Using Elasticsearch.Net/NEST to search parent documents based on child attributes, where parent/child documents are stored separately

Question

I would like to use Elasticsearch.Net/NEST to search related documents. For example, I have:

Person:

id name address_id
-- ---- ----------
1  John 1
2  Mary         


        

Answer 1

I think the best place to look is at the NEST Unit Tests.

• Fluent Mapping Full Example Tests - Includes an example of setting Parent relationship.
• Has Parent Query
• Has Child Query
• Top Children Query

Also on the Nest Documentation Site there is a small snippet for running a has_child query. (Pretty much the same as the unit test)
