我正在尝试在控制台命令中使用 zend lucene 索引包含超过 3000 条记录的表

这是我的代码 

public function run($args) {
    set_time_limit(0);      
    Yii::import('application.vendors.*');
    require_once 'Zend/Search/Lucene.php';

    Zend_Search_Lucene_Search_QueryParser::setDefaultEncoding('utf-8');
    Zend_Search_Lucene_Analysis_Analyzer::setDefault(
            new Zend_Search_Lucene_Analysis_Analyzer_Common_Utf8_CaseInsensitive ()
    );

    $searchPath = Yii::app()->runtimePath.'/search';
    $index = Zend_Search_Lucene::create($searchPath);
    /*
     * fecth data to index
     */ 
    $sql = 'select id, title, content, succinct, create_time from `news` where status="published"';
    $query = Yii::app()->db->createCommand($sql);
    $result = $query->queryAll();

    foreach ($result as $data) {
        $doc = new Zend_Search_Lucene_Document();
        $doc->addField(Zend_Search_Lucene_Field::Text('title',
            CHtml::encode($data['title']), 'UTF-8')
        );
        $doc->addField(Zend_Search_Lucene_Field::Text('succinct',
                strip_tags($data['succinct']), 'UTF-8')
        );          
        $doc->addField(Zend_Search_Lucene_Field::UnStored('content',
                strip_tags($data['content']), 'UTF-8')
        );
        $doc->addField(Zend_Search_Lucene_Field::UnIndexed('newsId',
                $data['id'], 'UTF-8')
        );
        $doc->addField(Zend_Search_Lucene_Field::UnIndexed('create_time',
                $data['create_time'], 'UTF-8')
        );
        $index->addDocument($doc);          
    }
    $index->commit();
    $index->optimize(); 
}

}

但我得到这个错误

内存不足（需要 228480 字节）
异常“CDbException”和消息“CDbCommand 无法执行 SQL 语句：SQLSTATE[HY000]：一般错误：2008 MySQL 客户端内存不足。执行的SQL语句为：select id, title, content, succinct, create_time from newswhere status="published"' in /home/user/public_html/v2/lib/framework/db/CDbCommand.php:528

有什么建议吗？

不久前我遇到了类似的错误。我可以通过增加数据库缓存来修复它。您还可以尝试增加 php 解释器在执行期间获得的内存量（客户端内存不足）。它也可以帮助你。
