Solr嵌套文档-从孩子那里获得父母

Question

这是我的Solr嵌套文档的当前方案：

<?php
$meeting = $xml->MEET;
print_r($meeting);
?>

查询：

Type: Product
--  Type: Category
--  Type: ProductAttribute
--  --  Type: ProductAttributeValue
--  --  Type: ProductAttributeValue

示例数据格式：

http://localhost:8983/solr/MYCORE/select?q=Type:Product&rows=100&fl=*,[child parentFilter="Type:Product"]

仅在第二级查询将检索我的结果。

但是我想在3级查询并检索1级数据。

例如

[

    "Path": 1,
    "PathNew":"1.Product",

            "Type": "ProductAttributeValue",
            "PAVName": "Vista Home"
          },
          {
            "id": "pav9_pa5_p1",
            "Path": 3,
            "PathNew":"3.Product.ProductAttribute.ProductAttributeValue",
            "Type": "ProductAttributeValue",
            "PAVName": "Vista Premium"
          }
        ]
      }
    ]
  }
]

它将退回所有台式机产品以及笔记本类别

但是，如果我想从8GB的ProductAttributeValue中检索数据，并且仅检索那些以“ RAM”作为ProductAttribute且以“ 8GB”作为其ProductAttributeValue的产品

在第三级查询时从第一级检索数据的查询是什么？
