我正在使用 5.1 版本学习 ElasticSearch。我有一个索引“mycontent”和一个类型“simpledocument”。我在尝试检查 simpledocument 类型的建议/完成功能时遇到错误“illegal_argument_exception no mapping found for field”。详情如下：

GET _search
{
  "suggest":{
    "my-suggestion":{
      "prefix":"ap",
      "completion":{
        "field":"suggest"
      }
    }
  }
}

这给了我回应：

{
  "took": 4,
  "timed_out": false,
  "_shards": {
    "total": 6,
    "successful": 5,
    "failed": 1,
    "failures": [
      {
        "shard": 0,
        "index": ".kibana",
        "reason": {
          "type": "illegal_argument_exception",
          "reason": "no mapping found for field [suggest]"
        }
      }
    ]
  },
......

映射中确实有建议字段：

GET _mapping/simpledocument

{
  "mycontent": {
    "mappings": {
      "simpledocument": {
        "properties": {
          "description": {
            "type": "text",
            "fields": {
              "keyword": { …
