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();
}

但它在浏览器上给了我以下错误:

致命错误:未捕获的异常 'Solarium\Exception\HttpException' 带有消息 'Solr HTTP 错误:OK (500) {"responseHeader":{"status":500,"QTime":1},"error":{"trace" :"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.DocumentsWriter.delete in /var/www/library/Solarium/Core/Query/Result/Result.php 在第 103 行

使用以下查询从 solr 中删除您的记录 -

  1. 域:[端口]/solr/#/collection1/query
  2. 将请求处理程序(qt)“/select”更改为“/delete”
  3. 删除所有记录 q = :并按回车
  4. 对于删除特定 id id: 并按 enter

如果您想删除所有索引,那么您也可以使用浏览器。只需将以下链接复制并粘贴到浏览器中即可。 http://localhost:8983/solr/update?stream.body=:&commit=true
