Support KQL with Query String Queries

[ljak]

Query String Query make it really easy to write queries, without the DSL. It seems really close to the Lucene Query Syntax.

On the side, Kibana started, from the Lucene Query Syntax, its own query syntax called Kibana Query Language (KQL) : https://www.elastic.co/guide/en/kibana/current/kuery-query.html . Very similar to the Lucene Query Syntay, they recently added support for Nested Fields : https://www.elastic.co/guide/en/kibana/current/kuery-query.html#kuery-query-nested-field and elastic/kibana#47070

My request : could it be possible to have an ES query type (similar to the Query String query - maybe improves that one) to parse the KQL ? That new query string type will support natively nested fields ! Thanks.

Currently using elasticsearch npm package, and it only supports Query String Queries as far as I know

+1 This is exactly what I'm looking for also. I've even attempted to get kbn-es-query out of @elastic/kibana so I could use it as is to 'parse' my query which works peachy in Discover.

Nesting source is magical for the data I'm working with. It'd be equally magical if I had an obvious way (like Discover does) to work with a search like this: branchOrganizers.leafOrganizers.fieldList:{ CWPersonName.familyName: Erdman }
