How should the C# code look like when I'm searching with coordinates?  
I've tried to do it like a regular search but nothing seems to happen.

The regular search code is:

```
            var searchResponse = lowlevelClient.Search<string>(new
        {
            from = 0,
            size = 10,
            query = new
            {
                match = new
                {
                    fName = "name"
                }
            }
        });

        //THIS IS THE CODE I'VE TRIED TO SEARCH WITH:    
    
        var searchResponse = lowlevelClient.Search<string>(new
        {
            from = 0,
            size = 10,
            query = new
            {
                geo_bounding_box = new
                {
                    location = new
                    {
                        top_left = new
                        {
                            lat = 45,
                            lon = -55.80
                        },
                        top_right = new
                        {
                            lat = 21,
                            lon = -21.10
                        }
                    }
                }
            }
        });

```

What am I doing wrong?

In order to form a bounding box, you need to supply diagonally opposite coordinates for the box, usually `top_left` and `bottom_right`.

But what should I type instead of the "Project" class? And what does it contains

`Project` is the POCO type that represents/maps to the shape of the JSON within `_source` for a particular type within an index.

Take a look at the [NEST getting started guide](https://www.elastic.co/guide/en/elasticsearch/client/net-api/current/nest-getting-started.html) for detailed information on how to get started with the high level client.
