Elasticsearch::Persistence::Model::Find::ClassMethods#find_in_batches

Returns all models efficiently via the Elasticsearch's scan/scroll API

You can restrict the models being returned with a query.

The {http://rubydoc.info/gems/elasticsearch-api/Elasticsearch/API/Actions#search-instance_method Search API}
options are passed to the search method as parameters, all remaining options are passed
as the `:body` parameter.

The full {Persistence::Repository::Response::Results} instance is yielded to the passed
block in each batch, so you can access any of its properties; calling `to_a` will
convert the object to an Array of model instances.
