Wildcard facet filter

Hi All,

I am using the ElasticSearch Perl module
Is it possible to add wildcard facet filter to the below?

$result = $es->search( 
    facets  => { 
        my_facet => { 
            terms => { field => webhost, size => 3 }, 
            facet_filterb => { 
                _timestamp => { 
                    'gte' => 'now-1h', 
                    'lte' => 'now', 
                }, 
            } 
        }, 
    } 
); 

Thanks in advance

Nick
