NEST Search not found any result - elasticsearch

Question

Just find out about nest. I already insert some number of document in Elastic Search. Right now I want to search the data based on my type, subcriberId. I did run through curl and it works just fine. But when I tried using nest, no result found.
My curl which work:
http://localhost:9200/20160902/_search?q=subscribeId:aca0ca1a-c96a-4534-ab0e-f844b81499b7
My NEST code:
var local = new Uri("http://localhost:9200");
var settings = new ConnectionSettings(local);
var elastic = new ElasticClient(settings);
var response = elastic.Search<IntegrationLog>(s => s
.Index(DateTime.Now.ToString("yyyyMMdd"))
.Type("integrationlog")
.Query(q => q
.Term(p => p.SubscribeId, new Guid("aca0ca1a-c96a-4534-ab0e-f844b81499b7"))
)
);
Can someone point what I did wrong?

A key difference between your curl request and your NEST query is that the former is using a query_string query and the latter, a term query. A query_string query input undergoes analysis at query time whilst a term query input does not so depending on how subscribeId is analyzed (or not), you may see different results. Additionally, your curl request is searching across all document types within the index 20160902.
To perform the exact same query in NEST as your curl request would be
void Main()
{
var pool = new SingleNodeConnectionPool(new Uri("http://localhost:9200"));
var connectionSettings = new ConnectionSettings(pool)
// set up NEST with the convention to use the type name
// "integrationlog" for the IntegrationLog
// POCO type
.InferMappingFor<IntegrationLog>(m => m
.TypeName("integrationlog")
);
var client = new ElasticClient(connectionSettings);
var searchResponse = client.Search<IntegrationLog>(s => s
.Index("20160902")
// search across all types. Note that documents found
// will be deserialized into instances of the
// IntegrationLog type
.AllTypes()
.Query(q => q
// use query_string query
.QueryString(qs => qs
.Fields(f => f
.Field(ff => ff.SubscribeId)
)
.Query("aca0ca1a-c96a-4534-ab0e-f844b81499b7")
)
)
);
}
public class IntegrationLog
{
public Guid SubscribeId { get; set; }
}
This yields
POST http://localhost:9200/20160902/_search
{
"query": {
"query_string": {
"query": "aca0ca1a-c96a-4534-ab0e-f844b81499b7",
"fields": [
"subscribeId"
]
}
}
}
this specifies the query_string query in the body of the request which is analogous to using the q query string parameter to specify the query.
