[英]how to delete all the records from solr index
I am using solr to full text search. 我正在使用solr进行全文搜索。
I am new to solr and trying to delete the records from the solr index by php solarium client I am using the following code to delete the records: 我是solr的新手,并尝试通过php solarium客户端从solr索引中删除记录。我正在使用以下代码删除记录:
include_once("vendor/autoload.php");
$client = new Solarium\Client();
if(isset($_POST['delete']))
{
$update = $client->createUpdate();
// add the delete query and a commit command to the update query
$update->addDeleteQuery('*:*');
$update->addCommit();
// this executes the query and returns the result
$result = $client->update($update);
echo '<b>Update query executed</b><br/>';
echo 'Query status: ' . $result->getStatus(). '<br/>';
echo 'Query time: ' . $result->getQueryTime();
}
But it is giving me the following error on browser: 但这在浏览器中给了我以下错误:
