* In a nutshell, currently, SQL acts as a <i>translator</i>, allowing traditional SQL queries to be executed against
* Elasticsearch indices without any modifications. Do note that SQL does <i>not</i> try to hide Elasticsearch or
* abstract it in anyway; rather it maps the given SQL, if possible, to one (at the moment) query DSL. Of course,
