Prefix Filter

More info about prefix filter is in the official elasticsearch docs

Filters documents that have fields containing terms with a specified prefix.

Simple example

{
    "filter" : {
        "prefix" : { "user" : "ki" }
    }
}

And now the query via DSL:

$termFilter = new PrefixFilter('user', 'ki');

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

$queryArray = $search->toArray();
