {
$query = new \Elastica\Query\MatchAll();
$boolQuery->addMust($query);
} else {
// create a boolean query
if (!empty($querystring)) {
$fieldQuery = new \Elastica\Query\QueryString();
$fieldQuery->setFields(array('name', 'activities.principal'));
$fieldQuery->setQuery($querystring);
$boolQuery->addMust($fieldQuery);
}
if (!empty($querystring2)) {
$fieldQuery2 = new \Elastica\Query\QueryString();
$fieldQuery2->setFields(array(
'gouvernaurat', 'delegation', 'postal_code'));
$fieldQuery2->setQuery($querystring2);
$boolQuery->addMust($fieldQuery2);
}
}
// select only enbaled business
$enabled = new \Elastica\Query\Term();
$enabled->setTerm('enabled', true);
$boolQuery->addMust($enabled);
$findAll = \Elastica\Query::create($boolQuery);
$findAll->setSize(27);
// trigger search function
$elasticaResultSet = $finder->search($findAll);
dump($elasticaResultSet);
// get results from
$findbusinesses = $elasticaResultSet->getResults();
$noresult = '';
if (!$findbusinesses) {
$noresult = 'no result';
}
$em = $this->getDoctrine()->getManager();
$FrontSettings = $em->getRepository('TotoAdminBundle:FrontSettings')->getFrontSettings();
if (!$FrontSettings) {
throw $this->createNotFoundException('Unable to find frontSettings entity');
}
// get all categories and activities
$categories = $em->getRepository('TotoAdminBundle:Category')
->findBy(array(), array('order' => 'ASC'));
if (!$categories) {
throw $this->createNotFoundException('unable to find categories and activities');
}
$paginator = $this->get('knp_paginator');
$businesses = $paginator->paginate(
$findbusinesses, $this->get('request')->query->get('page', 1)/* page number */, 9/* limit per page */
);
return $this->render('TotoFrontBundle:Front:search_result.html.twig', array(
'querystring' => $querystring, 'businesses' => $businesses,
'FrontSettings' => $FrontSettings, 'noresult' => $noresult,
'categories' => $categories,
));
}
How can I display the all the hits?

Answer 1

Elasticsearch by default only returns the first 10 results. This setting can be modified by specifing the from and size parameters. Note that it rarely makes sense to display all results on one page, instead use a pagination with a controllable amount of viewed items.
If you want all hits on one page also consider using the scroll api as deep pagination can get very inefficiently when having a high amount of results.
