弹性搜索索引模板 [英] Elasticsearch-groovy index template

问题描述

有没有办法用elasticsearch-groovy或elasticsearch-java的API定义索引模板？我想在其上应用设置（定制分析器）和映射（在场上应用分析器）。 文档仅指index templatex但不显示一个vaild示例，如何将它们应用于groovy关闭。文档中显示的示例在数据（源）字段中添加了设置。

编辑：@Val感谢您的回复，但如果我使用来源字段如下：

  def templateR = client.admin.indices .putTemplate {
 nametemplate_name
 source {
 templatetemplate_ *
} 
} .actionGet（）
  

...这导致编译器错误： MissingMethodException没有方法的签名：... source（） code>。以下代码：

  def templateR = client.admin.indices.putTemplate {
 namelemato_template
模板lemato_ *
设置{
 number_of_shards = 1 
} 
} .actionGet（）
  

给我编译器错误没有这样的属性：number_of_shards 。我不知道我是否使用封闭委员会a>正确。是否像 .asMap（）缺少？

解决方案

elasticsearch-groovy绝对支持创建/删除索引模板。 来源关闭可能包含您可以为索引模板。这样的事情应该有效。

  PutIndexTemplateResponse response = client.admin.indices.putTemplate {
 namemy_template
 source {
 templateindex_ *
 settings {
 index {
 number_of_shards = 5 
 number_of_replicas = 1 
} 
} 
 mappings { 
 //你的映射定义
} 
 aliases {
 //你的别名
} 
} 
} .actionGet（）
  

Is there any way to define an index template with the API of elasticsearch-groovy or elasticsearch-java? I want to apply "settings" (custom analyzers) and "mappings" (apply analyzer on fields) on it. The documentation only refers to index templatex but does not show a vaild example, how to apply them in a groovy closure. The example shown in the docs, adds the "settings" in the data (source) field.

edit: @Val Thank you for your reply, but if I use the source field as follows:

    def templateR = client.admin.indices.putTemplate {
        name "template_name"
        source {
            template "template_*"         
        }
    }.actionGet()

... this results in a compiler-error: MissingMethodException No signature of method: ...source(). The following code:

    def templateR = client.admin.indices.putTemplate {
        name "lemato_template"
        template "lemato_*"
        settings {
            number_of_shards= 1      
        }            
    }.actionGet() 

gives me the compiler error No such property: number_of_shards. I'm not sure if I use the closure delegation correctly. Is something like .asMap() missing?

解决方案

elasticsearch-groovy definitely provides support for creating/deleting index templates. The source closure may contain anything you can define for index templates. Something like this should work.

PutIndexTemplateResponse response = client.admin.indices.putTemplate {
  name "my_template"
  source {
    template "index_*"
    settings {
      index {
        number_of_shards = 5
        number_of_replicas = 1
      }
    }
    mappings {
       // your mapping definitions
    }
    aliases {
       // your aliases
    }
  }
}.actionGet()
