We want to use Elasticsearch as primary data source, and we also want to keep track of changes of document, so we want to store all the versions of a document.

As a solution will be to hide previous document versions from the index, is this possible?

I'd probably index the document twice:

- One in the live index using the same `_id` always so updates will overwrite any existing document.
- One in the historical index using id+timestamp as the `_id` so all versions will be kept.

Can you please advise why to use also timestamp in the `_id`?

Better idea. Don't set any id and let elasticsearch create one for you.

Ok, thanks.

Can you please also advise if it is possible to use a processor, or any other tool, to automatically add a new document in the historical index when a new documented is added in or updated in live index?
