Is it possible to get older versions of any document


(canavar) #1

Hi all,

I am definitely a newbie. I searched the group but could not find an answer
to my question. There is the cool Update API. Every update increases the
version number of the document by 1. I wonder if it is possible to get the
older versions of any document. I mean the _source of the document
specifically.
If it is possible then there would be no need for other versioning logic.

Thanks.

No. I don't think you can.
Version number is only used to help developpers managing concurrency when
updating documents.

Document content of previous version is not stored. Only the latest version
is in Lucene indexes.
