PHP添加、更新solr索引

 <?php
 $options = array
 (
     'hostname' => 'localhost',
     'port'     => '8080',
     'path'=>'solr/help_category',
     'wt'=>'json'
 );
 $client = new SolrClient($options); 

 $doc = new SolrInputDocument();

 $doc->addField('id', 501000);
 $doc->addField('title', 'Hello Wolrd');
 // $fields=$doc->getField ('id');
 // var_dump($fields);exit;
 $response = $client->addDocument($doc);
 var_dump($response);
 $client->commit();
 ?>

当索引文档中主键id值存在时，会更新原文档，不存在则会添加文档
