Hi All.  
I hope all well there. 🙂

Guys, Can you please clear the below doubt?

As we already know we can't perform the join between two indexes like in the relational database, in NoSQL, it doesn't provide features like this. But I have come across the one plugin that is SIREN ([https://siren.io/getting-started/](https://siren.io/getting-started/)).

Is there anyone who has used this plugin for getting data from two indexes using this SIREN ES plugin?

Or what is the demerit of using the SIREN plugin?

Thanks in advance!
