我有收藏用户，所有文档的结构如下：

{
  "username": "de",
  "userId": 123456,
  "followers":[
    {
      "userId":123,
      "username": "bc",
    },
    {
      "userId": 456,
      "username": "ac",
    }
}

还有更多文件：

{
  "username": "a",
  "userId": 123456,
  "followers":[
    {
      "userId": 456,
      "username": "ab",
    }
}

我想索引“用户名”字段（父级，不在关注者中）。我喜欢以下：

curl -XPUT http://localhost:9200/users -d '
{  
   "mappings":{
      "multisearch":{
         "properties":{
            "username":{
                 "type":"string",
                 "analyzer":"partial_name",
                 "search_analyzer":"partial_name",
                 "index_analyzer":"partial_name"
               }
            }
          }
      },
         "settings":{
            "analysis":{
               "filter":{
                  "name_ngrams":{
                     "side":"front",
                     "max_gram":20,
                     "min_gram":2,
                     "type":"NGram"
                  }
               },
               "analyzer":{
                  "full_name":{
                     "filter":[
                        "standard",
                        "lowercase",
                        "asciifolding"
                     ],
                     "type":"custom",
                     "tokenizer":"standard"
                  },
                  "partial_name":{
                     "filter":[
                        "standard",
                        "lowercase",
                        "asciifolding",
                        "name_ngrams"
                     ],
                     "type":"custom",
                     "tokenizer":"standard"
                  }
               }
            }
         }
}'

我将新的 mongodb 河添加到 elasticsearch：

curl -XPUT 'localhost:9200/_river/mongodb/_meta' -d '{
    "type": "mongodb",
    "mongodb": {
        "servers": [
            {"host": "Konoha", "port": 27018},
            {"host": "Konoha", "port": 27027}
        ],
        "db": "mydatabase",
        "collection": "users",
        "options": {
            "secondary_read_preference": true,
            "drop_collection": true
        },
        "gridfs": false
    },
    "index": {
        "name": "users",
        "type": "multisearch"
    }
}'

现在我尝试使用关键字“manh”进行搜索，我在浏览器中运行：

http://localhost:9200/users/multisearch/_search?pretty=true&q=username:abc

结果是我上面描述的两个文件。我认为 ElasticSearch 还会在关注者字段中索引字段用户名吗？

我只想要行有用户名=abc（父）

你能帮我只索引父字段用户名吗？

感谢您的帮助:)
