范例

Example #1 SolrClient::query() example

  <?php

$options  = array
(
     'hostname'  =>  'localhost' ,
     'login'     =>  'username' ,
     'password'  =>  'password' ,
     'port'      =>  '8983' ,
);

 $client  = new  SolrClient ( $options );

 $query  = new  SolrQuery ();

 $query -> setQuery ( 'lucene' );

 $query -> setStart ( 0 );

 $query -> setRows ( 50 );

 $query -> addField ( 'cat' )-> addField ( 'features' )-> addField ( 'id' )-> addField ( 'timestamp' );

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

 $response  =  $query_response -> getResponse ();

 print_r ( $response );

 ?>

以上例程的输出类似于：
