[SOLVED] How to build parent child relationship search in Elastic-search using Liferay API's?

How to build parent child relationship search in Elastic-search using Liferay API's?

We have a custom entity in Liferay called 'Publication'. It is indexed in Elastic-search and contains a field named 'journalArticleId'.

Based on our search requirements if some user searches for any keyword in the journal article we have to return the publication document which contains the 'journalArticleId' of the respective journal.

I found the solution for implementing this using Java API but I'm looking for the Liferay API to solve this.
