【问题标题】：How many nested query in elasticsearch?elasticsearch中有多少嵌套查询？
【发布时间】：2015-11-23 18:38:26
【问题描述】：

我将 ElaticSearch 1.7.2 用于我的项目并使用 marvel 插件来测试查询。我的查询模板是这样的：

GET myindex/_search
{
  "query": {
    "filtered": {
      "query": {
        "bool": {
          "minimum_should_match": 1,
          "should": [
            {
              "nested": {
                "path": "mypath",
                "query": {
                  "bool": {
                    "should": [
                      {
                        "terms": {
                          "mypath.field": []
                        }
                      },
                      {
                        "match": {
                          "mypath.desc": "abb"
                        }
                      }
                    ],
                    "minimum_number_should_match": 1
                  }
                }
              }
            },
            {
              "nested": {
                "path": "mypath02",
                "query": {

                          "mypath02.one": "1"
                        }
                      },
                      {
                        "match": {
                          "mypath02.two": "2"
                        }
                      },
                      {

                    ],
                    "minimum_number_should_match": 1
                  }
                }
              }
            },
            {

                        }
                      }
                    ]
                  }
                }
              }
            },
            {
              "nested": {
                "path": "mypath04",

                          "mypath04.hash": [
                            "39651",
                            "cecc5"
                          ]
                        }
                      },
                      {
                        "nested": {

                                    "mypath05.hash01": "afcee"
                                  }
                                },
                                {
                                  "match": {
                                    "mypath05.hash02": "aceff"
                                  }
                                }
                              ],
                              "minimum_number_should_match": 1
                            }
                          }
                        }
                      }
                    ]
                  }
                }
              }
            }
          ]
        }
      }
    }
  }
}

第一次执行时，我收到了这条消息：

请求未能到达服务器（状态码：0）：

Elasticsearch 可能无法访问，或者您可能需要检查您的 CORS 设置。如果启用了 CORS，请尝试关闭 Sense 的 Basic 设置（齿轮图标）下的身份验证支持。这将导致浏览器对 CORS 的执行不那么严格。请检查奇迹文档以获取更多信息。

更新 11.23.2015 在文件中添加更多日志信息：elasticsearch.log

我关注了这个帖子：ES reachable from curl but not from Marvel/Sense

但什么都没有解决！

实际上，当我从上面的查询中仅删除一个嵌套查询时，它运行成功。

请帮我解决这个问题！谢谢。

我的问题已解决 11.23.2015

我没有准确地删除作为嵌套对象的字段类型，更新索引映射和我的查询成功运行。

【问题讨论】：

你能发布你说它有效的查询吗？
只需从我的查询中删除一个嵌套查询，例如，删除包含："nested": { "path": "mypath02", ..... 的嵌套查询
这没有意义。无论查询如何，来自 Sense 的查询都会失败或失败。因为失败来自连接，而不是查询本身。我建议再次对此进行测试，并提出正确的复制步骤列表。
@Andrei Stefan 输出消息让我感到困惑！我不知道失败与否。 “Elasticsearch 可能无法访问，或者您可能需要检查您的 CORS 设置......”。我使用 curl 命令行的结果相同。
@Tr.Crab，你的问题让我们感到困惑。我们也不知道是什么失败了，而且没有额外的信息（你如何提交查询，发生了什么，你的客户端和 ES 位于哪里......），我们仍然不会。

【解决方案1】：

我仍然不知道您的客户端/服务器在哪里（同一台机器，不同的机器）以及您在做什么（运行 curl 可能会有很多不同）。处理您给我们的内容，这是我的答案（如果不是屏幕截图，我会将其作为评论插入它的基本角色）。假设默认 ES 设置和配置。

请检查是否

为您的 ElastiSearch 服务器启用了 CORS
在接受的 CORS 来源中，您的客户端/curl 尝试从其中连接
CORS 已启用，如果启用（并且您正在使用 Sense）禁用 Sense 的基本身份验证支持
您提交给 ElasticSearch 的 HTTP 请求（请记住，这不仅仅是您的搜索查询）符合要求的 LENGTH 标准

有关条件的详细信息，请参见下面的屏幕截图：
