elasticsearch / elastica限制嵌套结果

Question

是否可以限制嵌套字段的结果？

我有店主和商店，对于我的搜索结果，我想只获得2个商店而不是所有者的所有元素。

我的设置是foselasticabundle 5.0 + elasticsearch 5.4.3

我用以下查询尝试过：

$query = new Query();
$query->setParams(
    [
        'query' => [
            'bool' => [
                'must' => [
                    [
                        'match' => [
                            '_all' => $term,
                        ],
                    ],
                    [
                        'nested' => [
                            'path' => 'shops',
                            'score_mode' => 'max',
                            'inner_hits' => [
                                'size' => 2,
                            ],
                            'query' => [
                                'match_all' => ['boost' => 1.0],
                            ],
                        ],
                    ],
                ],
            ],
        ],
    ]
);
$found = $this->index->getType('owner')->search($query);

$query = new Query(); $query->setParams( [ 'query' => [ 'bool' => [ 'must' => [ [ 'match' => [ '_all' => $term, ], ], [ 'nested' => [ 'path' => 'shops', 'score_mode' => 'max', 'inner_hits' => [ 'size' => 2, ], 'query' => [ 'match_all' => ['boost' => 1.0], ], ], ], ], ], ], ] ); $found = $this->index->getType('owner')->search($query);

查询有效，但忽略size参数

类型定义：

这是一个示例文档： types: owner: properties: name: { boost: 10, analyzer: snowball } created: { type: date } shops: type: nested properties: name: ~ address: type: nested properties: city: ~ street: ~ zip: ~ persistence: driver: orm model: AppBundle\Entity\Owner provider: ~ finder: ~
