Hi @galadh

If the query is like this: &type=typeA,typeB, then you need to add a query for each type listed. It should be something like this:

if (isset($_GET["type"]) && $_GET["type"]!='') {
    
    // get the listed types in an array
    $types = explode(',', $_GET[ "type" ]);
    
    // initialize the meta query
    $add_args['meta_query']['relation'] = 'OR';
    
    // loop through the types and add it to the query
    foreach( $types as $type ){
        $add_args['meta_query'] []= array(
            'key' => 'tipo_lemma',
            'value' => '"'. $type .'"',
            'compare' => 'LIKE'
        );
    }

}

I hope this helps 🙂
