When I run _GET indexName_ against ES, i get a definition of the index. How does one do that with the Nest library?

I've tried client.GetIndex but that doesn't seem to do the trick. And I don't see any metadata specific methods.

An example would be great.

Here are the index methods with NEST

```auto
var client = new ElasticClient();

// makes GET /<index> request
var getIndexResponse = client.GetIndex("<index>");

// makes GET /<index>/_settings request
var getIndexSettingsResponse = client.GetIndexSettings(i => i
    .Index("<index>")
);

// makes GET /<index>/_mapping request
var getMappingsResponse = client.GetMapping<object>(i => i
    .Index("<index>")
    .AllTypes()
);

```

@forloop This works generally, but for some indexes the call fails. I am on version 1.7.6 so that might be the problem.

For instance, _client.GetIndex(name);_ returns the following error:

`Could not convert string to boolean: no. Path 'index', line 1, position 181.`

Running _GET /valuations\_636727374057800495_ yields the following, so something can't be parsed properly.

What version of the NEST client are you using? NEST 1.x should be used with 1.7.6

I see. I'll just live with the errors since 1.x version is not code compatible with the latest NEST release.

[Elasticsearch 1.x is compatible with NEST 1.x](https://github.com/elastic/elasticsearch-net#compatibility-matrix), so you must use the latest NEST 1.x release, which is [NEST 1.9.2](https://www.nuget.org/packages/NEST/1.9.2). Note that Elasticsearch 1.7.6 and NEST 1.x are both end of life.

The equivalent methods in NEST 1.9.2 are

```auto
// makes GET /<index> request
var getIndexResponse = client.GetIndex(i => i.Index("<index>"));

// makes GET /<index>/_settings request
var getIndexSettingsResponse = client.GetIndexSettings(i => i
    .Index("<index>")
);

// makes GET /<index>/_mapping request
var getMappingsResponse = client.GetMapping<object>(i => i
    .Index("<index>")
    .Type("")
);

```
