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 So far I've come up with the plugin 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.
