Exists Filter

More info about exists filter is in the official elasticsearch docs

Returns documents that have at least one non-null value in the original field.

Simple example

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

And now the query via DSL:

$existsFilter = new ExistsFilter('user');
$constantScoreQuery = new ConstantScoreQuery($existsFilter);

$search = new Search();
$search->addQuery($constantScoreQuery);

$queryArray = $search->toArray();
