Missing Filter

More info about missing filter is in the official elasticsearch docs

Returns documents that have only null values or no value in the original field.

Simple example

{
    "filter" : {
        "missing" : { "field" : "user" }
    }
}

And now the query via DSL:

$missingFilter = new MissingFilter('user');

$search = new Search();
$search->addFilter($missingFilter);

$queryArray = $search->toArray();
