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.

Hi, I tried the file_path:*, it still show me the document with empty value.

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