我正在使用 Symfony 2.1 构建的工作门户网站。我已经实现ewz/EWZSearchBundle了求职过程，如下所示：

/**
 * Displays a form to create a new Job entity.
 *
 * @Route("/new", name="job_new")
 * @Template("JobBundle:Job:new.html.twig")
 */
public function newAction(Request $request)
{
    $entity = new Job();
    $form   = $this->createForm(new JobType(), $entity);

    if('POST'===$request->getMethod()){
        $form->bind($request);

        if ($form->isValid()) {

            $entity->setOwner($this->getEmployer());

            $em = $this->getDoctrine()->getManager();
            $em->persist($entity);
            $em->flush();

            $location = $entity->getLocation();
            $loName = array();
            foreach ($location as $key => $loc) {
                $loName[] = $loc->getName();
            }

            $industry = $entity->getIndustry();
            $inName = array();
            foreach ($industry as $key => $ind) {
                $inName[] = $ind->getTitle();
                }
            $skills = $entity->getSkills();
            $skillName = array();
            foreach ($skills as $key => $skl) {
                $skillName[] = $skl->getTitle();
                }

            $education = $entity->getEducation();
            $educationName = array();
            foreach ($education as $key => $edu) {
                $educationName[] = $edu->getTitle();
                }

            $search = $this->get('ewz_search.lucene');

            $document = new Document();
            $document->addField(Field::keyword('key', $entity->getId()));
            $document->addField(Field::text('title', $entity->getTitle()));
            $document->addField(Field::text('url', $this->generateUrl('job_show', array('slug' => $entity->getSlug()))));
            $document->addField(Field::unstored('body', $entity->getDescription()));
            $document->addField(Field::text('location', implode(" ", $loName)));
            $document->addField(Field::text('industry', implode(" ", $inName)));
            $document->addField(Field::text('skills', implode(" ", $skillName)));
            $document->addField(Field::text('education', implode(" ", $educationName)));


            $search->addDocument($document);
            $search->updateIndex();

            return $this->redirect($this->generateUrl('job_show', array('slug' => $entity->getSlug())));
        }

    }

    return array(
        'entity' => $entity,
        'form'   => $form->createView(),
    );
}

当候选人通过以下任何领域搜索工作时，它工作得非常好：位置、行业、技能或教育。但是我有两个问题：

  1. 在这个过程中，对于每个领域（位置、技能、行业或教育），只有一个职位搜索适用，而我想要单独的搜索表单，例如在位置搜索中，只有位置字段匹配，而不匹配其他剩余字段。

  2. 第二个问题是当雇主删除他的工作时，被删除工作的索引也会显示在搜索过程中，而在工作被删除后，被删除工作的索引也应该从搜索索引中删除。

我试图job_delete通过以下代码删除操作时间的搜索索引：

/**
 * Deletes a Job entity
 * @Route("/{slug}/delete", name="job_delete")
 * @Method("POST")
 */
public function deleteAction(Request $request, $slug)
{
    $em = $this->getDoctrine()->getManager();
            $entity = $em->getRepository('JobBundle:Job')
           ->findOneBy(array('slug' => $slug));

     if (!$entity) {
            throw $this->createNotFoundException('Unable to find Job entity.');
        }       

    $form = $this->createDeleteForm($entity->getSlug());
    $form->bind($request);       
    if ($form->isValid()) {

    $this->checkOwnerSecurity($entity); 

        $em->remove($entity);
        $em->flush();
        $search = $this->get('ewz_search.lucene');
        $index = $search->getIndex();
        $removePath = 'http://localhost/Jobtook/web/app_dev.php/employer/job/{slug}/delete';
        $hits = $index->find('job_delete' . $removePath);
        foreach ($hits as $hit) {
        $index->delete($hit->id);
        }
    }   

    return $this->redirect($this->generateUrl('job'));
}

private function createDeleteForm($slug)
{
    return $this->createFormBuilder(array('slug' => $slug))
        ->add('slug', 'hidden')
        ->getForm()
    ;
}

但是通过这段代码，当我创建许多作业并只删除一个作业时，所有作业都会从搜索索引中删除，即使剩余的作业仍然存在于数据库中。我不知道我做错了什么。
