I'm using ONGR ElasticsearchDSL Bundle together with Symfony 3 to search through a list of citys by lat/lon coordinates, like so:
$repository = $this->elasticsearchManager->getRepository(CityDocument::class);
$search = $repository->createSearch();
$boolQuery = new BoolQuery();
$boolQuery->add(new MatchAllQuery());
$geoQuery = new GeoDistanceQuery('geo', '50km', $theSearch['location']);
$boolQuery->add($geoQuery, BoolQuery::FILTER);
$search->addQuery($boolQuery);
$documents = $repository->findDocuments($search);
While this gives me a good result with matching cities, I am unclear on how to sort those by distance from my source point (found in $theSearch['location']), so that I get them ordererd from closest to farthest?!
This is the correct way to use ElasticsearchDSL including sort you need.
