These are above curl, for es2 cluster and es7 cluster

What can be the case the query is not working properly. While using "minimum_should_match" : 1 we are getting zero count,

is it correct way to go ahead.

There might be some wrong with the query, can you help me in that

Also note when I fire them individually, I hope I am not making some silly mistake, but I am almost sure I am not missing anything.
