$options = array
(
　　'hostname' => 'localhost',
　　'port' => 8080,
　　'path' => 'solr/test'
);

$client = new SolrClient($options);

$query = new SolrQuery();

$query->setQuery('title:今日');

$query->setStart(0);

$query->setRows(50);

$query->addField('id')->addField('title');

$query_response = $client->query($query);

$response = $query_response->getResponse();

print_r($response);

结果如下

SolrObject Object ( [responseHeader] => SolrObject Object ( [status] => 0 [QTime] => 0 [params] => SolrObject Object ( [fl] => id,title [indent] => on [start] => 0 [q] => title:今日 [wt] => xml [rows] => 50 [version] => 2.2 ) ) [response] => SolrObject Object ( [numFound] => 2 [start] => 0 [docs] => Array ( [0] => SolrObject Object ( [id] => 324 [title] => 聚划算今日最大牌团购 ) [1] => SolrObject Object ( [id] => 333 [title] => 聚划算今日最大牌团购 ) ) ) )
