Solr to get latest version of documents

[krishna prasad <kr...@gmail.com>]

I have a docs as follows:

{docid:1,version:1}
{docid:1,version:2}
{docid:2,version:1}
{docid:2,version:2}
{docid:2,version:3}
{docid:3,version:1}
{docid:3,version:2}


I need to get all the docs which are of the latest version per each docid.

o/p

{docid:1,version:2}
{docid:2,version:3}
{docid:3,version:2}

Can give some hints on how to do it.

Solr will overwrite the documents as they are indexed. So if they are
indexed in the order shown in your email you will get the correct versions.
