Elasticsearch: Min and Max Children Query with Nested Datatypes

Elasticsearch does not support min_children and max_children for nested datatypes by default (see: issue #10043). In case you need this behavior, this gist provides an alternative solution. Please note that I haven't benchmarked it against join queries.

Alternative solution

To support min_children and max_children for your nested query, all you have to do is to use a function_score query. To make this more concrete: you have an index called Person with the following mapping:

first_name (text)
email (text)

	* Automated inclusion of services with Fluxible
	*
	* The services are used on the server side as a resource. They fetch
	* an endpoint and return the data. Right now for each resource, you
	* need to manually include the file.
	*
	* The code sample needs to be placed in the /services/ directory of
	* your application - and be named index.js. To register all your
	* services, all you have to do:
