Regarding the ingest timestamp, I recommend [this](https://discuss.elastic.co/t/dec-12th-2018-en-elasticsearch-automatically-adding-a-timestamp-to-documents/159314).

Regarding your scripted metric: Will you have duplicates in the data? E.g. what if a person updates the contact information? I wonder if you additionally want the _latest_ value. Now you return the 1st. Which might not even be the 1st in terms of time or index order, but the 1st that 1 shard answers.
