 * I need to adjust the query in the loop.php by adding tax_queries based on $REQUEST
   params. i tried something like this
 *     ```
       $argsExtended = array(
       	'tax_query' => array(
       		array(
       			'taxonomy' => 'my_custom_tag',
       			'slug' => 'slug',
       			'terms' => array( 'my_tag_slug' ),
       			'operator' => 'in',
       		),
       	)
       );
       $args = array_merge( $wp_query->query_vars, $argsExtended );
       query_posts( $args );
       ```
   
 * but this doesn’t seem to work. Any ideas?

 * loop.php is a theme-specific file, if it exists at all.
 * The proper way to modify is usually through pre_get_posts().
