Question

我正在尝试在Elasticsearch中创建一个嵌套文档。

结构：

title,name,comments

评论是一个嵌套的文档 - 在其中 - 评论＆amp; STAR_RATING。
内部评论，姓名和地址。

以下是下面提到的查询。

PUT /sounduu
    {
    "mappings": {
        "blogpost": {
            "properties": {
                "title": {
                    "type": "string"
                },
                "name": {
                    "type": "string"
                },
                "comments": {
                    "properties": {
                        "comment": {
                            "properties": {
                                "name": {
                                    "type": "string"
                                },
                                "address": {
                                    "type": "string"
                                }
                            }
                        },
                        "star_rating": {
                            "type": "long"
                        }
                    }
                }
            }
        }
    }
}


PUT /sounduu/blogpost/1
{
    "title": "someh_title",
    "name":"soundy",
    "comments": {
        "comment":"kuu",
        [{
             "name":"juwww",
             "address":"eeeey"
         },
         {
             "name":"jj",
             "address":oo"
        }]
    },
    "star_rating":6
}

错误：

{
   "error": {
      "root_cause": [
         {
            "type": "mapper_parsing_exception",
            "reason": "object mapping for [comments.comment] tried to parse field [comment] as object, but found a concrete value"
         }
      ],
      "type": "mapper_parsing_exception",
      "reason": "object mapping for [comments.comment] tried to parse field [comment] as object, but found a concrete value"
   },
   "status": 400
}

任何人都可以帮忙吗？

在PUT /sounduu/blogpost/1请求中，您试图将“comment”属性视为嵌套对象和字符串。

格式化您的请求的JSON，您可以观察到问题：

{
    "title": "someh_title",
    "name": "soundy",
    "comments": {
        "comment": "kuu",
        [{
            "name": "juwww",
            "address": "eeeey"
        },
        {
            "name": "jj",
            "address": oo"
        }]
    },
    "star_rating":6
}

您需要更新映射以包含“text”属性，并相应地移动"comment": "kuu"内容，或者从请求中省略它以使用当前映射。

这里的示例 - 对我来说，将所有内容分组是合乎逻辑的：

PUT /sounduu
    {
    "mappings": {
        "blogpost": {
            "properties": {
                "title": {
                    "type": "string"
                },
                "name": {
                    "type": "string"
                },
                "comments": {
                    "properties": {
                        "text" : {
                            "type": "string"
                        },
                        "name": {
                            "type": "string"
                        },
                        "address": {
                            "type": "string"
                        }
                    }
                },
                "star_rating": {
                    "type": "long"
                }
            }
        }
    }
}

索引请求将如下所示：

{
    "title": "someh_title",
    "name": "soundy",
    "comments": [
        {
            "text": "kuu",
            "name": "juwww",
            "address": "eeeey"
        },
        {
            "text": "kuu2",
            "name": "jj",
            "address": oo"
        }
    ],
    "star_rating":6
}

如果您使用的是ElasticSearch更高版本，则建议将“字符串”数据类型替换为“文本”。 ElasticSearch社区已放弃“字符串”。

更改后的请求应为：

 `PUT /sounduu
    {
    "mappings": {
        "blogpost": {
            "properties": {
                "title": {
                    "type": "text"
                },
                "name": {
                    "type": "text"
                },
                "comments": {
                    "properties": {
                        "text" : {
                            "type": "text"
                        },
                        "name": {
                            "type": "text"
                        },
                        "address": {
                            "type": "text"
                        }
                    }
                },
                "star_rating": {
                    "type": "long"
                }
                }
            }
        }
    }`
