Elasticsearch.NET & NEST - search always returning 0 results

Question

I'm trying to search using the ElasticClient.Search method but no matter what terms I set, or field I search by, I always get 0 results.

Here is the structure of my POCO:

public class MyParent
{
    public MyChild MyChild { get; set; }
}

public class MyChild
{
    public string MyField { get; set; }
}

And then here is my actual search code:

string searchTerm = "myChild.myField";
string searchValue = "C";

Field searchField = new Field(searchTerm);

ISearchResponse<MyParent> result =
    Client.Search<MyParent>(s =>
        s.Query(q => q.Term(searchField, searchValue)));

if (result != null && 
    result.Documents != null && 
    result.Documents.Count != 0)
{
    ...
}

Any help appreciated!

I would get the raw query that is executed (from your result object) and run it in kibana — Z ., May 28 '18 at 15:08
Can you please tell me where inside the `ISearchResponse` object I get the raw query from? — Omar Himada, May 28 '18 at 15:13
also check is the result is successful and if there is an error message — Z ., May 28 '18 at 15:13
It is "Successful low level call on POST" but I don't see the raw query — Omar Himada, May 28 '18 at 15:14
`var query = Encoding.UTF8.GetString(result.RequestInformation.Request);` — Z ., May 28 '18 at 15:14
Ty! apparently the raw query for ES6 is `Encoding.UTF8.GetString(result.ApiCall.RequestBodyInBytes);` — Omar Himada, May 28 '18 at 15:16
my guess would be that it does not return anything... try a Match query instead of Term — Z ., May 28 '18 at 15:19
Match doesn't work and the raw query looks fine. I tried it out in Kibana and the query works there so... I don't get it — Omar Himada, May 28 '18 at 15:36
Use fiddler to sniff the raw http and look at what is different when you use Elastic console — Filip Cordas, May 28 '18 at 15:52

Found the problem. I wasn't setting the index! I changed my search code to this and it works:

ISearchResponse<MyParent> result =
    Client.Search<MyParent>(s =>
        s.Index("my_index_").Query(q => q.Term(searchField, searchValue)));
