I used SQLite’s built in fuzzy search and it is surprisingly powerful. I used it to for full text search over a magic the gathering card database and it was amazing.
Or did I just describe foundationDB?
I guess the real problem is that such a beast wouldn't have kibana, and people want kibana and put up with elasticsearch to get it.
Elastic Search, Amazon Open Search, Solr, etc. just wrapped Lucene up in a much easier to use HTTP / Rest API and then added bells and whistles like a coherent DSL, scripting, authentication and authorization, jobs, bulk API, etc. Then they built additional tools like Logstah and Kibana, which integrate using these APIs.
I'd call it elasticite and then (correctly!) be sued by both elastic and the sqlite orgs...
