Subject Re: Is that solr supports multi version operations?
Date Wed, 19 Sep 2018 05:40:29 GMT
I think if you try hard enough, it is possible to get Solr to keep
multiple documents that would normally keep only the latest version.
They will just have different internal lucene id.

This may of course break a lot of other things like SolrCloud and
possibly facet counts.

So, I would ask the actual business case first. It is entirely
possible that there are other ways to achieve the desired objectives.

Regards,
   Alex.
