Features inference
editFeatures inference
editSome URIs in Elasticsearch take a Feature enum.
Within NEST, route values on the URI are represented as classes that implement an interface, IUrlParameter.
Since enums cannot implement interfaces in C#, a route parameter that would be of type Feature is represented using the Features class that
the Feature enum implicitly converts to.
Constructor
editUsing the Features constructor directly is possible but rather involved
Features fieldString = Feature.Mappings | Feature.Aliases;
Expect("_mappings,_aliases")
.WhenSerializing(fieldString);
Here we new an GET index elasticsearch request which takes Indices and Features. Notice how we can use the Feature enum directly.
var request = new GetIndexRequest(All, Feature.Settings);
