Hi,
when following the guide regarding the version stuff all is fine:

| Elastic](https://www.elastic.co/blog/versioning)**
>
> Upcoming elasticsearch 0.15 has some very cool features baked into it, one of those is versioning. Each document indexed in elasticsearch is now versioned and this allow for some cool operations done ...
Now I wanted to have this in my java project and tried the following:
>
But the search results in version -1 although I would expect 1 like it
is the case for the curl experiment.
This is especially bad as I want to fill the version from the
retrieved object and when feeding with a negative version ES throws an
exception \*\*
What am I doing wrong?
Regards,
Peter.

You need to enable versioning to be returned, check this: [Elasticsearch Platform โ Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/reference/api/search/version.html). In Java its SearchRequestBuilder#setVersion.

Thank you very much, I joined this forum to find answer for why java api returning -1 as version. Glad i did a search before posting a question. New to elastic search thoroughly enjoying its features. Java integration is first class.
