Question

我正在尝试使用dynamic_templates在ElasticSearch（版本2.3.4）中创建完成映射，以便稍后我可以通过点击myindex / _suggest uri来获得任何看起来像“名称”的建议。

以下是我如何设置它：

curl -XPUT "http://127.0.0.1:9200/myindex" -d'
{
  "mappings": {
    "document": {
      "dynamic_templates": [
        {
          "names": {
            "match_mapping_type": "string",
            "path_match": "*.name",
            "mapping": {
              "type": "string",
              "fields": {
                "completion":{
                  "type": "completion",
                  "analyzer": "standard",
                  "search_analyzer": "standard",
                  "payloads": true
                }
              }
            }
          }
        },
      ]
    }
  }
}'

以下是我在ES中的内容（使用elasticsearch-head插件查看内容）：

{
  "_index": "myindex",
  "_type": "mytype",
  "_id": "57b5123f3ca9d3ec007c285a",
  "_version": 2,
  "_score": 1,
  "_source": {
    "foo": {
      "name": "bar",
    }
  }
}

以下是我在_suggest uri上查询的内容：

{
    "foo_suggest" : {
        "text" : "bar",
        "completion" : {
            "field" : "foo.name.completion"
        }
    }
}

我得到的回复是“[foo.name.completion]不是完成建议字段”的错误：

RemoteTransportException[[Gorgeous George][127.0.0.1:9300][indices:data/read/suggest[s]]]; nested: ElasticsearchException[failed to execute suggest]; nested: ElasticsearchException[Field [foo.name.completion] is not a completion suggest field];

我离开了吗？我做错了什么/非法？我在索引创建时没有收到任何错误 - 只有在我尝试点击_suggest uri时才会失败（并且_search正常工作）。
