Symfony和Zend高级搜索Lucene



我使用Symfony 1.4.11。我将搜索添加到我的项目中,就像在Jobeet教程中一样。但我还需要进行高级搜索。例如,用户可以іудусе"县"one_answers"类别"。我制作表单并阅读本教程。我还发现了这个。但是我现在不打算把查询分成几个部分。

我班上

public function updateLuceneIndex()
{
  $index = $this->getTable()->getLuceneIndex();
    // remove an existing entry
    if ($hit = $index->find('pk:'.$this->getAdId()))
    {
      $index->delete($hit->Adid);
    }
    // don't index expired and non-activated 
    if (!$this->getActive())
    {
      return;
    }
    $doc = new Zend_Search_Lucene_Document();
    // store  primary key URL to identify it in the search results
    $doc->addField(Zend_Search_Lucene_Field::UnIndexed('pk', $this->getAdId()));

  $doc->addField(Zend_Search_Lucene_Field::UnStored('address', $this->getAddress(), 'utf-8'));
  $doc->addField(Zend_Search_Lucene_Field::UnStored('company', $this->getCompany(), 'utf-8'));
  $doc->addField(Zend_Search_Lucene_Field::UnStored('country', $this->getCountry(), 'utf-8'));
  $doc->addField(Zend_Search_Lucene_Field::UnStored('contact_person', $this->getContactPerson(), 'utf-8'));
  $doc->addField(Zend_Search_Lucene_Field::UnStored('phone', $this->getPhone(), 'utf-8'));
  $doc->addField(Zend_Search_Lucene_Field::UnStored('email', $this->getEmail(), 'utf-8'));
  $doc->addField(Zend_Search_Lucene_Field::UnStored('title', $this->getTitle(), 'utf-8'));
  $doc->addField(Zend_Search_Lucene_Field::UnStored('content', $this->getContent(), 'utf-8'));
  $doc->addField(Zend_Search_Lucene_Field::UnStored('category_id', $this->getCategoryId(), 'utf-8'));

  $index->addDocument($doc);
  $index->commit();
  }
表类

public function getAdsLuceneQuery($query)
{
 ProjectConfiguration::registerZend();
 $query = Zend_Search_Lucene_Search_QueryParser::parse($query);
    $hits = self::getLuceneIndex()->find($query);
  $pks = array();
  foreach ($hits as $hit)
  {
    $pks[] = $hit->pk;
  }
  if (empty($pks))
  {
    return array();
  }
  $q = $this->createQuery('a')
    ->whereIn('a.AdId', $pks)
    ->limit(20);
  $q = $this->createQuery('a')
           ->andWhere('a.active = ?',1)
             ->leftJoin('a.Owner o')
           ->leftJoin('o.Profile p')
           ->andWhere('p.payed_until > NOW()')
           ->andWhere('a.expires_at > NOW()')
     ->addORDERBY ('created_at DESC');
  return $q->execute();
}
 public function getLuceneIndex()
  {
    ProjectConfiguration::registerZend();
    if (file_exists($index = $this->getLuceneIndexFile()))
    {
      return Zend_Search_Lucene::open($index);
    }
    else
    {
      return Zend_Search_Lucene::create($index);
    }
  }
static public function getLuceneIndexFile()
{
  return sfConfig::get('sf_data_dir').'/ads.'.sfConfig::get('sf_environment').'.index';
}

在lucene查询中,您可以告诉要在哪个字段中查找值,请参阅文档的相关部分。

它的工作原理如下:

title:"The Right Way" AND text:go
