Is it possible to combine a parent document and a child document of the same parent in to a single doc with fields from both documents using either reindex or scripting?

For example, let's say parent document have fields A,B,C,D and child documents have fields D,E,F,G,H. I want every parent-child pair to be a single doc with fields A,B,C,D,E,F,G,H. If there are 3 children for a single parent, i need three documents where each document has child plus parent fields.

I know it's possible to do it using an external client. Wanted to know if this can be done with in the cluster.

You can always use nested mapping and put child fields into an inner object in parent dac mapping – sramalingam24 May 19 '18 at 12:13
Yes, the problem here is that the all the docs in the existing mapping uses parent-child already. – Nithin Chandy May 19 '18 at 14:23
so, what's the problem with parent child for you? – Mysterion May 21 '18 at 09:20
