I am setting up CCS with a remote cluster that contains 2 indexes using Kibana's data (kibana_sample_data_ecommerce and kibana_sample_data_flights).
When performing a search across these 2 indexes, I noticed that the data from kibana_sample_data_flights always appears first. Is this the default behaviour of CCS results where all matching results from 1 index appears first followed by matching results from the other index?
Is there a way to mix and match the results from the 2 indexes?
