elasticsearch - 使用NEST和QueryRaw的Elasticsearch查询

我有以下 flex 搜索查询:

 {
    "query": {
        "filtered": {
            "query": {
                "multi_match": {
                    "query": "main",
                    "type": "cross_fields",
                    "fields": [
                        "field1^5",
                        "test",
                        "field2",
                        "abc"
                    ],
                    "operator": "and"
                }
            }
        }
    },
    "sort": [],
    "from": 0,
    "size": 20
}

我正在尝试使用NEST客户端进行Elastic Search并使用“ QueryRaw ”属性来运行此查询，但出现错误。

有人可以在我要去哪里的地方提供一些意见吗

var uri = new Uri("Elastic_Search_Cluster_Name");
var settings = new ConnectionSettings(uri, defaultIndex: "testIndex");
var client = new ElasticClient(settings);
var resp=client.Search<dynamic>(q =>
q.Type("mappingType").QueryRaw(inputRequest.ToString())
);

错误日志:

最佳答案

整个搜索请求无法传递到QueryRaw中。您只能将应该包含在"query"对象内的JSON请求传递到QueryRaw中。因此，如果将下面的JSON主体传递到QueryRaw中，它应该可以工作。

{
   "filtered": {
      "query": {
         "multi_match": {
            "query": "main",
            "type": "cross_fields",
            "fields": [
               "field1^5",
               "test",
               "field2",
               "abc"
            ],
            "operator": "and"
         }
      }
   }
}

但是"sort"，"from"和"size"对象不在"query"内，因此Nest无法解析您的请求。

您的Nest代码应如下所示:

var uri = new Uri("Elastic_Search_Cluster_Name");
var settings = new ConnectionSettings(uri, defaultIndex: "testIndex");
var client = new ElasticClient(settings);
var resp = client.Search<dynamic>(q => q
    .Type("mappingType")
    .QueryRaw(<raw query string>)
    .From(0)
    .Size(20)
);

我在上述Nest搜索请求中省略了Sort()，因为无论如何您都没有对其进行任何操作。
