I have this code below in my WP function. Filters work very well when running $ args1 or $ args2 or $ args3 or $ args4, but when together all $ args stop working.

Also I would like to integrate the filter, that is, to be able to query $ args1 and $ args3 together, or $ args1 and $ args4 or $ args1 and $ args2 and so on.

I would like a filter like this:

Following is the code below:

//filtrar

add_action(‘wp_ajax_myfilter’, ‘filter_news’); // wp_ajax_{ACTION HERE}
add_action(‘wp_ajax_nopriv_myfilter’, ‘filter_news’);

function filter_news(){

// $args = array(
//     'post_type' => 'post',
//     'posts_per_page' => -1 ,  
//     'orderby' => 'date', // we will sort posts by date
//     'order'  => $_POST['date'], // ASC or DESC
//     'fields' => 'ids',             
// );


$args1 = array(  
    'fields' => 'ids',          
    'tax_query' => array(                
       array(               
        'taxonomy' => 'category',
        'field' => 'id',
        'terms' => $_POST['areafilter'],

       ),
    ),

);

$query1 = new WP_Query( $args1 );

$args2 = array(
    'fields' => 'ids',
    'tax_query' => array(
    array(              
        'taxonomy' => 'post_tag',
        'field' => 'id',
        'terms' => $_POST['assuntofilter'],

       ),            
    ),
);
$query2 = new WP_Query( $args2 );

$args3 = array( 
    'fields' => 'ids',       
    'date_query' => array(
        array( 
           'key' => 'mes',                             
           'month' => $_POST['mesfilter'],

        ),               
    ),

);

$query3 = new WP_Query( $args3 );

$args4 = array( 
    'fields' => 'ids',   
    'date_query' => array(            
        array(  
         //  'relation' => 'OR', 
          'key' => 'ano',                 
          'year' => $_POST['anofilter'],

         ),
    ),

);
$query4 = new WP_Query( $args4 );

$all_IDs = array_merge( $query4->posts);


$final_query = new WP_Query( array( 'post__in' => $all_IDs ) );


if(  $final_query->have_posts() ) :
    while( $final_query->have_posts() ):  $final_query->the_post();

       echo '<article id="post-'. $final_query->post->ID.'"  class="post-default ajax"> ';

        echo      '<p><span>'.the_category('Assunto:', '<br />').'</span>
