Hi,

I am trying to filter out field without "null/empty" value in Kibana, but when I try to use operator exist. THen it still show me docs without any value. Just wondering is there a way to filter only see documents without null value?

Hi kenneth,

Try to use `file_path: *`  
Using this we are asking for some content in that field.

And then I also try it in "add filter" with operator "is" , value "\*", and it is not showing me any documents at all

You can specify the exact query that you want to apply, if you click on `Edit as Query DSL`.
