Elasticsearch:根映射定义具有不受支持的参数index:not_analyzed

Question

大家好我正在尝试创建架构测试.

PUT /test
{
    "mappings": {
        "field1": {
            "type": "integer"
        },
        "field2": {  
            "type": "integer"
        },
        "field3": {
            "type": "string",
            "index": "not_analyzed"
        },
        "field4": {
            "type": "string",
            "analyzer": "autocomplete",
            "search_analyzer": "standard"
        }
    },
    "settings": {
        bla
        bla
        bla
    }
}

我收到以下错误

{
    "error": {
        "root_cause": [{
            "type": "mapper_parsing_exception",
            "reason": "Root mapping definition has unsupported parameters: [index : not_analyzed] [type : string]"
        }],
        "type": "mapper_parsing_exception",
        "reason": "Failed to parse mapping [featured]: Root mapping definition has unsupported parameters:  [index : not_analyzed] [type : string]",
        "caused_by": {
            "type": "mapper_parsing_exception",
            "reason": "Root mapping definition has unsupported parameters:  [index : not_analyzed] [type : string]"
        }
    },
    "status": 400
}

请帮我解决这个错误

你几乎在这里,你只是缺少一些东西:

PUT /test
{
  "mappings": {
    "type_name": {                <--- add the type name
      "properties": {             <--- enclose all field definitions in "properties"
        "field1": {
          "type": "integer"
        },
        "field2": {
          "type": "integer"
        },
        "field3": {
          "type": "string",
          "index": "not_analyzed"
        },
        "field4,": {
          "type": "string",
          "analyzer": "autocomplete",
          "search_analyzer": "standard"
        }
      }
    }
  },
  "settings": {
     ...
  }
}

UPDATE

如果索引已存在,您还可以修改映射,如下所示:

PUT test/_mapping/type_name
{
    "properties": {             <--- enclose all field definitions in "properties"
        "field1": {
          "type": "integer"
        },
        "field2": {
          "type": "integer"
        },
        "field3": {
          "type": "string",
          "index": "not_analyzed"
        },
        "field4,": {
          "type": "string",
          "analyzer": "autocomplete",
          "search_analyzer": "standard"
        }
    }
}

我希望上述答案适用于<7.0的弹性搜索，但是在7.0中，我们无法指定doc type，因此不再支持。在这种情况下，如果我们指定doc type，则会得到类似的错误。

我正在使用Elastic search 7.0和Nest C＃最新版本（6.6）。ES 7.0的某些重大更改导致了此问题。这是因为我们无法指定文件类型，而在NEST的6.6版中，他们使用的是文件类型。因此，为了解决NEST 7.0发行之前的问题，我们需要下载其Beta版软件包

请通过此链接进行修复

https://xyzcoder.github.io/elasticsearch/nest/2019/04/12/es-70-and-nest-mapping-error.html

编辑：现在发布NEST 7.0。NEST 7.0可与Elastic 7.0一起使用。有关详细信息，请参见此处的发行说明。

Answer 3

我正在运行 Elastic Search 版本 7.12

当我运行以下命令时

curl -H 'Content-Type: application/json' -XPUT 127.0.0.1:9200/movies?pretty -d '
{
    "mappings" : {
        "movie": {
            "properties" : {
                "year" : { "type": "date" }
            }
        }
    }   
}'

返回以下错误。

{
  "error" : {
    "root_cause" : [
      {
        "type" : "mapper_parsing_exception",
        "reason" : "Root mapping definition has unsupported parameters:  [movie : {properties={year={type=date}}}]"
      }
    ],
    "type" : "mapper_parsing_exception",
    "reason" : "Failed to parse mapping [_doc]: Root mapping definition has unsupported parameters:  [movie : {properties={year={type=date}}}]",
    "caused_by" : {
      "type" : "mapper_parsing_exception",
      "reason" : "Root mapping definition has unsupported parameters:  [movie : {properties={year={type=date}}}]"
    }
  },
  "status" : 400
}

为了缓解这种情况，请按如下方式修改查询中的 json。

curl -H 'Content-Type: application/json' -XPUT 127.0.0.1:9200/movies?pretty -d '
{
    "mappings" : {
        "properties" : {
            "year" : { "type": "date" }
        }
    }   
}'

注意：删除了“movie”:{} 层。现在可以了。

从 ES 7 开始，映射类型已被删除。您可以在此处阅读更多详细信息

如果您使用 Ruby On Rails，这意味着您可能需要document_type从模型或关注点中删除。

作为映射类型的替代方案，一种解决方案是对每个文档类型使用索引。

前：

module Searchable
  extend ActiveSupport::Concern

  included do
    include Elasticsearch::Model
    include Elasticsearch::Model::Callbacks
    index_name [Rails.env, Rails.application.class.module_parent_name.underscore].join('_')
    document_type self.name.downcase
  end
end

后：

module Searchable
  extend ActiveSupport::Concern

  included do
    include Elasticsearch::Model
    include Elasticsearch::Model::Callbacks
    index_name [Rails.env, Rails.application.class.module_parent_name.underscore, self.name.downcase].join('_')
  end
end

Answer 5

检查您的弹性版本。

我遇到这些问题是因为我查看了错误版本的文档。
