Hi,

I have a unit test that puts 10 object in Elastic and then uses a bool must match query to find certain results.  
I wrote the test when we used 7shards/index.  
Now we only use 3 and the test fails.  
Can someone explain why Elastic returns something different when using 3 shards instead of 7?

Kind regards

Hello,

What do you mean "returns something different"? Do you get different query results or different scoring?

Kind regards,
