Question

我对编程很新，对Zend / Lucene索引也是如此。但据我所知，我的代码是正确的。我觉得我可能会忽略尝试上传更改并添加到数据库的步骤，以便它们出现在我的网站上的搜索中。我没有得到任何类型的错误消息。以下是控制器的代码。我想让我知道你是否需要其他任何东西来帮助这一点。提前感谢您提供的任何方向。

class SearchController extends Zend_Controller_Action
{

  public function init()
  {
    $auth = Zend_Auth::getInstance();

    if($auth->hasIdentity()) {
      $this->view->identity = $auth->getIdentity(); 
    }
 }

 public function indexAction()
 {
    // action body
 }

 public function buildAction()
 {
    // create the index
    $index = Zend_Search_Lucene::open(APPLICATION_PATH . '/indexes');
    $page = $this->_request->getParam('page');

    // build product pages
     if ($page == 'search') {
       $mdl = new Model_Search();
       $search = $mdl->fetchAll();
       if ($search->count() > 0) {
       foreach ($search as $s) {
         $doc = new Zend_Search_Lucene_Document();
         $doc->addField(Zend_Search_Lucene_Field::unIndexed('id', $s->id));
         $doc->addField(Zend_Search_Lucene_Field::text('name', $s->name));
         $doc->addField(Zend_Search_Lucene_Field::text('uri', $s->uri));
         $doc->addField(Zend_Search_Lucene_Field::text('description', $s->description));
         $index->addDocument($doc);
        }
       }
       $index->optimize();
       $this->view->indexSize = $index->numDocs();
  } 
 }

  public function resultsAction()
  {
    if($this->_request->isPost()) {
    $keywords = $this->_request->getParam('query');
    $query = Zend_Search_Lucene_Search_QueryParser::parse($keywords);
    $index = Zend_Search_Lucene::open(APPLICATION_PATH . '/indexes');
    $hits = $index->find($query);
    $this->view->results = $hits;
    $this->view->keywords = $keywords;
  } else {
    $this->view->results = null;
  }
}

}

Lucene索引不会自动与您的数据库保持同步，您需要重建整个索引，或者在更改时删除并重新添加相关文档（您无法编辑现有文档）。

public function updateAction()
{
   // something made the db change
   $hits = $index->find("name: " . $name);
   foreach($hits as $hit) {
     $index->delete($hit->id)  
   }

   $doc = new Zend_Search_Lucene_Document();
   // build your doc

   $index->add($doc);

}

请注意，lucene文档有自己的内部id属性，请注意不要将其误认为是您提供的id关键字。

在Zend Framework中使用Lucene进行索引添加/更改无效
