Configuring Routing in ElasticSearch Using NEST and Attribute Mapping

I am trying to customize my mapping using Attribute Based Display

I need to set up routing, make it mandatory, and set the object that I am indexing to a specific object.

Is it possible? Has anyone done this?

You can use IdProperty

attribute property ElasticType

:

[ElasticType(Name = "mydocument", IdProperty = "docDate")]
public class MyDocument
{
    [ElasticProperty(Name = docDate)]
    public DateTime DocDate { get; set; }

...


This sets the value stored in a field _id

in elasticsearch that is used for routing .

First you need to do the routing needed when creating the index, for example:

client.CreateIndex("my-index",
    d => d
        .Mappings(mapping => mapping
            .Map<MyObject>(map => map
                .RoutingField(routing => routing
                    .Required(true))
                .AutoMap()
            )
        ));

Second, you need to add the routing value when indexing your document, for example:

var result = client.Index<MyObject>(
        myObject,
        selector => selector
            .Id(myObject.ObjectId)/*to avoid "random" ids*/
            .Routing(routingValue)); //or in your case, myObject.MySpecialProperty


Finally, you need to provide a routing value when you search.

client.Search<MyObject>(query => query.Query(q => q.MatchAll()).Routing(routingValue));
