Is there any way I can index multiple child documents by query.

Let’s say I have 10K product document and I have customer to whom all 10k orders are applicable. I am storing product as parent and customer as child. Now I want to add same customer to all products.

Can I add 10k child, one under each parent, at once or by query instead of adding one by one?

I am not aware of any way to do what you want within Elasticsearch so you may need to do it externally. If you are not already I would recommmend you use [the bulk API](https://www.elastic.co/guide/en/elasticsearch/reference/8.12/docs-bulk.html) to add the documents.

Is there any option to normalize the data before loading to achieve the same?

I do not understand what you mean. Could you please elaborate?

As far as I know there is no way to do this irrespective of how data is structured.
