elasticsearch\Query $source

This option controls how the _source field is returned from the documents. For example, ['id', 'name'] means that only the id and name field should be returned from _source. If not set, it means retrieving the full _source field unless fields() are specified. Setting this option to false will disable return of the _source field, this means that only the primaryKey of a record will be available in the result.
