Hello everyone,  
I have a few questions:

1. Is there a list of all possible error return values?  
I've found only this:  
[https://www.elastic.co/guide/en/elasticsearch/client/javascript-api/current/errors.html](https://www.elastic.co/guide/en/elasticsearch/client/javascript-api/current/errors.html)  
But i'm not sure, that it's the complete one.

2. Are error codes, which could be returned by ES, similar to http error codes? Are there any differences?
