				* (such as max retries or timeout reached, bad authentication, etc...) or Elasticsearch itself returned an error (could 
				* not parse the request, bad query, missing field, etc...). If it is an Elasticsearch error, the `ServerError` property 
				* on the response will contain the the actual error that was returned.  The inner exception will always contain the 
				* root causing exception.
				*                                  
				* 2) UnexpectedElasticsearchClientException:  These are unknown exceptions, for instance a response from Elasticsearch not
				* properly deserialized.  These are usually bugs and should be reported.  This excpetion also inherits from ElasticsearchClientException
				* so an additional catch block isn't necessary, but can be helpful in distinguishing between the two.
				*
				* 3) Development time exceptions: These are CLR exceptions like ArgumentException, NullArgumentException etc... that are thrown
				* when an API in the client is misused.  These should not be handled as you want to know about them during development.
