Delete Mappingedit
Allows you to delete a mapping (type) along with its data. The REST endpoint is /{index}/{type}
with DELETE
method.

Most times, it make more sense to reindex the data into a fresh index compared to deleting large chunks of it.
Examplesedit
Using the default index and the inferred type name
this.ConnectedClient.DeleteMapping<ElasticSearchProject>()
or more explictly
this.ConnectedClient.DeleteMapping<ElasticSearchProject>("alternateindex","alternatetypename")
