Here is why I want to do this . 1. My unique key is a http URL, doctorURL. 2. If I do a look up based on URL , I am bound to face issues with character escaping and all. 3. To avoid that I was using a UUID for look up , but in SolrCloud it generates unique per replica , which is not acceptable. 4. Now I see that the mandatory _version_ field has a unique value per document and and not unique per replica , so I am exploring the use of _version_ to do a look up only and not neccesarily use it as a unique key, is it do able in that case ?
