Solr
PHP Manual

PHP で Apache Solr エクステンションを使用する方法の例

例1 ブートストラップ・ファイルの内容

<?php

/* Solr サーバーのドメイン名 */
define('SOLR_SERVER_HOSTNAME''solr.example.com');

/* セキュアなモードで動作するかどうか */
define('SOLR_SECURE'true);

/* 接続する HTTP ポート */
define('SOLR_SERVER_PORT', ((SOLR_SECURE) ? 8443 8983));

/* HTTP Basic 認証ユーザー名 */
define('SOLR_SERVER_USERNAME''admin');

/* HTTP Basic 認証パスワード */
define('SOLR_SERVER_PASSWORD''changeit');

/* HTTP 接続タイムアウト */
/* HTTP データ転送動作に許される、秒単位の最大時間。既定値は30秒 */
define('SOLR_SERVER_TIMEOUT'10);

/* PEM 形式のプライベートキーとプライベート証明書に対するファイル名(その順序で連結されます) */
define('SOLR_SSL_CERT''certs/combo.pem');

/* PEM 形式のプライベート証明書のみに対するファイル名 */
define('SOLR_SSL_CERT_ONLY''certs/solr.crt');

/* PEM 形式のプライベートキーに対するファイル名 */
define('SOLR_SSL_KEY''certs/solr.key');

/* PEM 形式のプライベートキー・ファイルに対するパスワード */
define('SOLR_SSL_KEYPASSWORD''StrongAndSecurePassword');

/* 同等であることを証明する、一つ以上の CA 証明書を持つファイル名 */
define('SOLR_SSL_CAINFO''certs/cacert.crt');

/* 同等であることを証明する、複数の CA 証明書があるディレクトリ名 */
define('SOLR_SSL_CAPATH''certs/');

?>

例2 インデックスに文書を追加

<?php

include "bootstrap.php";

$options = array
(
    
'hostname' => SOLR_SERVER_HOSTNAME,
    
'login'    => SOLR_SERVER_USERNAME,
    
'password' => SOLR_SERVER_PASSWORD,
    
'port'     => SOLR_SERVER_PORT,
);

$client = new SolrClient($options);

$doc = new SolrInputDocument();

$doc->addField('id'334455);
$doc->addField('cat''Software');
$doc->addField('cat''Lucene');

$updateResponse $client->addDocument($doc);

print_r($updateResponse->getResponse());

?>

上の例の出力は、 たとえば以下のようになります。

SolrObject Object
(
    [responseHeader] => SolrObject Object
        (
            [status] => 0
            [QTime] => 446
        )

)

例3 ある文書を他の文書にマージ

<?php

include "bootstrap.php";

$doc = new SolrDocument();

$second_doc = new SolrDocument();

$doc->addField('id'1123);

$doc->features "PHP Client Side";
$doc->features "Fast development cycles";

$doc['cat'] = 'Software';
$doc['cat'] = 'Custom Search';
$doc->cat   'Information Technology';

$second_doc->addField('cat''Lucene Search');

$second_doc->merge($doctrue);

print_r($second_doc->toArray());


?>

例11 Facet Date の例

<?php

include "bootstrap.php";

$options = array
(
        
'hostname' => SOLR_SERVER_HOSTNAME,
        
'login'    => SOLR_SERVER_USERNAME,
        
'password' => SOLR_SERVER_PASSWORD,
        
'port'     => SOLR_SERVER_PORT,
);

$client = new SolrClient($options);

$query = new SolrQuery('*:*');

$query->setFacet(true);

$query->addFacetDateField('manufacturedate_dt');

$query->setFacetDateStart('2006-02-13T00:00:00Z');

$query->setFacetDateEnd('2012-02-13T00:00:00Z');

$query->setFacetDateGap('+1YEAR');

$query->setFacetDateHardEnd(1);

$query->addFacetDateOther('before');

$updateResponse $client->query($query);

$response_array $updateResponse->getResponse();

$facet_data $response_array->facet_counts->facet_dates;

print_r($facet_data);

?>

上の例の出力は、 たとえば以下のようになります。

SolrObject Object
(
    [manufacturedate_dt] => SolrObject Object
        (
            [2006-02-13T00:00:00Z] => 9

'ssl_cainfo' => SOLR_SSL_CAINFO,
);

$client = new SolrClient($options);

$query = new SolrQuery('*:*');

$query->setFacet(true);

$query->addFacetField('cat')->addFacetField('name')->setFacetMinCount(2)->setFacetMinCount(4'name');

$updateResponse $client->query($query);

$response_array $updateResponse->getResponse();

$facet_data $response_array->facet_counts->facet_fields;

print_r($facet_data);

?>

上の例の出力は、 たとえば以下のようになります。
