C# 如何使用NEST 1.x和C从ElasticSearch搜索/查询/获取/排序#

我为这个问题发送了两天的时间，但无法解决它。请告知

class Test_Market
    {
        public string x_ric { get; set; }
        public string date { get; set; }
        public string timestamp { get; set; }
        public string rdn_code { get; set; }
        public Dictionary<string, string> fids { get; set; }

    }

我对向Elasticsearch添加数据没有问题，但面临排序/查询/搜索的问题

这个代码没有问题

var node = new Uri("URL");
var ESsettings = new ConnectionSettings(node);
var client = new ElasticClient(ESsettings);
var response = client.Search<Test_Market>(s => s
                .Index("test-market-b")
                .Type("test_market").Size(10)
                );

---

timestamp

字段不应为

string

类型，而应为

date

。@Val我尝试了.Query（q=>q.Term（“日期”，“07-24-2018”）或.Query（q=>q.Term（“x_-ric”，“ABC”）它们没有给我任何价值。我的意思是在你的

测试市场

类中，

时间戳

应该定义为日期，而不是字符串查看文档中的1.x：

var node = new Uri("URL");
var ESsettings = new ConnectionSettings(node);
var client = new ElasticClient(ESsettings);
var response = client.Search<Test_Market>(s => s
                .Index("test-market-b")
                .Type("test_market").Size(10)
                );

var myData = new List<object>();
            foreach (var hit in response.Documents)
            {
                myData.Add(hit.timestamp);
            }

var responseXX = client.Search<Test_Market>(s => s
                .Index("test-market-b")
                .Type("test_market")
                .Size(1)
                .Sort(sort => sort.OnField( t=>t.timestamp).Descending())

                );

            var result = client.Search<Test_Market>(s => s
                .Query(q=>q
                    .Term("date","07-24-2018")
                    )
            );

var responseXX = client.Search<dynamic>(s => s
               .Query(q => q
                    .Match(m => m.OnField("x_ric").Query("AAA")))
             .Sort(sort => sort.OnField("timestamp").Descending())
                );

            var products = responseXX.Documents.ToList();
