Thank you very much. It seemed like we were just duplicating a bunch of scheme-less json for no reason, but if ES can lose data, that's probably not a good idea.

Follow up: MongoDB is adding full-text search capabilities: https://www.youtube.com/watch?v=4QUGWnz-XaA
The v7 upgrade to a new cluster protocol (zen2) has improved things but overall the system has a long history of losing or destroying data. It's better to have a primary OLTP system that's ACID and reliable while using ES as the secondary search source. You can also remove the _source field if you just need matches without the original content.
It's common to see pattern used with a relational database since, as you can see, Mongo doesn't buy you much else as another document-store.
