未在字段上声明类型[icu_collation_keyword]的处理程序

Question

我正在尝试使用映射创建索引。

使用URL : localhost:9200/test3?pretty方法: PUT和with body

{  
"mappings": {
"properties": {
  "name": {
    "type": "text",
    "fields": {
      "keyword": {
        "type": "keyword",
        "ignore_above": 256
      },
      "sort_da": {
        "type": "icu_collation_keyword",
        "index": false,
        "language": "da",
        "country": "DK",
        "variant": "@collation=phonebook"
      },
      "sort_de": {
        "type": "icu_collation_keyword",
        "index": false,
        "language": "de",
        "country": "DE",
        "variant": "@collation=phonebook"
      }
    }
  }
}

}}

我得到了以下异常

"type": "mapper_parsing_exception",
"reason": "no handler for type [icu_collation_keyword] declared on field [sort_de]"

我假设你必须先安装ICU插件。

可以使用插件管理器安装此插件：

sudo bin/elasticsearch-plugin install analysis-icu

该插件必须安装在集群中的每个节点上，并且每个节点都必须在安装后重启。
