ElasticSearch-不区分大小写的巢状

如何解决ElasticSearch-不区分大小写的巢状

我试图在索引中搜索“ Example1”，但实际上只有在索引“ EXAMPLE1”中搜索确切值时，我才能获得结果。我会让这种搜索不敏感。有我的代码：

创建索引：

var createIndexResponse = client.Indices.Create(defaultIndex,c => c
                          .Map<Objectinindex>(mp => mp
                          .AutoMap())

搜索查询：

var pool = new SingleNodeConnectionPool(new Uri(_elasticsearchSettings.Uri));

var settings = new ConnectionSettings(pool)
.DefaultIndex(defaultIndex)
.disableDirectStreaming()
.PrettyJson();

var client = new Elasticclient(settings);

var searchResponse = client.SearchAsync<Objectinindex>(s => s
                    .Explain()
                    .source(sf => sf)
                    .Query(qn => qn
                    .MultiMatch(c => c
                    .Query(queryValue)))).Result;

索引对象：

    "hits": [
        {
            "_index": "sql","_type": "_doc","_id": "PkSsC4QBsIJTwWG9TUY1","_score": 17.879944,"_source": {
                "title": "EXAMPLE1"
            }
         }
