我们在ES中使用以下设置：

简而言之，我们使用两种不同的类型---包装和包装。收件人。此外，与包关联的收件人也存储在ES中。

现在，如果我们搜索：

{
  "query": {
    "query_string": {
      "query": "james@example.com",
      "fields": [
        "packages.recipientId.email"
      ],
      "default_operator": "OR"
    }
  },
  "size": "50",
  "from": "0",
  "sort": {
    "id": {
      "order": "asc"
    }
  }
}

虽然该特定收件人确实存在，但ES并未返回任何记录。但如果我们搜索如下：

{
  "query": {
    "query_string": {
      "query": "james@example.com",
      "fields": [
        "recipients.email"
      ],
      "default_operator": "OR"
    }
  },
  "size": "50",
  "from": "0",
  "sort": {
    "id": {
      "order": "asc"
    }
  }
}

ES正在返回记录。我不明白为什么搜索在上述两种情况下表现不同。

您能否建议我们需要更改/更正哪些内容，以便在这两种情况下都能进行搜索？

Answer 1

您必须执行嵌套查询才能查询嵌套字段：

＆＃34;由于嵌套文档始终被屏蔽到父文档，因此嵌套文档永远不能在嵌套查询的范围之外访问。＆＃34; http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-nested-type.html http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/query-dsl-nested-query.html

嵌套字段上的弹性搜索不起作用
