Official Support for UpdateByQuery?

Hi all,

I'm a newbie to ES, I wanna know whether it is officially supported to update documents by query? I've done several researches in the mailing list and the official document on http://www.elasticsearch.org/. So far I've come up with the plugin https://github.com/yakaz/elasticsearch-action-updatebyquery. I've tried this one and it seems pretty cool, but it is not released in any official build.

Any official support for this feature? I don't want to manually scroll over all the 100GB data to do bulk update on the client side.

Thanks
