How to extend filter ? in question archive page url

I think it may be possible with https://localhost/mysite/questions/?user= not+user_name&filter=my-subscribes but how to make it !user_name and how to retrieve his own questions for which he has posted answer that will be a problem . again it seems multiple filters are not allowed . ??

but again it seems
EDIT
https://localhost/mysite/question/?filter=my-subscribes&sort=answers is allowed

This can be done by applying filter
dwqa_prepare_archive_posts

and modifying the query and another way can be overriding

add_action( 'dwqa_before_questions_list', array( $this, 'prepare_archive_posts' ) );

but the first one is better and I would recommend .

it will be

add_filter( 'dwqa_prepare_archive_posts', function( $query ){
   //  return modified query
   $query =  array( 'post_type' => 'dwqa-question', 'post__in' => array( 2, 5, 12, 14, 20 ) )
   return $query;
}

Hi Prafulla Kumar Sahu,

Thank you for getting in touch with us. Please try this code below here

add_filter( 'dwqa_prepare_archive_posts', 'dwqa_refilter_question' );
function dwqa_refilter_question( $args ) {
 if ( isset( $_GET['filter'] ) && $_GET['filter'] == 'my-answer' ) {
  $user_id = get_current_user_id();

  $answer_args = array(
   'post_type' => 'dwqa-answer',
   'posts_per_page' => 5,
   'no_found_rows' => true,
   'update_post_term_cache' => false,
   'update_post_meta_cache' => false,
   'orderby' => 'date',
   'order' => 'DESC',
   'fields' => 'ids',
   'meta_key' => '_question',
   'author' => get_current_user_id()
  );

  add_filter( 'posts_where', 'dwqa_answer_post_where' );
  add_filter( 'posts_clauses', 'dwqa_answer_posts_clauses' );
  add_filter( 'posts_distinct', 'dwqa_answer_post_distinct' );
  $questions = new WP_Query( $answer_args );
  remove_filter( 'posts_where', 'dwqa_answer_post_where' );
  remove_filter( 'posts_clauses', 'dwqa_answer_posts_clauses' );
  remove_filter( 'posts_distinct', 'dwqa_answer_post_distinct' );

  if ( $questions->have_posts() ) {
   $args['post__in'] = $questions->posts;
  }
 }

 return $args;
}

function dwqa_answer_post_join( $join ) {
 global $wpdb;
 if ( isset( $_GET['filter'] ) && $_GET['filter'] == 'my-answer' ) {
  $join .= 'JOIN {$wpdb->postmeta} ON {$wpdb->posts}.ID = {$wpdb->postmeta}.post_id ';
 }
}

function dwqa_answer_post_where( $where ) {
 global $wpdb;
 if ( isset( $_GET['filter'] ) && $_GET['filter'] == 'my-answer' ) {
  $user_id = get_current_user_id();
  $where .= " AND {$wpdb->postmeta}.meta_key = '_question' ";
 }

 return $where;
}

function dwqa_answer_posts_clauses( $clauses ) {
 global $wpdb;
 $clauses['fields'] = $wpdb->postmeta . '.meta_value';

 return $clauses;
}

function dwqa_answer_post_distinct( $distinct ) {
 return "DISTINCT";
}

thank you so much for your reply, already done it. something like

add_filter( 'dwqa_prepare_archive_posts', ' my_answered_by_user_function' );
  function my_answered_by_user_function( $query ){
    global $wp_query;
    if ( isset( $_GET['answers_of'] )  ){
      $answer_of = !empty( $_GET['answers_of'] ) ? $_GET['answers_of'] : 'all';
      unset( $args );
      $args = array( 'user' => $answer_of, 'posts_per_page' => -1 );
      $questions_answered = My_Class::my_dwqa_refilter_question( $args );
      $question_ids = array_unique( $questions_answered['post__in'] );
      $query = array( 'post_type' => 'dwqa-question', 'post__in' => $question_ids );
    }
    return $query;
  }

but thinking to use your .
