How to use Facts Manager node
Facts Manager node is created especially for Engage. But based on your business use cases, you can use this node to fetch the questions, related topics, facts, and so on.
For example, in a K-Graph named “FAQ - Fact mngr“, we have created Facts with the Topic "Voice Search" and the Relationships “Description”, “Benefit“, “Optimization“, ”Implementation” in it.
...
If you want to know all the relationships associated with the topic Voice search, you can use the Fact Manager node and get the result.

Sample code for the function node:Code Block var _ = global.get('lodash'); _.set(msg, 'payload.orbita.facts.topic',"Voice search") return msg;Select the K-Graph and select Relationships from the populate field in the Facts Manager node.
