Use case

You can use the Ancestor Search Criterion to create a list of breadcrumbs leading to the Location:

``` php {skip-validation} hl_lines="2" $query = new LocationQuery(); query->query = new Criterion\Ancestor([this->locationService->loadLocation($locationId)->pathString]);

$results = this->searchService->findLocations(query); breadcrumbs = []; foreach (results->searchHits as $searchHit) { $breadcrumbs[] = $searchHit; }

return $this->render('parts/breadcrumbs.html.twig', [ 'breadcrumbs' => $breadcrumbs, ]);
