ElasticSearch Low Level Client search using anonymous type

Elastic Stack Elasticsearch
1

Hi,

We are exploring Elastic search to see if it fits into our application requirements.

We would want to search using anonymous type, here is what i found in the documentation -

var searchResponse = lowlevelClient.Search<StringResponse>("people", PostData.Serializable(new
{
    from = 0,
    size = 10,
    query = new
    {
        wildcard= new
        {
            firstName = new
            {
                value = "Martijn"
            }
        }
    }
}));

var successful = searchResponse.Success;
var responseJson = searchResponse.Body;

I would want to search on firstName.keyword field but i couldn't specify a . (dot)

firstName.keyword

on wildcard search field and it gives a compilation error.

i'm using NEST .NET library.

Any help on this please.

Hi, @gjahagir.

This is possible with anonymous types but requires a workaround because the properties cannot contain period characters. You could achieve it with something like this:

var searchResponse = lowlevelClient.Search<StringResponse>("people", PostData.Serializable(new
{
    from = 0,
    size = 10,
    query = new
    {
        wildcard= new
        {
            firstName = new Dictionary<string, object>
            {
                ["firstname.keyword"] = "Martijn",
            }
        }
    }
}));
