The news extensions is one of the most used extensions in the TYPO3 CMS. This configuration is made under the assumption with a page tree looking similar to this:

Example Pagetree of EXT:news setup

Example Pagetree of EXT:news setup

If you want to have a Crawler Configuration that matches this, you can add following to the PageTS for PageId 56.


tx_crawler.crawlerCfg.paramSets {
   tx_news = &tx_news_pi1[controller]=News&tx_news_pi1[action]=detail&tx_news_pi1[news]=[_TABLE:tx_news_domain_model_news; _PID:57; _WHERE: hidden = 0]
   tx_news {
     pidsOnly = 58

# _PID:57 is the Folder where news records are stored.
# pidSOnly = 58 is the detail-view PageId.

Now you can add the News detail-view pages to the crawler queue and have them in the cache and the indexed_search index if you are using that.

Respecting Categories in News

On some installations news is configured in such a way, that news of category A have their detail view on one page and news of category B have their detail view on another page. In this case it would still be possible to view news of category A on the detail page for category B (example.com/detail-page-for-category-B/news-of-category-A). That means that each news article would be crawled twice - once on the detail page for category A and once on the detail page for category B. It is possible to use a signal slot within news to prevent this.

On both detail pages include this typoscript setup:

plugin.tx_news.settings {
    # categories and categoryconjunction are not considered in detail view, so they must be overridden
    overrideFlexformSettingsIfEmpty = cropMaxCharacters,dateField,timeRestriction,archiveRestriction,orderBy,orderDirection,backPid,listPid,startingpoint,recursive,list.paginate.itemsPerPage,list.paginate.templatePath,categories,categoryConjunction
    # see the news extension for possible values of categoryConjunction
    categoryConjunction = AND
    categories = <ID of respective category>
    detail.errorHandling = pageNotFoundHandler

and register a signal slot in your site package.

        $signalSlotDispatcher = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance(




namespace Vendor\Ext\Slots;

class NewsDetailSlot
  public function detailActionSlot($newsItem, $currentPage, $demand, $settings, $extendedVariables): array
     if (!\is_null($newsItem)) {
           $demandedCategories = $demand->getCategories();
           $itemCategories = $newsItem->getCategories()->toArray();
           $itemCategoryIds = \array_map(function($category) {
              return (string)$category->getUid();
           }, $itemCategories);
            * Unset the news article if necessary, which - in conjunction with the above TypoScript - will cause a 404 error
           if (count($demandedCategories) > 0 && !$this->itemMatchesCategoryDemand($settings['categoryConjunction'], $itemCategoryIds, $demandedCategories)) {
              $newsItem = null;
     return [
           'newsItem' => $newsItem,
           'currentPage' => $currentPage,
           'demand' => $demand,
           'settings' => $settings,
           'extendedVariables' => $extendedVariables,

  protected function itemMatchesCategoryDemand(string $categoryConjunction, array $itemCategoryIds, array $demandedCategories): bool
     $numOfDemandedCategories = \count($demandedCategories);
     $intersection = \array_intersect($itemCategoryIds, $demandedCategories);
     $numOfCommonItems = \count($intersection);

     switch ($categoryConjunction) {
           case 'AND':
              return $numOfCommonItems === $numOfDemandedCategories;
           case 'OR':
              return $numOfCommonItems > 0;
           case 'NOTAND':
              return $numOfCommonItems < $numOfDemandedCategories;
           case 'NOTOR':
              return $numOfCommonItems === 0;

     return true;


Note that this does more than just prevent articles from being indexed twice. It actually prevents articles from being displayed on a page that is supposed to show only articles of a certain category!
