如何在艾文的ElasticSearch中使用通配符字段？

Question

我想在ElasticSearch实例(艾文)中测试新的艾文。

我试过这个：

PUT /wildcard_test
{
  "mappings" : {
      "properties" : {
        "wildcard_field" : {
          "type" : "wildcard"
          }
        }
  }
}

我得到了这样的回应：

{
  "error" : {
    "root_cause" : [
      {
        "type" : "mapper_parsing_exception",
        "reason" : "No handler for type [wildcard] declared on field [wildcard_field]"
      }
    ],
    "type" : "mapper_parsing_exception",
    "reason" : "Failed to parse mapping [_doc]: No handler for type [wildcard] declared on field [wildcard_field]",
    "caused_by" : {
      "type" : "mapper_parsing_exception",
      "reason" : "No handler for type [wildcard] declared on field [wildcard_field]"
    }
  },
  "status" : 400
}

下面是有关实例的信息：

得到/得到/

{
  "name" : "...",
  "cluster_name" : "...",
  "cluster_uuid" : "...",
  "version" : {
    "number" : "7.9.3",
    "build_flavor" : "unknown",
    "build_type" : "unknown",
    "build_hash" : "c4138e51121ef06a6404866cddc601906fe5c868",
    "build_date" : "2020-10-16T10:36:16.141335Z",
    "build_snapshot" : false,
    "lucene_version" : "8.6.2",
    "minimum_wire_compatibility_version" : "6.8.0",
    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}

获取/_license

{
  "error" : {
    "root_cause" : [
      {
        "type" : "invalid_index_name_exception",
        "reason" : "Invalid index name [_license], must not start with '_'.",
        "index_uuid" : "_na_",
        "index" : "_license"
      }
    ],
    "type" : "invalid_index_name_exception",
    "reason" : "Invalid index name [_license], must not start with '_'.",
    "index_uuid" : "_na_",
    "index" : "_license"
  },
  "status" : 400
}

我的理解是，这个特性是由X提供的，我不知道它是否包含在Aiven的服务中。有什么办法让这件事成功吗？

Answer 1

尽管wildcard字段类型确实是加在第7.9节，但它(不幸的是)只能作为X订阅的一部分使用，我认为运行在Aiven上的是OSS，它缺少这个特性和其他X-包功能。
