我该怎么办？

在我的项目中,Solr bundle使用这个：

use SolrClient;
use SolrQuery;
use SolrObject;
use SolrDocument;
use SolrInputDocument;

在基本的twig文件中：

<form action="{{ path("home_search") }}" method="get">
  <input type="search" name="search"><br>
  <input type="submit" value="search">
</form>

我的控制器的一些例子：

public function searchAction($templateName = '')
{
 $solrService = $this->get('rocket.solr_service');

    $solrQuery = new SolrQuery('*:*');
    $solrQuery->addField('id')
        ->addField('name');


    if (!empty($templateName)) {
        $solrQuery->addFilterQuery(sprintf('name:"%s" OR design_template_tag_name:"%1$s" OR design_category_name:"%1$s"',$templateName));
    }


    $solrQuery->setRows(1000);

    $solrObject = $solrService->query(
        'RocketBraPrintBundle:DesignTemplate',$solrQuery,SolrService::WRITER_FORMAT_SOLR_OBJECT
    );

    $templates = $solrObject->offsetGet('response')->offsetGet('docs');
    if (!$templates) {

        if (!empty($templateName)) {
            $this->setFlash('catalog-message','No results found for your search.');
            return $this->searchDesignTemplates($categoryTreeSlug,$productFamilyFaceId);
        }

        return array();
    }

    return $templates;

}

但是在这个渲染的twig文件中,我不知道我会写什么.
