hi there ,
Can I aggregate on time series depending on state? e.g.
if a group of people took a pill on different occasions. and I want to see the impact of the group blood pressure on the continuing week. can I do this kind of aggregation?
It is super hard to answer this question without the data model. As it sounds that you need some context from older actions, it might make sense to take a look at the entity centric indexing approach.
There is a talk by Mark out there, that might be worth watching (plus searching for entity centric indexing should give some more hints).

At elasticon 2015 the video guys forgot to hit "record" for a lot of talks (unsurprisingly they didn't get the 2016 contract).
A re-run of that talk is here: https://www.youtube.com/watch?v=yBf7oeJKH2Y
