Rebuild taxonomy_index table for all nodes

test.php

<?php

$query = \Drupal::entityQuery('node');
$ids = $query->accessCheck(FALSE)->execute();
$storage_handler = \Drupal::entityTypeManager()->getStorage('node');
// If you have a lot of nodes, you may have to split this up via
// array_chunk() instead of trying to load all nodes at one time.
$entities = $storage_handler->loadMultiple($ids);
foreach ($entities as $entity) { 
  taxonomy_build_node_index($entity);
