I have a special link with a filter, so I filter things with slugs through the link, for example

mydomain.com/filter/?technology=angular&category=software-development

and it shows the chosen jobs

Now, I want to show jobs with different id’s but with the same slug, like here:

mydomain.com/filter/?bullhorn_id=2979,2090

I tried this variation

https://itds.pl/filter/?bullhorn_id=2979&bullhorn_id=2903

and it’s not working
With one ID it works perfectly
Could please someone help me? I’m not good in PHP
here is part of a code that generates link

 if(isset($_GET['bullhorn_id'])){
                        $bullhorn = explode(',',$_GET['bullhorn_id']);
                        if(count($bullhorn)>=0){                                
                            for($p=0;$p<count($bullhorn);$p++){                                  
                                $filter[] = array( 'taxonomy' => 'bullhorn_id', 'field' => 'slug', 'terms' => $bullhorn[$p]  );
                            } 
                        }
                        else{
                            $filter[] = array( 'taxonomy' => 'bullhorn_id', 'field' => 'slug', 'terms' => $_GET['bullhorn_id']  );
                        }
                    }

Oh and BTW it’s taxanomy
