ElasticSearch Connection settings

Question

I just created ElasticSearch class and find some codes for elasticsearch connection settings but i know i am using NEST 7.0 and these codes i found are lower version than 7.0 so, how i can change to current version because i am getting some errors. Thanks in advance.

private static readonly ConnectionSettings connSettings = new ConnectionSettings(new Uri("http://localhost:9200/"))
                       .DefaultIndex("change_history")
                      .DefaultMappingFor(m => m
                       .Add(typeof(ChangeLog), "change_history"));
        private static readonly ElasticClient elasticClient = new ElasticClient(connSettings);

especially the defaultmapping part :)

The configuration options documentation has an example. Adapted for your example

private static readonly ConnectionSettings connSettings = 
    new ConnectionSettings(new Uri("http://localhost:9200/"))
        .DefaultIndex("change_history")
        .DefaultMappingFor<ChangeLog>(m => m
            .IndexName("change_history")
        );

private static readonly ElasticClient elasticClient = new ElasticClient(connSettings);
