Hi,
Are there any current examples or documentation about how to index a GeoJson format string into a document field with the NEST library? I'd also be keen to know whether using GeoJson with Elasticsearch is supported/recommended.
I'm specifically interested in points and polygons but can't get either to work, and all the forum posts I can find about this seem out of date. e.g. the examples [here](https://github.com/elastic/elasticsearch-net/issues/2444) linked in a couple different places reference SetJsonSerializerSettingsModifier on ConnectionSettings which doesn't exist in Nest anymore.
At the moment I'm stuck trying to deserialize a GeoJson string into a GeoPolygonShape and getting serializer errors.
Thanks for your help!
