Php 如何使用elasticsearchDSL Builder创建父子内部命中查询

使用ONGR/ElasticsearchDSL，我试图添加一个父子内部命中查询。示例文档表明，正确的方法是

{
    "inner_hits" : {
        "children" : {
            "type" : {
                "article" : {
                    "query" : {
                        "match" : {"title" : "[actual query]"}
                    }
                }
            }
        }
    }
}
And now the query via DSL:

$matchQuery = new MatchQuery('title', '[actual query]');
$innerHit = new ParentInnerHit('children', 'article', $matchQuery);

$search = new Search();
$search->addInnerHit($innerHit);
$search->toArray();

所以在我的场景中，我做到了：

$termQuery = new TermQuery('user', $query);
$innerHit = new ParentInnerHit('child_type', 'parent_type', $termQuery);
$search->addInnerHit($innerHit);

我的问题是，我收到了错误消息：

Catchable fatal error: Argument 3 passed to
ONGR\ElasticsearchDSL\InerHit\NestedInnerHit::__construct()
must be an instance of ONGR\ElasticsearchDSL\Search,
instance of ONGR\ElasticsearchDSL\Query\TermLevel\TermQuery
give defined in ../ongr/elasticsearch-dsl/src/InnerHit/NestedInnerHit.php
on line 46

有什么想法或建议吗？

正如您从exception

ParentInnerHit

中所看到的，ParentInnerHit期待的是搜索而不是查询，这很有意义。要生成所需的查询，您必须：

$termQuery = new TermQuery('user', $query);
$searchObject = new Search();
$search->addQuery($termQuery);
$innerHit = new ParentInnerHit('child_type', 'parent_type', $searchObject);
$search->addInnerHit($innerHit);

我没有测试这个，但是你应该知道
