I'm a newbie installing elasticsearch and app search on AWS ec2. I got elastic search working on an Ubuntu instance and I can add documents to it using Postman locally. Then I installed app-search on a local VMWare Linux instance (I can't get it working on AWS unfortunately, but that's a problem for another day) and pointed it to the elasticsearch server and I can add documents here as well. But Postman and App Search are using two different indexes and the docs I add in Postman aren't showing up in the App search application. How do I tell app-search which index to use so it shares documents with Postman? I don't see a setting anywhere.
Thanks.
