count #

Counts documents in a collection.

A query can be provided to alter the count result, otherwise returns the total number of documents in the collection.

This method also supports the Koncorde Filters DSL to match documents by passing the lang argument with the value koncorde.
Koncorde filters will be translated into an Elasticsearch query.

Koncorde bool operator and regexp clause are not supported for search queries.
