I am following this eg => https://opensourceconnections.com/blog/2016/09/09/better-recsys-elasticsearch/.
But Instead of using array(as shown in the example) I want to create Parent-child structure for user-video model.
I tried few things but not getting expected output.
So my question is, can we use Significant Terms Aggregation with parent-child structure?
Thanks in advance!
No, joins like that won’t work with significant_terms. You need the related terms in the same doc.
ok thanks for ur reply!
