What is the ElasticSearch equivalent for an SQL subquery?

Question

Can you nest queries logically in ElasticSearch, so the output of one query is the input to another query. Another, way to ask is how can I chain or pipe queries together?

Answer 1

That is totally correct, you must programm a subquery in your favorite programming language. An example can be found here:
