How to search documents by version?

Is it possible to search documents in Elastic Search index by version? I try this:

curl -XGET eshost:9200/myindex/mytype/_search -d '{query:{match:{_version:"2"}}}'

But it does not work.

I need such a query to get all documents, that have never been updated.

Filter by version is not possible, you can just get the version of each document by set the parameter "version" = true

You might try

GET index/item/_search?pretty=version
{
    "version": true
}

you can search like normal and set version as true and it will return you count of all the versions for each document:

GET indextest/original/_search?pretty=true
{
    "version": true
}

Unfortunately, you cannot query or filter by _version - the problem is that that field is not indexed, so queries and filters cannot access it:

Try using version

Returns a version for each search hit.

{
    "version": true,
    "query" : {
        "term" : { "user" : "kimchy" }
    }
}
