I had seen a post ([Continous transforms accumulating delay, can be tweak for speed up? - #7 by Germain\_Pavot](https://discuss.elastic.co/t/continous-transforms-accumulating-delay-can-be-tweak-for-speed-up/239807/7)) in which `date_histogram` was suggested as potentially impacting use of date in the transform searches.

You're right, I do see in the searches a set of other terms taken in account that seems to vary with updated documents.

Thanks for the explanation; that makes sense. I just wanted to be sure I hadn't done something wrong.
