Is it possible to loop through the results of a query and update (add a scripted field in) another index based on data within the result set?

Another way to think about this is updating an index with a lookup value from another index.

You might be able to reindex through an ingest pipeline with an [enrich processor](https://www.elastic.co/guide/en/elasticsearch/reference/current/ingest-enriching-data.html)?
