It works, I have used it to store documents as a NoSQL db, it's a Document search engine and in fact lucene is extremely good as a key/value storage. I have never missed documents in Elasticsearch... in Mongo... well... so many times to never use it again...

Hi, I have seen that NodeBB has a Database Abstraction Layer (DBAL), I wonder if you guys have ever thought of implementing Elasticsearch a DB, if not... I'm doing it!
