I'm trying to limit the data I attach to emails by naming fields in `input.search.extract`. The examples I've found typically use something simple like `hits.total`, and that works. However, things like `hits.hits.0._source` don't result in anything being extracted.
Is it possible to pull things out of the hits and what is the syntax I should be using?
