I have a join mapping relationship where units is the parent and wells is child.
I'm trying to run this query to return the child but also include a field from the parent. This would only return the parent ID. How do i return a field in the parent document called "name"?
{
"query": {
"parent_id": {
"type": "wells",
"id": "units-1"
}
},
"runtime_mappings": {
"parent": {
"type": "keyword",
"script": "emit(doc['my_join_field#units'].value)"
}
},
"fields": [
{ "field": "parent" }
]
}
