I have two elastic indexes
Parent
Child
I have created a dashboard with visualizations that use both those indexes.
Both of the indexes have a field "family\_id". I can apply the family ID filter to filter the entire dashboard and this works fine!
However, I want to filter on Parent Age. So Lets say I apply a filter for parents with age 50, I want it to filter the Parent AND the child index. Almost like apply the filter to parents, then get the family\_ids and apply that filter down to children. Is that possible? If so how?

Hello @adwaitjoshi
Elasticsearch doesn't support joins. Denormalizing data is recommended. Can you supply the parent age data to the child documents?
