Hi. I am trying to differentiate validation errors from intermittent errors from bulk index API. So let's say I tried to index 3 documents, and one failed.. I want to retry the indexing only if it was an intermittent error (I don't know, maybe node/shard couldn't accept write at that moment or whatever) and not for errors that would always happen like validation errors The documentation at [https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-bulk.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-bulk.html) doesn't list the possible enums of errors that can happen under response `items[].error.type`. Where can I find the list of types? ---

The `error.type` field is the name of the exception that caused the failure (with a bit of mangling) so can basically be anything. There isn't a definitive list of exceptions that might arise from indexing. ---
