+#### Setting a default filter on the IndexAction
+By using ```$resourceCollection->getQuery()``` you can get access on the query object.
+use "r" alias for referring to the current entity. in this example the "r" refers to the "ProjectEntity"
+```php
+class ProjectController extends Controller
+{
+ /**
+ * @Route("/", name="projects_index", methods="GET")
+ */
+ public function index(ProjectRepository $projectRepository, ResourceCollection $resourceCollection): ResponseInterface
+ {
+ $resourceCollection->setRepository($projectRepository);
+
+ $resourceCollection->getQuery()->where('r.user_id = :s1')->setParameter(...);
+ $resourceCollection->handleIndexRequest();
+
+ return $this->jsonApi()->respond()->ok(
+ new ProjectsDocument(new ProjectResourceTransformer()),
+ $resourceCollection
