I'm trying to join 2 index in ES where I need to merge few columns of Index 1 and Index 2 respectively. I don't want to waste more time on recreating the index with the columns i wanted because my use case tends to change rapidly. Is there a way to query ES or in Kibana dashboard to visualize the content.?
This can be done using the Timelion plugin.
