Question

我将ONGR ElasticsearchDSL Bundle和Symfony 3一起使用，以经纬度坐标搜索城市列表，如下所示：

$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);

虽然这给我匹配的城市带来了很好的结果，但是我不清楚如何按照距源点的距离（在$ theSearch ['location']中找到）进行排序，以便使它们从最接近的位置到最远的位置排序？！

这是使用ElasticsearchDSL的正确方法，包括所需的排序。

$repository = $this->elasticsearchManager->getRepository(CityDocument::class);
$search = $repository->createSearch();

$geoQuery = new GeoDistanceQuery('geo', '50km', $theSearch['location']);
$search->addQuery($geoQuery, BoolQuery::FILTER);

$sort = new FieldSort('_geo_distance', null, [
    'geo' => $geoLocation,
    'order' => 'asc',
    'unit' => 'km',
    'mode' => 'min',
    'distance_type' => 'arc'
]);
$search->addSort($sort);

$documents = $repository->findDocuments($search);

在ONGR ElasticsearchDSL中按距离对结果进行排序
