I wanted to search for some data on the first index.  
Then I need to find the unique values of a specific field in the above search result, and search for the them in the second index.  
The names of the indices are different.  
How can I do this?

Thanks

You need to issue two separate requests. It is not possible to do tjis in a single query.
