Named Queries using Nest and Elastic Search

Question

I'd like to name my queries that I send to my elastic search instance (version 2.3) so i can see the name in my log file. I use a .net application which uses NEST.2.1.1 to interact with the elastic search index. According to the ES documentation I should be able to use _name to give a name to my query but there's no method called that available, there is something called .Stats which claims to do the same thing but this just doesn't work.

Answer 1

All query descriptors have method to set name.

For example, range:

var response = client.Search<Product>(s => s
    .Query(q => q.Range(dr => dr.Name("_range").Field(f => f.Price1).LessThan(1)))
    );

which produces following query to ES:

{
    "query" : {
        "range" : {
            "price1" : {
                "_name" : "_range",
                "lt" : 1.0
            }
        }
    }
}

Hope it helps.
