Question

我正在使用solr进行全文搜索。

我是solr的新手并试图通过php solarium客户端从solr索引中删除记录我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();
}

但它在浏览器上给我以下错误：

致命错误：未捕获的异常＆＃39; Solarium \ Exception \ HttpException＆＃39;消息＆＃39; Solr HTTP错误：OK（500）{＆＃34; responseHeader＆＃34;：{＆＃34; status＆＃34;：500，＆＃34; QTime＆＃34;：1}，＆＃ 34;错误＆＃34;：{＆＃34; trace＆＃34;：＆＃34; java.lang.NullPointerException \ n \ tat org.apache.lucene.search.BooleanClause.hashCode（BooleanClause.java:99）\ n \ tat java.util.AbstractList.hashCode（AbstractList.java:542）\ n \ tat org.apache.lucene.search.BooleanQuery.hashCode（BooleanQuery.java:520) \ n \ tat java.util.HashMap.put（ HashMap.java:389)\n\tat org.apache.lucene.index.BufferedUpdates.addQuery(BufferedUpdates.java:152）\ n \ tat org.apache.lucene.index.DocumentsWriterDeleteQueue $ QueryArrayNode.apply（DocumentsWriterDeleteQueue.java: 365）\ n \ tat org.apache.lucene.index.DocumentsWriterDeleteQueue $ DeleteSlice.apply（DocumentsWriterDeleteQueue.java:280）\ n \ tat org.apache.lucene.index.DocumentsWriterDeleteQueue.tryApplyGlobalSlice（DocumentsWriterDeleteQueue.java:200）\ n \ tat org.apache.lucene.index.DocumentsWriterDeleteQueue.addDelete（DocumentsWriterDeleteQueue.java:107）\ n \ tat org.apache.lucene.index.Docu第103行/var/www/library/Solarium/Core/Query/Result/Result.php中的mentsWriter.delete
