对于使用 Nest 或 Elasticsearch.Net 客户端的某些请求，响应时间超过 500 毫秒。当直接使用 http 客户端或抛出 kibana 接口时，相同的查询大约需要 1-2ms。如果数据库中的文档很少，则会发生这种情况。

我在 localhost 上使用以下设置：

PUT suggestions
{
  "settings": {
    "number_of_shards": 1, 
    "number_of_replicas": 0
  },
  "mappings": {
    "suggestionelement": {
      "properties": {
        "suggest": {
          "type": "completion",
          "max_input_length": 100
        }
      }
    }
  }
}

并索引以下文档：

POST suggestions/suggestionelement
{
  "suggest": {
    "input": "this is just some text for suggestion a",
    "weight": 1
  }
}

POST suggestions/suggestionelement
{
  "suggest": {
    "input": "this is just some text for suggestion b",
    "weight": 2
  }
}

POST suggestions/suggestionelement
{
  "suggest": {
    "input": "this is just some text for suggestion c",
    "weight": 3
  }
}

POST suggestions/suggestionelement
{
  "suggest": {
    "input": "this is just some text for suggestion d",
    "weight": 4
  }
}

POST suggestions/suggestionelement
{
  "suggest": {
    "input": "this is just some text for suggestion e",
    "weight": 5
  }
}

当运行“这只是一些文本”的建议（完成）查询抛出 Nest 或 Elasticsearch.Net 客户端时，它需要超过 500 毫秒。从 kibana 或直接使用 httpclient 运行相同的程序只需不到 2 毫秒

已经做了好几天了……有什么想法吗？

我使用的 C# 代码：

        var nodes = new Uri[] { new Uri("http://localhost:9200") };
        var connectionPool = new StaticConnectionPool(nodes);

        var connectionSettings = new ConnectionSettings(connectionPool)
           .DefaultIndex("suggestions")
           .RequestTimeout(TimeSpan.FromSeconds(30));

        var searchEngineClient = new ElasticClient(connectionSettings);

        for (int i = 0; i < 10; i++)
        {
            return await searchEngineClient.SearchAsync<SuggestionElement>(s =>
                s.Suggest(ss => ss
                    .Completion("sentence-suggest", c => c
                    .Field(f => f.Suggest)
                    .Prefix("this is just some text for")
                    .Size(1000))));
        };
