We running this query and get the error below even though both documents exists and are stored in the same shard. Any idea on why this doesn't work?
GET an-alias/a-type/_search
{
"query": {
"has_child": {
"type": "xxx",
"query": {
"term": {
"id": "123456"
}
}
}
},

]
}

```
It works just fine with the same dataset on other clusters with the same version of elasticsearch.
Kind regards,
