Filter for particular field to exist

[the100rabh]

I am currently unable to figure out a way to make use of exists filter in kibana. eg.

{
    "constant_score" : {
        "filter" : {
            "exists" : { "field" : "user" }
        }
    }
}

I wish it was able to filter in kibana using this method.

There is an extension to the lucene query language for this:

_exists_:user

There is also:

_missing_:user

Hi
How can i make this work for a field which is an array? it doesn't seem to work for me if field is an array

The solution is for a query; how about as a filter?

I realize I'm responding to a comment from 2015, but better late than never.

You could make a Kibana filter consisting of a Lucene query string like so:

{
  "query": {
    "query_string": {
      "query": "_exists_:user"
    }
  }
}

@rashidkpc Where can I find the reference guide for this extension to the lucene query language?
